/* Assume p_rgb is a pointer that points to an image with shape (width, height, channel) */
LiteMat lite_mat_src(width, height, channel, (void *)p_rgb, LDataType::UINT8);
std::vector<LiteMat> lite_mat_dst;

/* Extract all channels of image */
Split(lite_mat_src, lite_mat_dst);

/* Merge all channels to an image */
LiteMat lite_mat_dst2;
Merge(lite_mat_dst, lite_mat_dst2);

Parameters

• mv – [in] Single channel data.

• dst – [in] Output image data.
