Corner detection in color images through a multiscale combination of end-stopped cortical cells
We assess the corner-detection capabilities of a model for endstopped cells in the visual cortex (Heitger et al., 1992). The responses of one of these cells alone can not account for the percept of a corner. This shortcoming can be greatly alleviated by a combination over several scales. The resulting corner detection method can deal with high frequency texture, low contrast, and rounded corner...
متن کاملContour-Based Corner Detection and Classification by Using Mean Projection Transform
Image corner detection is a fundamental task in computer vision. Many applications require reliable detectors to accurately detect corner points, commonly achieved by using image contour information. The curvature definition is sensitive to local variation and edge aliasing, and available smoothing methods are not sufficient to address these problems properly. Hence, we propose Mean Projection ...
متن کاملAccurate Corner Detection Methods using Two Step Approach
: Many image features are proved to be good candidates for recognition. Among them are edges, lines, corners, junctions or interest points in general. Importance of corner detection in digital images is increasing with increasing work in computer vision in imagery. One of the most promising techniques is the one based on Harris corner detection method. This work describes different approaches t...
متن کاملImage Corner Detection Based on Curvature Scale Space and Adaptive Thresholding
Corner detection or the more general terminology interest point detection is an approach used within computer vision systems to extract certain kinds of features and infer the contents of an image. Corner detection is frequently used in motion detection, image matching, tracking, image mosaicing, panorama stitching, 3D modelling and object recognition. It is difficult to detect both fine and co...
متن کاملLow Complexity Corner Detector Using CUDA for Multimedia Applications
High speed feature detection is a requirement for many real-time multimedia and computer vision applications. In previous work, the Harris and KLT algorithms were redesigned to increase the performance by reducing the algorithmic complexity, resulting in the Low Complexity Corner Detector algorithm. To attain further speedup, this paper proposes the implementation of this low complexity corner ...
