Hi guys,

trying to use fcvMseru8 on grayscale data, but it's work strange - nothing found (on image contours exist). Is any special data format needed (YCbCr or etc)?

Yes the function fcvMseru8expects grayscale input image. If you can share the source image for which this function seems to behave unexpectedly, we can investigate whether it’s due to breakdown of algorithm or some other reason. 

Cheers,

Hi! Here the link bit.ly/MHixKh.

My parameters are:

unsigned int align = 16;
unsigned int channels = 1;
unsigned int delta = 1;
unsigned int minArea = 1;
unsigned int maxArea = widht * height;
float maxVariation = 0.5;
float minDiversity = 0.5;	
void* mserHandle;
unsigned int maxContours = 10;
unsigned int numContours = 0;
unsigned int* numPointsInContour = (unsigned int*) fcvMemAlloc(maxContours * sizeof(unsigned int), align);
unsigned int* pointsArray = (unsigned int*) fcvMemAlloc(maxContours * width * height * sizeof(unsigned int), align);
unsigned int dataStride = width * channels * sizeof(uint8_t);
