| Abstract(in English) | In re-size (scaling) of a picture, a directional adaptive processing which realizes an improvement of subjective picture quality with a reduction of jaggy is discussed. In this processing, the clustering to change the processing by area type and the directional adaptive processing at edge area are applied. Although the authors had used the operators to detect 12 directions, two times magnification was realized to prevent the complexity of the reference pixel. In this paper, we study the 12 directional adaptive interpolation with four times magnification. In the expanding with high magnification, the direction adaptation is more effective, because jaggies are remarkable. The pixels used in interpolation are the original pixel and interpolated pixel which were made by one dimensional 8 tap filter. The pixels which are not nearest are used for the directions close to 0 or 90 degree. Nearest pixels are used for 45 or close degree. PSNR and enlarged picture show good results. |
