Visual tracking algorithm based on robust PCA
Yue Chenchen, Hou Zhiqiang, Yu Wangsheng, Pu Lei, and Ma Sugang
At present, several mainstream algorithms using color name (CN) all adopt principal component analysis (PCA) to process the feature. However, PCA assumes that the noise of input data must obey Gaussian distribution, which is a conspicuous defect. Aim to address this problem, in this paper, we take robust principal comp

A hierarchical method for quick and automatic recognition of sunspots
Zhao Ziliang, Liu Jiazhen, Hu Zhen, Jia Yanhao, Wang Yue, Li Qingwei, Zhao Zeyang, and Liu Yangyi
The observation and recognition of sunspots is an important task of solar physics. By observing and analyzing sunspots, solar physicists are able to analyze and predict solar activities with higher accuracy. With the continuous progress of observation instruments, solar full-disk image data amount is also on a rapid gr

Despeckling for side-scan sonar images based on adaptive block-matching and 3D filtering
Chen Peng, CaiXuanwei, Zhao Dongdong, Liang Ronghua, and Guo Xinxin
Side-scan sonar (SSS) is an electronic device that utilizes the propagation characteristics of sound waves under water to complete underwater detection. Because the SSS produces images and maps according to the in-tensity of acoustic echo, speckle noise will be inevitably involved. A speckle denoising method based on b
