Simulation experimental results show this method achieves the fact that the recognition performance under low face image resolution is almost the same as that under high one,and both recognition rate and efficiency are considered.

The effect of sampling step on the resolution of ultrasonic C-scan image was studied, and an edge adaptive image interpolation method based on the local covariance feature was presented to improve the C-scan image resolution.

In view of the application of onboard video image in the battle field,the special qualification to image resolution and frame rate is analyzed as onboard image is compressed.

Novel algorithm for estimation of intrinsic dimension in human face images;

Improved method of human face image edge detection on DM642

By using and recognizing the geometric regional buildup method to pretreat the human face image and using repository method to pick - up characters of the human face image, a simple and convenient method called repository and regional dealing with is put forward in this paper.
