Based on the analysis of the shadow zone and the padding methods of the Radon domain generated by circular cone-beam CT scanning,this paper proposes a shadow zone padding method by distance-weighted interpolation.

Research and Application of Region Filling and Real-Time Animation Generation;

An improved region filling inpainting method is proposed by using structure tensor that can successfully capture the local variations of an image.

present a region filling algorithm based on Fast Marching Method, which can be used in one color or gradient filling for both boundary-defined regions and interior-defined 4-connected regions.

A scanline algorithm for area filling with pushing span-ends has good efficiency but also a shortcoming that one class of special connected fields cann′t be filled completely by this algorithm .

This paper presents an improved scanline algorithm for area filling.

First,through two-value character distill,area fill,image minus to bubbles image,the bubbles brightness dots are obtained.

By analysing the file format, the GRAPHER boundary file (* bln) has been read out On this basis, using the boundary scanning method to determine the boundary of the filling zone and the picture composite method to create filling pattern, a geological plot filling system has been created and has been succesfully applied to computer plot processin
