WebMatrix multiplication is where two matrices are multiplied directly. This operation multiplies matrix A of size [a x b] with matrix B of size [b x c] to produce matrix C of size [a x c]. In OpenCV it is achieved using the simple * operator: C = A * B. Element-wise multiplication is where each pixel in the output matrix is formed by multiplying ... WebLet A and B be two matrices of same dimension. The operators +, -, /, *, ^ when used with matrices of same dimension perform the required operations on the corresponding elements of the matrices and return a new matrix of the same dimension. These operations are usually referred to as element-wise operations.

WebAug 12, 2015 · It seems you are doing matrix-multiplications for each slice along the first axis. For the same, you can use np.einsum like so - np.einsum('ijk,ikl->ijl',A,B) We can also use np.matmul-np.matmul(A,B) On Python 3.x, this matmul operation simplifies with @ operator-A @ B Benchmarking. Approaches - WebApr 26, 2014 · See answer posted by @marol for code example. In this solution the main overhead is copy of data. That means extra time and space. This is reasonable solution if you are going to perform multiple operations with both images. But if all you need is simple multiplication it won't be very effective. 3) Use workarounds.
