This is the correct section
Possibly this:
1) High Pass, much used for sharpening an image see: https://docs.gimp.org/en/gimp-filter-high-pass.html
2) Maximum and Minimum, a maybe since I do not use PS but..
Morphological Filters: Minimum and Maximum The most common morphological operations are minimum (also known as erosion) and maximum (dilation) filters.
So try: Filters -> Generic -> Erode or Filters -> Generic -> Dilate
3) Offset
So try: Layer -> Transform -> Offset
