IEEE International conference on visual communications and image processing (VCIP)
作者: Zhang, Yongqin Liu, Jiaying Yang, Saboya Guo, Zongming Peking Univ Inst Comp Sci & Technol Beijing 100871 Peoples R China
The observed images are usually noisy due to data acquisition and transmission process. Therefore, image denoising is a necessary procedure prior to post-processing applications. The proposed algorithm exploits the se... 详细信息
