20110274314 | REAL-TIME CLOTHING RECOGNITION IN SURVEILLANCE VIDEOS - Systems and methods are disclosed to recognize clothing from videos by detecting and tracking a human; performing face alignment and occlusal detection; and performing age and gender estimation, skin area extraction, and clothing segmentation to a linear support vector machine (SVM) to recognize clothing worn by the human. | 2011-11-10 |
20110274315 | METHOD, DEVICE, AND COMPUTER-READABLE MEDIUM OF OBJECT DETECTION - Disclosed are an object detection method and an object detection device. The object detection method comprises a step of obtaining plural detection results of a current frame according to plural object detection methods; a step of setting initial probabilities of the plural detection results of the current frame; a step of calculating a movement frequency distribution diagram representing movement frequencies of respective pixels in the current frame; a step of obtaining detection results of a previous frame; a step of updating the probabilities of the plural detection results of the current frame; and a step of determining a final list of detected objects based on the updated probabilities of the plural detection results of the current frame. | 2011-11-10 |
20110274316 | METHOD AND APPARATUS FOR RECOGNIZING LOCATION OF USER - A method of recognizing a location of a user including detecting the user's two eyes and mouth of their face is provided, which includes calculating a ratio of a distance between the two eyes to a distance between a middle point of the two eyes and the mouth, calculating a rotation angle of the face according to the ratio, and detecting a distance between the face and the camera based on the rotation angle. | 2011-11-10 |
20110274317 | MATCHING WEIGHT INFORMATION EXTRACTION DEVICE - The matching weight information extraction device includes a matching weight information extraction unit. The matching weight information extraction unit analyzes a change in a time direction of at least either an input video or features of a plurality of dimensions extracted from the video, in association with the dimensions. Further, the matching weight information extraction unit calculates weight information to be used for matching for each of the dimensions as matching weight information, according to a degree of the change in the time direction. | 2011-11-10 |
