Next: NOMALIZE THE IMAGE
From: Samiov on 24 May 2010 06:40 Hi all, I wrote this code, that extracts the coordinates of 3 pixels, that allow me too crop the image. I thought it will be working but not. How to extract the first three points and quit the loops and don't have to cover the rest of the image if I obtain the first 'y2'. I put the statement break; in the last loop but the code returns: " ??? Undefined function or variable 'y2' ". and covers the rest of the image. Here's the original image and another image that explains by steps what I want to do... ---> http://drop.io/mqlwmho#- -------------------------------------------------------------- clear all, close all; clc; I = im2bw(imread('Ax.jpg')); imshow(I) [row col] = size(I); for jj = 1:col for ii = row:-1:1 if I(ii,jj) == 1; x1 = ii; y1 = jj; for kk = x1-1:-1:1 if I(kk,y1) == 1 && I(kk+1,y1) == 0; x2 = kk+1; for mm = y1+1:col if I(x1,mm) == 1 && I(x1,mm-1) == 0; y2 = mm-1; break; end end end end end end end I1 = I(x2:x1,y1:y2); figure, imshow(I1);

Well, the old saw of "failure to plan on your part..." comes to mind. Re: the question, from the documentation... help break .... > In nested loops, BREAK exits from the innermost loop only. .... You need a flag or other structure to get out of the rest of the nesting... --

Sit down. Take a deep breath. Hold your breath and count slowly to 5. Exhale. Take another deep breath. Hold your breath and count slowly to 5. Exhale. Take one more deep breath. You know the drill; hold the breath for a 5 count. Exhale. Now, without using ANY code and without using ANY images, explain what you're trying to do. We get that you're trying to crop an image -- explain IN WORDS how you determine the region to crop. Worry about converting it into code later; for right now just get the explanation of your goal written down clearly. [In most cases, you're going to need to do this step anyway to explain your work to one or more of your boss/teacher/professor/thesis or dissertation advisor/grant committee/colleagues, so don't think of this as wasted effort.] -- Steve Lord slord(a)mathworks.com comp.soft-sys.matlab (CSSM) FAQ: http://matlabwiki.mathworks.com/MATLAB_FAQ To contact Technical Support use the Contact Us link on http://www.mathworks.com |
