Presents the introductory welcome message from the conference proceedings. May include the conference officers' congratulations to all involved with the conference event and publication of the proceedings record.
To pchieve desired levels of operational performance, air and ground target surveillance systems require enhanced capabilities for identifying targets within the surveillance space. The objective of this study is to present a novel experimental laboratory design of a passive-illumination target recognition system. Polarimetric Exploratory Data Analysis (pEDA) has been applied for the detection and...
After the big impact of optical 3D-imaging processing, multi- and hyperspectral imaging solutions will be the next technological innovation in image processing for industrial application. This work presents a clever and affordable solution for multispectral imaging: a smart imager for measurements spanning 400 nm to 950 nm in a 50 nm step with 50 nm bandwidth. With a combination of industrial interface...
Fractal Image Compression (FIC) is one of the most popular techniques used in image and video compression due to its simplicity and superior performance. The main drawback of FIC arises from its time consuming operation, especially when a full search is attempted. Hence, it is very challenging to achieve a real-time operation if this algorithm is implemented in general processor unit. In this paper,...
Electrical Impedance Tomography (EIT) is a kind of functional imaging technology which has great potential for tumor diagnosis, and physiological process monitoring. This article introduces a prototype design of a semi-parallel EIT data acquisition system with the purpose of ease of hardware upgrades and scalability. The system consists of one control module and an expandable number of independent...
Texture analysis has been an important research area due to wide range of applications in the field of image processing, machine vision and pattern recognition. In this paper, we present a comprehensive analysis of texture descriptors for texture classification. We focus on state of the art texture descriptors which have been widely used for classification in literature and shown promising results...
Advanced robotics systems in human frequented environments need to be equipped with avant-garde capabilities, so as to attain a social behavior acceptable by their human proprietors. Therefore, robots should learn and react properly when they share a common domain with humans and adjust their operation according to the activity of the people around. This paper proposes a social mapping method which...
Motion parameters estimation is a crucial key to blur star restoration which is helpful to improve dynamic performance of star sensor. However, motion blur under high dynamic conditions results in signal-to-noise ratio (SNR) decreasing seriously which brings about difficulties in motion parameters estimation. In our paper, an improved Radon transform by introducing a combination of Z-function and...
Refining the information about the tissue is achieved by the standardization of color in whole-slide images and digital images of tissue sections. The investigation described in this paper proposes a solution to the problems of color dissimilarity for microscope slides digitalized by various equipment. A method of color standardization using color calibration microscope slide is proposed and a piece...
The aim of this study was to develop a novel algorithmic scheme for self-organizing data, adopting an recursive-mode k-means clustering approach. The proposed methodology attempts to refine and improve the clustering result by sequentially updating centers on the basis of their present and previous positions, exploiting both prior expert knowledge and posterior data information from the statistical...
RANSAC is a popular and robust fitting algorithm. In the field of image processing, RANSAC can be successfully used to reject false correspondences between similar images. Due to its iterative nature, RANSAC is computationally demanding and time consuming. When the target application operates in real-time, conventional approaches based on personal computers usually fail to meet the requirements. In...
Important considerations to major components like cameras, optics, and illuminators of an in-line photoluminescence imaging system to detect micro-cracks in crystalline silicon solar cells are presented. A compromise between image resolution and speed is needed when designing a practical machine vision inspector. Generally, CCD cameras are preferred since they are relatively cheaper compared to InGaAs...
An instrument for measuring water droplets is described and constructed. It is designed to measure the volume concentration and the size distribution of droplets in order to detect icing conditions in a natural fog. The instrument works by shadowgraph imaging, with a collimated blue LED as background illumination. We show how to use a reference object to obtain a calibration of the droplet size and...
A mechanical counter-steering prototype which includes a mechanical slider system was developed to evaluate tracking and prediction algorithms used for tumor motion compensation. The compensation aims to maintain a stationary tumor with respect to the radiation beam. Motion tracking was performed with an optical flow algorithm. Three techniques of reference image registration were evaluated. To compensate...
Wireless capsule endoscopy (WCE) is the prime diagnostic modality for the small-bowel. It consists in a swallowable color camera that enables the visual detection and assessment of abnormalities, without patient discomfort. The localization of the capsule is currently performed in the 3D abdominal space using radiofrequency (RF) triangulation. However, this approach does not provide sufficient information...
More and more modern technologies are used for designing clothes. One of these technologies is simulation of garments. For simulation some mechanical parameters like Youngsmodulus, Shear-modulus, bending stiffness, surface weight, coefficient of friction between fabric and skin and between like materials, and thickness are necessary and need to be determined through precise measurement. Especially...
This paper presents an initial investigation into using estimated reflectance, derived from raw terrestrial laser scanner intensity data, to model clay content within a potash mine. The mines of interest are located in the Prairie Evaporite Formation about 1 kilometre underground in the province of Saskatchewan, Canada. It is shown that with an appropriate reflectance estimation process it is possible...
