bool mindspore::dataset::Multiply(const LiteMat &src_a, const LiteMat &src_b, LiteMat *dst)
Given image A and image B and calculate the product of them (A * B). This is an element by element operation by multiplying corresponding elements of inputs.
- Parameters
src_a – [in] Input image data.
src_b – [in] Input image data.
dst – [in] The product of input images.
- Returns
Return true if transform successfully.
