Text is a vital feature in applications of computer vision. Traditional Chinese character recognition techniques are mainly based on optical character recognition (OCR), however, they can't obtain satisfactory results from images affected by complex circumstance, such as different viewpoint, scale changes, addition of noise and complex background.

In this paper, we study the effect of susceptible hosts movements on parasites invasion and host persistence and extinction. The results indicate that it is more easier for parasites to invade if increase the movement rate of susceptible hosts. But, reduce the chance of host extinction.
Diseases or some experimental factors may lead to the change of volume in a particular tissue, but it is difficult for physicians to identify these subtle changes visually. In this study, we designed and developed a computer-aided analysis software package for volume measurement of the local homogenous region on magnetic resonance (MR) images. The key algorithm integrated the threshold value method...
