Conference on visual communications and image processing 2004
作者: Lee, MS Shen, MY Kuo, CCJ Univ So Calif Dept Elect Engn Los Angeles CA 90089 USA
Several color matching algorithms are proposed to merge two or more video inputs of smaller sizes in to one single video output of a larger size with a wider field of view for the video mosaic application. The main ch... 详细信息

International Conference on Signal processing and communications (SPCOM)
作者: Srinivasan, M Annadurai, S Anna Univ Govt Coll Technol Coimbatore Tamil Nadu India
An image is often corrupted by additive gaussian noise during its acquisition and transmission. Denoising has to be performed on these images to retain the signal and to suppress the noise. Denoising can be performed ... 详细信息
