The aim of the research is to present an approach of obstacle distance estimation and navigation for smart wheelchair. The smart wheelchair is an electric wheelchair equipped with camera and line laser to navigate and avoid an obstacle. The camera was used to capture images from the environment to sense the pathway condition. The line laser was used in combination with camera to recognize an obstacle...
Multiple sclerosis (MS) is a disease of the central nervous system (CNS), it is inflammation or decay in a myelin's substance (Demyelination). The causes of the disease is unknown yet, but it is believed to be caused by a combination of many genetic and environmental factors including: geographical distribution (i e less spread closer to the equator), and hereditary reasons. Currently, the diagnosis...
This paper presents a method for automatic segmentation of nuclei in phase-contrast images using the intensity, convexity and texture of the nuclei. The proposed method consists of three main stages: preprocessing, -maxima transformation-based marker controlled watershed segmentation (-TMC), and texture analysis. In the preprocessing stage, a top-hat filter is used to increase the contrast and suppress...
A good model of object shape is essential in applications such as segmentation, object detection, inpainting and graphics. For example, when performing segmentation, local constraints on the shape can help where the object boundary is noisy or unclear, and global constraints can resolve ambiguities where background clutter looks similar to part of the object. In general, the stronger the model of...
Information of the urban road areas for resource management, security monitoring, urban development and Geographic Information System (GIS) is changing with the growing world. Satellite image provides useful data that is extracted from satellite image of the urban area. Automatic extraction of the road intersections from the urban areas has been a challenging topic because the high resolution satellite...
This paper deals with segmentation of dermatological OCT images. Classic image segmentation techniques fail to produce accurate results due to the wide presence of speckle. We propose using speckle as source of information in the segmentation process. Different statistical models are analyzed in terms of their ability to differentiate skin layers. The local speckle parameters are used as a features-vector...
This paper describes the implementation of fuzzy based Handwriting Recognition (HR) system in VHDL. Key motivation of the design is to reduce computational complexity and performance enhancement. Fuzzy intelligent technique is used to tackle inherent ambiguities in different handwriting recognition. This system is capable of recognizing handwritten characters such as one segment, distinguish characters...
There is a growing concern over the adverse health effects of exposure to high concentration of mould spores in the indoor environments. Copious epidemiological studies have shown a direct relationship between the exposure to indoor mould and several adverse health effects. The phenomenon of Sick building syndrome (SBS) and Building Related Illness (BRI) have also been attributed to moulds exposure...
Although some major advances have been made in text searching; only preliminary work has been done in image search. The field of Image search is rooted in Artificial intelligence, digital signal processing, statistics, natural language understanding, databases, psychology, computer vision, and pattern recognition. However none of these fields can solve the problem of image search alone but the solution...
