By Year By Research Group | This paper presents a survey and a comparative evaluation of recent techniques for moving cast shadow detection. We identify shadow removal as a critical step for improving object detection and tracking. The survey covers methods published during the last... In this paper, we propose a novel Patch Geodesic Distance (PGD) to transform the texture map of an object through its shape data for robust 2.5D object recognition. Local geodesic paths within patches and global geodesic paths for patches are combined in ... Video surveillance systems using Closed Circuit Television (CCTV) cameras, is one of the fastest growing areas in the field of security technologies. However, the existing video surveillance systems are still not at a stage where they can be used for ... Colony counting is a procedure used in microbiology laboratories for food quality monitoring, environmental management, etc. Its purpose is to detect the level of contamination due to the presence and growth of bacteria, yeasts and molds in a given ... We present a novel approach to landing and docking using time-to-contact estimates taken from optical flow divergence. Previous approaches have considered the use of optical flow for docking or landing, however, there exists no strategy that works for... A convenient way of analysing Riemannian manifolds is to embed them in Euclidean spaces. The dominant theme of embedding in the literature is to flatten the manifold through the use of tangent spaces. This school of thought is not free of drawbacks. For ... Face retrieval has received much attention in recent years. This paper comparatively studied five feature description methods for face representation, including Local Binary Pattern (LBP), Gabor feature, Gray Level Co-occurrence Matrices (GLCM), Pyramid ... In this paper we detail a system for creating object detectors which meet the extreme demands of real world traffic sign detection applications such as GPS map making and real-time in-car traffic sign detection. Detector requirements are designed to ... Indirect Immunofluorescence (IIF) on Human epithelial (HEp-2) cells test has been the golden standard for identifying the presence of Anti-Nuclear Antibodies (ANA) due to its high sensitivity and the large range of antigens that can be detected. ... |
