How to convert a low-pass Gaussian filter to a high pass filter

Web27 nov. 2016 · 1 Answer Sorted by: 3 The simplest option is to remove the low-pass signal from the data. Just subtract the outcome of your code from the original image. This amounts to computing: I high = δ ∗ I − g ∗ I = ( δ − g) ∗ I. The term δ ∗ I corresponds to the convolution of a Dirac delta to the image, which is an invariant operation. Web2D Gaussian low pass filter can be expressed as: For the 2D Gaussian filter, the cutoff value used is the point at which H (u,v) decreases to 0.607 times its maximum value.
