Or should I use FloodFill to fill each connected region with a label?<BR /> Thu, 05 Oct 2006 03:20:47 GMT joechong 2006-10-05T03:20:47Z https://community.intel.com/t5/Intel-Integrated-Performance/Labelling-connected-regions/m-p/907702#M13742 Is there a function to label connected regions?

FloodFill_Range and FloodFill_Grad treat as a region a set of pixels in the interval or a set of pixels with restricted gradient. I think it is not just what ask.</P> <P>If connected regions are connected sets of neighboring non-zero pixels you can use ippiLabelMarkers_8u_C1IR function that assigns the same unique value from [1,254] to all pixels of different connected components. This function is included to IPP 5.2 Beta.</P> <P>Thanks,</P> <P>Alexander<FONT face="Courier" size="2"></FONT></P> <P></P> Thu, 12 Oct 2006 21:35:48 GMT https://community.intel.com/t5/Intel-Integrated-Performance/Labelling-connected-regions/m-p/907703#M13743 Intel_C_Intel 2006-10-12T21:35:48Z
