To resolve issues starting MATLAB on Mac OS X 10.10 (Yosemite) visit: http://www.mathworks.com/matlabcentral/answers/159016
I = imread('Image.jpg'); i = I(:,:,3); m = max(max(i)); [r c] = find(i ==m ); fid = fopen('lalit.txt','wt'); for j=1:length(r) fprintf(fid,'%f %f\n',r(j),c(j)); end fclose(fid);
in this text file min(r) = 1 and max(r) = 554..
for each r there is more than one value..
like, for each r =222, there is c = 231,419,421,422,424,425,426,427,428,429,430,431,432,433,434,438 so i want Z = round((max(c) + min(c))/2); = round((231 + 438)) = 335
and i want this for all r...
and then want to plot that values plot(z,r)
So, how to do this..?
