# ComfyUI-Image-Filters

Image filtering nodes for ComfyUI

Two install batch files are provided, install.bat which only installs requirements, and import_error_install.bat, which uninstalls all versions of opencv-python before reinstalling only the correct version, opencv-contrib-python (use this if you get import errors relating to opencv or cv2, which are caused by having multiple versions or the wrong version of opencv installed)

## Enhance Detail

Increase or decrease details in an image or batch of images using a guided filter (as opposed to the typical gaussian blur used by most sharpening filters)

## Guided Filter Alpha

Use a guided filter to feather edges of a mask based on RGB colors. Works best with a strong color separation between FG and BG.

## Remap Range

Fits the color range of an image to a new blackpoint and whitepoint (clamped). Useful for clamping or thresholding soft masks.

- alpha clean
- bilateral filter image for single frame denoise
- temporal bilateral filter for video denoise
