Web5 de jul. de 2024 · opencv solarflarefx July 4, 2024, 10:42pm 1 Description Normally when I work with TensorRT, I have been storing data in linear CUDA memory and passing the pointer to the deserialized TensorRT engine. For example (assume “gpuTensorInput” and “gpuTensorOutput” are pointers to CUDA memory):
OpenCV reads an image in NCHW format (Number of samples x Channels x Height x Width), I need to convert it to NHWC format (move 2nd dimension of array to last). Is there an efficient way to convert from NCHW to NHWC in C++? I can do this with a 3 for loops, but obviously this is not efficient at all.
