Faster Convolution with Separability Property in Multi-dimensional Signals
Topic: Digital image processing.
Consider a 2D signal (or impulse response of 2D filter) with rect-shaped.
This 2D rect signal is separable. It can be represented as dot-product of two independent 1D signals.
As well an impulse signal is also separable.
