https://community.intel.com/t5/Intel-Integrated-Performance/Thresholding-YUV/m-p/876943#M9643 Hi everybody, I'm a beginner in Computer Vision and I was told I should use YUV format to work with real environment images to detect specific objects. I've managed to read an RGB image and convert to YUV format and also separate the Y, U and V channels... but that's as far as I've got with IPP functions. I would like to have some help on how to apply a threshold to my YUV image given a specific pair of values for U and V... since luminance is suppossed to be avoided. An also, how should I read the U and V values of my images?<BR />Thanks and regards,<BR />Boris<BR /> Fri, 06 Jun 2008 12:50:11 GMT apolo74 2008-06-06T12:50:11Z https://community.intel.com/t5/Intel-Integrated-Performance/Thresholding-YUV/m-p/876943#M9643 Hi everybody, I'm a beginner in Computer Vision and I was told I should use YUV format to work with real environment images to detect specific objects.

For the computer vision domain you might be interested to take a look on <A href="http://www.intel.com/technology/computing/opencv">Intel OpenCV</A> library.</P> <P>Regards,<BR /> Vladimir</P> Tue, 05 Aug 2008 11:26:12 GMT https://community.intel.com/t5/Intel-Integrated-Performance/Thresholding-YUV/m-p/876944#M9644 Vladimir_Dudnik 2008-08-05T11:26:12Z
