Intelligent Image Segmentation and Synthesis
With the rapid development of the e-commerce, shopping online has gradually become one of the most im-portant way of shopping in our life. But there are still some problems, such as size, color, quality and other is-sues. We can always find some comments that some clothes have color difference. The consumers...
Weighted Fusion of Multi-Featured of Gait Recognition Algorithm
Hui Wang, Taijun Li, Haoli Zhou, Zezhong Yang
Gait recognition has become one of the hottest directions in study of long-range identification. Joint angle feature is an important gait feature, but extracting joint angle feature using traditional skeleton model is too idealistic. Therefore, a method of extracting joint angle feature based on skeleton...
