WebAs follows: ① In opencv, the graph format is HWC, and the rest are CHW, so transfer ( (2,0,1)) ② IMG [:,:,:: – 1] corresponds to h, W and C. The color map is 3 channels, that is, C is 3 layers. Opencv corresponds to BGR, so through channel C:: – 1 is to convert BGR to RGB. WebThis layer performs a correlation operation between 3-dimensional filter with a 4-dimensional tensor to produce another 4-dimensional tensor. An optional bias argument is supported, which adds a per-channel constant to each value in the output. ... so to permute from CHW order to HWC order, the required permutation is [1, 2, 0], and to permute ...
