The Filter2D block convolves an image with the specified kernel.
Library
ComputerVision/Images/Filters
Description
The Filter2D applies a non-separable 2D linear filter to an image.
For 1D signals, you can use the Filter 2D block to filter images with various low-pass filters (LPF) and high-pass filters (HPF).
