# ComfyUI-Image-Filters
Image filtering nodes for ComfyUI
Image and matte 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)

## Alpha Clean
Clean up holes and near-solid areas in a matte.
## 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.
