Web20 de nov. de 2024 · While doing some performance comparisons between cv::Mat and cv::UMat (OpenCL), I noticed that OpenCL was taking a lot longer (8x) when performing color conversions from YUV to BGR or RGB. I compared my benchmarking code to the perf tests, and I was not populating the optional dstCn parameter in my calls to cv::cvtColor(). WebYUYV is YUV 4:2:2, a weird term that says: "for a HxW image, Y is saved at full res, U and V are downsampled horizontally, and the bytes of UINT8 are stored in this order YUYVYUYVYUYV...". So it is in fact a 3 channel image, but 1 channel is bigger. So you can consider it's a 2 channel images: Y, and UV that are stored in an interleaved fashion.
