2017-06-09 04:51:49 -0600	asked a question	Runtime Efficiency of colorSpace conversion from BGR I was profiling cvtColor (opencv 3.2) for runtime efficiency. For an image of size 960x960, i got following results (in ms), for converting from BGR colorspace On PC (corei5 2.4 Ghz) `Gray(1.47668)<YUV(2.17967)<HLS(2.78009)<Lab(4.44801)<HSV_Full(5.02791)<Luv(5.27403)<HSV(5.54197)` On Raspi 3 `Gray(6.04175)<Lab(13.3423)<YUV(16.6426)<HSV_Full(19.5293)<HSV(21.5772)<HLS(32.6913)<Luv(63.4961)` Two things to know: 1) Why BGR2Luv conversion performace is so much different on PC and Raspi3 ? 2) Can we use LUT to improve the runtime Efficiency for colorSpace conversion ?
