Improvements Based on the Harris Algorithm
Corner detection is a fundamental step in image processing, and it takes an important role in target tracking, image stitching and three-dimension reconstruction. Harris algorithm is widely used in corner detection for simple calculation and its detection result is not affected by image rotation and light intensity changes. Harris algorithm uses integral differential mask to extract the image g...
متن کاملAn Indoor Mobile Visual Localization Algorithm Based On Harris-Sift
Through the installation of a monocular vision sensor on a target and shooting sequence images of the floor, combined with the characteristics of the sequence images, an indoor mobile visual localization algorithm based on Harris-SIFT is proposed. The algorithm is first to establish first-order DOG scale space of sequence images of the floor, to extract feature points in each layer images of DO...
متن کاملParts Shape Recognition Based on Improved Harris Corner Detection Algorithm
Harris corner detection algorithm called Harris corner detector is a very effective corner algorithm for gray-scale images. The corners extracted by Harris corner detector are stable, reliable, homogeneous and reasonable. However, it has own inevitable limitations. For the shape recognition of parts, an improved Harris corner detector is proposed in this paper. Based on the analysis of Harris c...
متن کاملCrowd Density Estimation based on Improved Harris & OPTICS Algorithm
In this paper, we propose a method to estimate crowd density using improved Harris and Optics Algorithms. We pre-processed the raw images at first and the corner features of the crowd were detected by the improved Harris algorithm, then the formed density point data were used to analyze the corner characters of crowd density by the optics density clustering theory. This theory is related to the...
متن کاملAn Eye Feature Extraction Based on Harris Algorithm
In order to improve the recognition rate of the facial recognition system and the efficiency of the algorithm, a method based on Harris algorithm and changes of threshold to extract eye contour automatically is proposed. This method uses the idea of minimum extremal region. It makes use of the dynamic change of threshold form low to high. After location the eye area initially, the location of t...
