[Octave-patch-tracker] [patch #9281] Image package: imsharpen

[Avinoam Kalma]

Follow-up Comment #3, patch #9281 (project octave):

Attached a better version, fixed according to comment#1 (Thanks Hartmut).

* I changed the tolerance of the failing test to 1, so it will not fail, but
still, there is 1 gray level difference between my results and Matlab
results.

* texinfo was fixed.
  
* Line 54: copy/paste error was fixed.

* I removed the clipping. I did not find differences after the removal.

* More example were added for uint8 input.

* Wrong indentation was fixed.

* I added more tests for few values of "Amount". I hope it checks the Gaussian
size.


And more more problem: I have tried to change


 Lab = rgb2lab (I);


to


 Lab = rgb2lab (double(I));

 
It fixed one test, but in made other test to fail. Any idea about this?

Please review the attached new version. Thanks.
