The control circuits and software systems for image scanning and processing were introduced.

We defined two species of index to measure the stability of the image scanning ways.

This paper defines two kinds of measurement parameter to describe the stability of the image scanning data for the online traffic image.

A digital method for the correction of geometric distortion in scanned image;

Study on improving success rate of edge detection for scanned image of bacteriostatic ring

This paper presents a new algorithm of adherence separation of linear features to scanned image.

So it is necessary to know the effect of hydration films on scanning images.

Aimed at that ultrasonic B scan image of planar defect was degraded because of contaminated by noise,the degraded image was en- hancement processed by using wavelet analysis.

Aimed to the testing problem of brazing quality of arc surface electric contact,its ultrasonic C-scan image model was built firstly.

To improve efficiency of flaw component labeling,assistant table was used to save equivalent label at the first scanning,after some disposal processes to assistant table,such as wiping off repeated records,equipollence analysis,adding records and redistributing labels,C-scan image elements was relabeled at the second scanning,applications testify the validity of the method.

A method for restoration of ultrasonic C-scan images is presented by using a radial basis function network.
