In this paper we present the results of applying data compression to a three-dimensional object recognition technique based on phase-shift digital holography. Industry-standard lossless data compression algorithms were first applied. Next, lossy techniques based on subsampling, discrete cosine transformation, and discrete Fourier transformation were examined. We used normalized cross-correlation in the object plane as our performance metric. For each hologram tested, we found that as many as 90% of the cosine and Fourier components could be removed, without significant loss in correlation performance.
We show that differentiation via fitting B-splines to the spatio-temporal intensity data comprising an image sequence provides at least the same and usually better 2D Lucas and Kanade optical flow than that computed v...

The blood pressure (systolic and diastolic) and heart rate of a patient were tested hourly during about 24-hours. Such a test is well-known in many clinics as ambulatory blood pressure monitoring. It is a standard for hypertension diagnostics. Usually, these three data sets are considering separately as different time series. Each series delivers its own information. We propose another approach, considering each measuring as a three-dimensional vector of the patient state at the given moment. Indeed, this vector is an image, that is a moment describing of patient's state. Thereby, the entire test might show us the dynamic of the state in the phase space during the observation period. The idea is borrowed from the patternrecognition and perhaps will sound well for the processing.and visualization of monitoring results. According to the presented findings, the model of information system based on Micro-Electro-Mechanical System (MEMS) sensor for data collection and processing. The mathematical apparatus for the system has been adopted to the requirements for devices with low computational power. Thus, it can be implemented using modern micro controllers.

In recent years, the task of estimating the 6D pose of object instances and complete scenes, i.e. camera localization, from a single input image has received considerable attention. Consumer RGB-D cameras have made this feasible, even for difficult, texture-less objects and scenes. In this work, we show that a single RGB image is sufficient to achieve visually convincing results. Our key concept is to model and exploit the uncertainty of the system at all stages of the processing.pipeline. The uncertainty comes in the form of continuous distributions over 3D object coordinates and discrete distributions over object labels. We give three technical contributions. Firstly, we develop a regularized, auto-context regression framework which iteratively reduces uncertainty in object coordinate and object label predictions. Secondly, we introduce an efficient way to marginalize object coordinate distributions over depth. This is necessary to deal with missing depth information. Thirdly, we utilize the distributions over object labels to detect multiple objects simultaneously with a fixed budget of RANSAC hypotheses. We tested our system for object pose estimation and camera localization on commonly used data sets. We see a major improvement over competing systems.
