Opencv nchw to nhwc
Webnchw 中,c 排列在外层,每个通道内像素紧挨在一起,即 'rrrrrrggggggbbbbbb' 这种形式。 nhwc 格式,c 排列在最内层,多个通道对应空间位置的像素紧挨在一起,即 'rgbrgbrgbrgbrgbrgb' 这种形式。 如果我们需要对图像做彩色转灰度计算,nchw 计算过程如 … Web24 de out. de 2024 · NVES: TensorRT’s C++ API input and output tensors are in NCHW format. This didn’t seem to be the case for me. I am using a network configured as NHWC. Despite that, I did input data in NCHW format as you mentioned was a requirement. However, the output data I am copying out via TensorRT’s C++ API was in NHWC format.

A slower alternative would be to use 3 calls to cudaMemcpy2D to copy the data from host to device, one call per plane.
