This research describes the edge extraction as a preceding process which realizes high resolution and scalable image compression by function approximation. We propose for fundus photograph
asked for especially high resolution in a medical picture. If single thresholding is performed, the area which a blood vessel is not extracted in the bad domain of contrast will come out. Then, the filter which solves this problem by determining threshold locally was developed. As a result of comparison between the edge extraction by the Sobel filter with the highest accuracy and the proposed method, it has checked that the blood vessel could be extracted also in the bad domain of the contrast which cannot be extracted in the Sobel filter. By improvement of edge extraction method, the possibility of the high resolution and scalable compressing method was suggested. |
