Web10 de dez. de 2024 · 在嵌入式端进行CNN推理时,opencv中Mat数组数据组织格式为HWC,输入到推理框架中,需要转换为CHW格式,可以使用opencv中dnn模块的cv::dnn::blobFromImages或cv::dnn::blobFromImage函数进行转换,得到一个Mat数组,它的Mat.data的数据组织格式为NCHW,数据类型为float32,可以直接输入到推理框架中。 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.
