Previous visual object tracking methods employ image-feature regression models or coordinate autoregression models for bounding box prediction. image-feature regression methods heavily depend on matching results and do not utilize positional prior, while the autoregressive approach can only be trained using bounding boxes available in the training set, potentially resulting in suboptimal performance during testing with unseen data. Inspired by the diffusion model, denoising learning enhances the model's robustness to unseen data. Therefore, We introduce noise to bounding boxes, generating noisy boxes for training, thus enhancing model robustness on testing data. We propose a new paradigm to formulate the visual object tracking problem as a denoising learning process. However, tracking algorithms are usually asked to run in real-time, directly applying the diffusion model to object tracking would severely impair tracking speed. Therefore, we decompose the denoising learning process into every denoising block within a model, not by running the model multiple times, and thus we summarize the proposed paradigm as an in-model latent denoising learning process. Specifically, we propose a denoising Vision Transformer (ViT), which is composed of multiple denoising blocks. In the denoising block, template and search embeddings are projected into every denoising block as conditions. A denoising block is responsible for removing the noise in a predicted bounding box, and multiple stacked denoising blocks cooperate to accomplish the whole denoising process. Subsequently, we utilize image features and trajectory information to refine the denoised bounding box. Besides, we also utilize trajectory memory and visual memory to improve tracking stability. Experimental results validate the effectiveness of our approach, achieving competitive performance on several challenging datasets. The proposed in-model latent denoising tracker achieve real-time speed, rendering denoising learning

This paper is dedicated to the research and development of automated methods for detecting bacterial colonies on photographic images of Petri dishes. We propose a segmentation algorithm for microbiological photographic images which is based on the convolutional neural network architecture of the encoder-decoder class, trained on artificially generated image data. Our method consists of two stages: sliding window imageprocessing by the proposed neural network to find areas containing isolated objects potentially suitable for further research, and further segmentation of the resulting binary area map into regions containing colonies by classical computer vision algorithms. According to the experimental research, the developed algorithm shows the best results in comparison with the existing neural network algorithms we adapt in this work as well as watershed segmentation algorithms. The work also proposes algorithms for microbiological photographic images artifact searching based on heuristic and neural network approaches (including flare, magnetic balls, barcodes and condensate), the use of which allows to increase the quality of the image segmentation algorithm, as well as to find errors caused by the human factor. The results of this work might be further used for classification algorithms of the bacterial colonies in the segments found, which will allow in some cases fully automated process of visual bacteria recognition on Petri dishes photographic images.

Visual impairments are a global health issue with profound socioeconomic ramifications in both the developing and the developed world. There exist ongoing research projects, that aim to investigate the influence of light in the perception of low vision individuals. But as of today, there is neither clear knowledge nor extensive data regarding the influence of light in low vision situations. This research will address these issues by introducing a methodology and a system to simulate visual impairments. A pipeline based on eye anatomy coupled with real-time imageprocessingalgorithms allows to dynamically simulate low vision specific characteristics of selected impairments in mixed reality. An original new approach based on massively parallelized processing combined with an efficient modeling of eye refractive errors aims to improve the accuracy of the low vision simulation.

Humans express emotions verbally and non-verbally through their voice, facial expressions, and body language. Facial expression recognition systems can identify the emotional state of any person by using different intelligent algorithms, such as Support Vector Machines, Hidden Markov Models, and Convolutional Neural Networks, among others. This study focuses on facial expression recognition using eye and mouth regions of images from the FER-2013 dataset by training convolutional neural network (CNN) models. Seven emotional states - happy, sad, fear, anger, disgust, surprise and neutral - were identified. The methodology included segmenting and concatenating the images to form three CNN models. The best-performing model, a four-layer CNN with 8, 16, 32, and 64 filters, achieved remarkable results: 99.05% accuracy, 100.00% precision, 93.75% recall, 96.77% F1-score, 95.95% validation accuracy, and a 0.15 validation loss with a processing time of 3.03 minutes. It was possible to develop a CNN model capable of identifying seven emotional states from only the data of the eye and mouth region using concatenated images.
