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
## Nodes
### Alpha Clean
Clean up holes and near-solid areas in a matte.
## Blur Image (Fast)
### Alpha Matte
Takes an image and alpha or trimap, and refines the edges with closed-form matting. Optionally extracts the foreground and background colors as well. Good for cleaning up SAM segments or hand drawn masks.

### Blur Image (Fast)
Blurs images using opencv gaussian blur, which is >100x faster than comfy image blur. Supports larger blur radius, and separate x/y controls.
## Blur Mask (Fast)
### Blur Mask (Fast)
Same as Blur Image (Fast) but for masks instead of images.
## Dilate/Erode Mask
### Dilate/Erode Mask
Dilate or erode masks, with either a box or circle filter.
## Enhance Detail
### 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
### Guided Filter Alpha
Use a guided filter to feather edges of a matte based on similar RGB colors. Works best with a strong color separation between FG and BG.

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