1st International Conference on image Analysis and recognition, ICIAR 2004
作者: Peng, Ning-Song Yang, Jie Chen, Jia-Xin Institute of Image Processing and Pattern Recognition Shanghai Jiaotong University P.O. Box 104 1954 Huashan Road Shanghai200030 China Institute of Electronic and Information Henan University of Science and Technology Luoyang471039 China
In the case of tracking object changing in size, traditional mean-shift based algorithm always leads to poor localization owing to its unchanged kernel-bandwidth. To overcome this limitation, a novel kernel-bandwidth ... 详细信息
