This is the code i have written so far. i am using gradient vector flow(gvf) function. I = imread('taijitu main.jpg'); [R C]= size(I); cmap = rgb2hsv(I); luminance = hsv(3); [histIm,T]= histeq(luminance); [Gmag, Gdir]= imgradient(luminance,'roberts'); [u,v]= GVF([Gmag,Gdir],0.2,80); gvf = sqrt(u.^2 + v.^2); B = sort(I,'descend'); for i=1:R-1 for j=1:C-1 if gvf(i,j)> 0 I(i,j)=1; I=I+1; end end end
