  1. work 小波轉換後,使用gaussian filter做hittorgam取max bin值作為二元化的分界點, 將圖改為僅0 1值 ANA細胞圖

  2. [cA,cH,cV,cD] = dwt2(y,'wname'); % wname:haar, db1,db2...db45, coif1,coif2...coif45, sym2,sym3...sym45, dmey, bior1.1, rbio1.1, wavelet

  3. s = imread('s.jpg'); y = rgb2gray(s); imwrite(y,'y.jpg')‏ [cA,cH,cV,cD] = dwt2(y,'haar');%haar小波轉換後為double a = uint8(cA); h = uint8(cH); v = uint8(cV); d = uint8(cD); imwrite(a,'a.jpg'); imwrite(h,'h.jpg'); imwrite(v,'v.jpg'); imwrite(d,'d.jpg'); wavelet haar

  4. 灰階

  5. 小波轉換

  6. haar轉換後gaussian filter

  7. x = 0:1:255; [a,b] = hist(g,x); % a=pixelvalue % b=grayvalue historgam

  8. historgam table
