Many non-pornographic images containing large exposure of skin area or approximate skin-color area are prone to be detected as the pornographic images. This paper proposes a novel method based on AdaBoost algorithm for nipple detection of pornographic images. The AdaBoost algorithm has excellent performance in both detection accuracy and detection speed. The method extracts extended Haar-like features,...
The essay designs a target positioning and tracking system based on the binocular vision. According to the method of look-up compressed tables, image capture module transfers the digital image to HSV color space. Introduce a self-adaptive threshold segmentation algorithm based on the 3σ principle of control chart theory to recognize the target. Calculate the relative position to the target by the...
A new floating car data technology in Hefei has been developed that provides real-time traffic information within Hefei's two ring road. It is based on the collection of localisation data, speed, direction of travel and time information from GPS in vehicles that are being driven. The scope of the project is to development and creation of a Web-based data mart for the collection of FCD. The aim of...
Traditional level-set methods use gray level images as its main study objects. The basic idea is coupling image data and speed of the curve deformation, stopping the curve evolution on the edge of target, which requires a speed function to control the evolvement. However, traditional methods only set gray-scale gradient information as the stopping power of contour lines to define the velocity function,...
