实现相位编组的算法I=imread( bbb.jpg ) x=rgb2gray(I) x=double(x) gradephase(x)-I=imread( bbb.jpg ) x=rgb2gray(I) x=double(x) gradephase(x)

Igray = rgb2gray(I) Ibw = im2bw(Igray,graythresh(Igray)) Iedge = edge(uint8(Ibw)) se = strel( square ,3) Iedge2 = imdilate(Iedge, se) Ifill= imfill(Iedge2, holes ) [Ilabel num] = bwlabel(Ifill) Iprops = r

The morphology operation to read the image and convert the rgb2gray, and convert in to the binaring the input image.Adding the binary noise to the image next the input image to make text in white and background in black. Next do the two operation d
