The development of Internet of Things technology provides a real-time data collection platform for laboratory management, and data visualization provides new ideas for object-oriented behavior management. This article introduces an intelligent laboratory management system with a computer as the core and introduces it in detail. This article compares the performance of typical visualization systems at home and abroad, and discusses the development and implementation of a typical intelligent laboratory management system, the visual expression of the system, and its impact on the behavior of experimenters. The article empirically analyzes the role of behavior in laboratory learning and proposes ideas for further development (Before the system was put into use, employees in the position spent 2.18 h processing laboratory data every day, and after the system was put into use, it only took 1.02 h, indicating that the put into use of the system can effectively reduce the time spent on data processing). © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

visual processing and classification of items on a moving conveyor:: a selective perception approach

Many industrial applications require some sort of automated visual processing and classification of items placed on a moving conveyor. In this paper, we present a selective perception based approach to visual processing, The novelty of this approach is that instead of processing the whole image, only areas that are deemed "interesting" and hence calling for attention are analyzed. The attentional sequences thus constructed can then be used for a variety of tasks including shape determination. Since only a small portion of the whole image is processed, visual processing can be real-time and flexible without requiring special hardware. Two different applications based on this approach are described. In a defective item detection task, we explain in detail how attentional sequences can be used. As a second application, the approach has been implemented in an automated remote controller sorter in a TV manufacturing plant-thus confirming its practical applicability.

Deficits in visual processing are early cognitive abnormalities in patients with Huntington's disease (HD) and may be found in presymptomatic gene carriers. We investigated the nature and evolution of deficits in visual processing in HD, and whether subtle deficits could be recognized by formal testing in asymptomatic carriers. We studied 35 patients with HD in stages 1-3 of functional disability, and 26 symptom-free relatives at 50% risk for the disease. We administered the Mini Mental State Examination to assess overall cognitive function and tests to assess visuospatial skills such as visual attention and ocular scanning (Cancellation Task and Line Bisection Test), visuoconstructive abilities (Copy of Rey's Complex Figure), and visuoperception (Hooper visual Organization Test). The group at risk comprised 15 asymptomatic carriers (AC) and 11 non-carriers (NC) and was assessed by investigators blinded to gene status. HD patients were impaired in most of the tasks compared with AC and NC, and the scores declined steadily from stage 1 to 3. However, the difference between patients in stage 1 of HD and AC and NC in most of the tasks was not significant. Only the Hooper Test, which requires complex visual integration, was highly discriminative of early symptomatic from asymptomatic carriers (P < 0.05). There were no significant differences between AC and NC in any of the tasks. We conclude deficits in visual processing develop with other manifestations of the disease and are not significant on formal testing at presymptomatic stages;also, early visual deficits in HD seem to be related to disorders in complex visual processing.

Patients with Alzheimer's disease (AD) typically present with attentional and oculomotor abnormalities that can have an impact on visual processing and associated cognitive functions. Over the last few years, we have witnessed a shift toward the analyses of eye movement behaviors as a means to further our understanding of the pathophysiology of common disorders such as AD. However, little work has been done to unveil the link between eye moment abnormalities and poor performance on cognitive tasks known to be markers for AD patients, such as the short-term memory-binding task. We analyzed eye movement fixation behaviors of thirteen healthy older adults (Controls) and thirteen patients with probable mild AD while they performed the visual short-term memory binding task. The short-term memory binding task asks participants to detect changes across two consecutive arrays of two bicolored object whose features (i.e., colors) have to be remembered separately (i.e., Unbound Colors), or combined within integrated objects (i.e., Bound Colors). Patients with mild AD showed the well-known pattern of selective memory binding impairments. This was accompanied by significant impairments in their eye movements only when they processed Bound Colors. Patients with mild AD remarkably decreased their mean gaze duration during the encoding of color-color bindings. These findings open new windows of research into the pathophysiological mechanisms of memory deficits in AD patients and the link between its phenotypic expressions (i.e., oculomotor and cognitive disorders). We discuss these findings considering current trends regarding clinical assessment, neural correlates, and potential avenues for robust biomarkers.

Objective: To investigate visual processing over the inferior temporal cortex (ITC) by recording intracranial event-related potentials (IERPs), and correlating the results with those of electrocortical stimulation mapping (ESM). Methods: IERPs to word, non-word, and non-letter visual stimuli were recorded over the ITC in 6 patients with intractable epilepsy. Two patients underwent ESM of the same contacts. Results: IERPs were observed at 18 electrodes in 4 out of 6 patients. Nine electrodes showed early IERPs (peak latency 6 200 ms) over the posterior and middle ITC and 7 of them showed a following late ERP component, "early + late IERPs". Nine electrodes showed late IERPs (peak latency <= 200 ms) over the middle and anterior ITC. Among four electrodes showing language or visual phenomena by ESM, one electrode showed a short latency IERP, another electrode showed a late IERP, and the remaining two electrodes showed no IERPs. Conclusions: Our findings further support that the visual recognition occurred sequentially from posterior to anterior ITC. Dissociation of IERPs and ESM may be explained by the methodological difference. Significance: IERP study disclosed that visual recognition occurred sequentially from posterior to anterior ITC.

Global spatial and motion processing abilities were assessed in 18 patients with Noonan syndrome (NS) and in 43 matched controls using form and motion coherence testing, respectively. We observed a discrepancy between the two groups since the study group had significantly lower performances than the control group for form coherence while there was no impairment on motion coherence. All the patients were also assessed on the Movement Assessment Battery for Children (M-ABC) to evaluate visuomotor skills. Thirteen of the 18 (72%) also had global poor performances on the M-ABC. The results show that children with NS have a specific impairment in the global processing of visuospatial information and are likely to have a specific ventral stream deficit as also suggested by the frequent visuomotor perceptual difficulties. Testing form and motion coherence thresholds may be a useful diagnostic tool for this group of patients, despite their normal cognitive abilities, since aspects of global form processing and visuomotor perceptual difficulties can be identified and potentially targeted for a specific rehabilitation program.

visual processing characteristics of children with Meares-Irlen syndrome

The potential role of visual processing deficits in reading difficulty was brought to public attention by claims that a large proportion of children with dyslexia suffer from a perceptual dysfunction currently referred to as Meares-Irlen syndrome (MISViS). A previous study showing that visual perceptual measures involving visual memory and discrimination predict independent variance in reading achievement [J. Learn. Disabil. 28 (1995) 216] provides a basis to examine their relationships with the diagnostic criteria of MISViS. This study examined these visual processing characteristics in 36 eight- to ten-year-old children, half of whom were experiencing reading difficulty. Children were assessed for MISViS by Irlen screeners;approximately half of the participants in each group were positively identified. Concurrent performance on standardized visual processing tests showed that while a positive diagnosis of MISViS is not indicative of reading ability, nor in particular of a visual-processing deficit subtype identified by Watson and Willows [J. Learn. Disabil. 28 (1995) 216], MISViS can indicate visual processing difficulties potentially related to visual attention inefficiency.

visual processing, learning and feedback in the primate eye movement system

TRENDS IN NEUROSCIENCES 2009年第11期32卷 583-590页

We present an overview of recent paradigms used for studying visual information and reward processing in the human and monkey oculomotor pathways. Current evidence indicates that eye movements made during visual search tasks rely on neural computations similar to those employed when eye movements are planned and executed to obtain explicit rewards. These data suggest that human eye movements originate from the processing of (predominantly visual) sensory information, feedback about previous errors, and expectations about factors, such as reward. We conclude that these properties make the saccadic system an ideal model for studying both the behavioral and neural mechanisms for human voluntary and involuntary choice behavior.

visual processing of Contour Patterns under Conditions of Inattentional Blindness

引用

JOURNAL OF COGNITIVE NEUROSCIENCE 2012年第2期24卷 287-303页

作者： Pitts, Michael A. Martinez, Antigona Hillyard, Steven A. Univ Calif San Diego Sch Med Dept Neurosci La Jolla CA 92093 USA Nathan S Kline Inst Psychiat Res Orangeburg NY USA

An inattentional blindness paradigm was adapted to measure ERPs elicited by visual contour patterns that were or were not consciously perceived. In the first phase of the experiment, subjects performed an attentionally demanding task while taskirrelevant line segments formed square-shaped patterns or random configurations. After the square patterns had been presented 240 times, subjects' awareness of these patterns was assessed. More than half of all subjects, when queried, failed to notice the square patterns and were thus considered inattentionally blind during this first phase. In the second phase of the experiment, the task and stimuli were the same, but following this phase, all of the subjects reported having seen the patterns. ERPs recorded over the occipital pole differed in amplitude from 220 to 260 msec for the pattern stimuli compared with the random arrays regardless of whether subjects were aware of the patterns. At subsequent latencies (300-340 msec) however, ERPs over bilateral occipital-parietal areas differed between patterns and random arrays only when subjects were aware of the patterns. Finally, in a third phase of the experiment, subjects viewed the same stimuli, but the task was altered so that the patterns became task relevant. Here, the same two difference components were evident but were followed by a series of additional components that were absent in the first two phases of the experiment. We hypothesize that the ERP difference at 220-260 msec reflects neural activity associated with automatic contour integration whereas the difference at 300-340 msec reflects visual awareness, both of which are dissociable from task-related postperceptual processing.

visual processing DELAYS ALTER THE PERCEIVED SPATIAL FORM OF MOVING GRATINGS

引用

VISION RESEARCH 1993年第18期33卷 2733-2746页

作者： ANDERSON, SJ [*]Department of Vision Sciences Aston University Birmingham B4 7ET England

This study shows that there are delays in processing high spatial frequencies relative to low frequencies, and that these may affect the perceived brightness profile of drifting waveforms. The stimuli were complex waveforms consisting of 2-3 sinusoidal components, either drifting or stationary. The phase of the components was varied until the brightness profile of the waveform appeared as a square, triangle, ramp or bar. The results indicate that stationary waveforms are perceived veridically, but drifting waveforms are not. The harmonics of a drifting complex wave must be phase advanced, relative to the fundamental, in order to cancel motion-induced waveform distortions. This suggests that during visual processing the harmonics must be phase delayed, indicating that they are being processed more slowly than the fundamental. The most significant delays appear to be those between the fundamental and its second and third harmonic. Furthermore, the results show that the magnitude of the delays is dependent on the phase relationship between the components at perceptually significant points in the waveform: delays are less when the components are in sine phase than when they are in cosine phase. Separate experiments show that the detectability of phase shifts is least when the components are in sine phase. Together, these results may explain why drifting ''sharp-edged'' stimuli are not perceptually distorted: the human visual system appears to be relatively insensitive to phase shifts around square-wave phase and may therefore tolerate differences in the processing times of certain harmonics. A discussion of the possible origin of these processing delays is presented, together with the hypothesis that frequency dependent delays may reflect the spatiotemporal inseparability of cortical visual units.
