Description

in openCV version 2.3, when using bilateralFilter with a cv::Mat of type CV_32FC1 in which some entries are nan (common for sensor-generated images where "zero" could count as a valid measurement) a segmentation fault occurs at runtime. An exception would be better...

cv::blur does not segfault on the same images (but might be doing other strange things...)

thanks for the report. In SVN, r8185 I added function patchNaNs that replaces NaNs with the specified value. This function is now called from within bilateralFilter (without affecting the input image), so the exception should not happen anymore.
