See my attached demo where I use the radon transform to find the mean angle of an image by looking for the maximum projection value and then use imrotate() to rotate the image.

Thank you for the reply sir.

This is the output i'm getting.I can see that image itself is rotated which i don't need.I want the line which is slant to be rotated.How do i achieve that sir?

[Image Analyst]

Then just take all the dark pixels and fit them to a line and get the angle of the line and call imrotate to reverse the angle. See attached m-file.

Thank you so much sir :)

Looks like it would be a part of a larger script that should work. My Crystal Ball Toolbox trial expired so I can no longer see your code or error messages or images. Read this.

Dear Sir it works fine when the number of the text line is only one but failed when the number of text lines is more than one!!!what can i do to handle it?

Extract one line at a time and then do it.
