Error while evaluating UIControl Callback..

You create 2 vectors x,y with the length of rows/cloumns of your image, then you try to index Rimage(x+1,y+1) (which has the size of your image) in several cases. Thats why you get the Index exceeds matrix dimension error.

The second error is more of a synthax error, try

Xmin=get(handles.Xmin);
Xmax=get(handles.Xmax);

still getting the same errors

[Dennis]

What did you do to resolve your first problem?

[khushboo chhikara]

Nothing !! The errors are still same .. i have tried changing my image too !!

I cannot find out, which is the line 1132. It is not useful to post such a huge code (without a proper formatting! Please read How to format code) and let the readers count lines to find the failing code.

I guess the problem is caused by something like this:

[rows columns] = size(Image);
Rimage = Image;
for y = 1:columns
  for x = 1:rows
    if (Rimage(x, y+1)==th1) 

Now you try to process Rimage(x, y+1), when y=columns. Such an element does not exist, because Rimage does not have columns+1 columns.

You can use the debugger to check this. Type in the command window:

dbstop if error

Then run the code again until Matlab stops at the problem. Now check the values and sizes of the variables used in this line.
