WebNov 24, 2024 · Depth-wise Separable Convolutions. Spatially Separable Convolutions. In images height and width are called spatial axes. The kernel that can be separated across spatial axes is called the spatially separable kernel. The kernel is broken into two smaller kernels and those kernels are multiplied sequentially with the input image to get the same ...
