How To Use Opencv With Cuda Support Python?

I found example of cuda accelerated opencv python code in official opencv github repository. test_cuda.py cuMat1 = cv.cuda_GpuMat() cuMat2 = cv.cuda_GpuMat() cuMat1.upload(npMat1)

Solution 1:

You should change like this.

cuMat1 = cv.cuda_GpuMat()
cuMat2 = cv.cuda_GpuMat()

npMat1_n = cv.cvtColor(npMat1, cv.COLOR_RGB2GRAY)
npMat2_n = cv.cvtColor(npMat2, cv.COLOR_RGB2GRAY)

cuMat1.upload(npMat1_n)
cuMat2.upload(npMat2_n)
