3d2c0ed97f Removed check on limits. A common use of HoughLines would be to restrict theta to be between a small negative number and a small positive number, e.g. -pi/16 to pi/16. This wasn't possible with the previous checks. 2015-03-13 17:04:13 -07:00

9811a739b0 Change gaussianBlur5x5 perf test epsilon 
Set it 1 instead of 0.001, as is already done in gaussianBlur3x3. That
will allow integer destination matrices that are not exactly the same,
but very close to the expected result, to pass the test.

In the unoptimized version of small symmetrical column filters, when we

should take into consideration that the anchor points in the middle
element.
