Empirical studies show that ippiTrueDistanceTransform_8u32f_C1R caps the maximum distance value at 1000.0. Is this an actual limitation to the routine or am I missing something? My expectation would be that the max value would be constrained by the data type (i.e. IPP_MAXABS_32F). Howeve, the value is obviously limited by memory contraints on the allowable image sizes.
My test consisted of an nxn image with the center pixel set to zero and the rest filled with ones. With n = 1600, all pixels beyond the 1000 pixel distance to the closest feature pixel are set to 1000.
Thanks for any input,
Bob
