Threshold segmentation and Complementary Similarity Measure plays an important role in the Optical Character Reader (OCR). Generally, threshold segmentation and matching are separated. One of some methods such as iterative method, ENT, OSTU and so on is applied to threshold segmentation. But in practice, these methods are adaptive to a restricted condition. When character is distorted by random...

A PCA based gait segmentation method is proposed. Background images are used for PCA training. PCA reconstruction, recursive error compensation and single threshold based method is put forward for gait segmentation. Single threshold based method has the same gait segmentation ability as classical adaptive threshold based method, and the former is faster in implementation than the later. Propose...
