An image degradation model has been established and the factors affecting radiant image blurring are analyzed on the basis of motion imaging relations,signal.

By analysis on image degradation of X-ray imaging system, the restoration method of inverse filtering was introduced and an approximate restoration algorithm was proposed.

Image gray degradation and geometric transform are treated as image degradation,and image degradation invariant is proposed,and the construction of degradation invariant is analyzed.

In this paper the influences of imaging system on static image are discussed and modeling of image degradation isestablished (especially the transfer function) taking the transfer functions of the component parts of the system into consideration.

Accelerate factor analysis for power law degradation model under the condition of small sampling test;

Computed tomography image edge degradation model and its application to image size measurement

The comparison between ADT and ALT technologies,related background,degradation models,data analysis methods and design and optimization of ADT are described.

Considering that the traditional analytical positioning apparatus can′t be used to localize the target in video image obtained from universal air detection platform,based on the image digitalizing this paper proposes a new method of localizing the target by means of setting up the degenerate model of collinearity condition equation.
