Image Sharpen

Documentation

• Class name: ImageSharpen

• Category: image/postprocessing

• Output node: False

The ImageSharpen node enhances the clarity of an image by accentuating its edges and details. It applies a sharpening filter to the image, which can be adjusted in intensity and radius, thereby making the image appear more defined and crisp.

Input types

Field	Comfy dtype	Description
image	IMAGE	The input image to be sharpened. This parameter is crucial as it determines the base image on which the sharpening effect will be applied.
sharpen_radius	INT	Defines the radius of the sharpening effect. A larger radius means that more pixels around the edge will be affected, leading to a more pronounced sharpening effect.
sigma	FLOAT	Controls the spread of the sharpening effect. A higher sigma value results in a smoother transition at the edges, while a lower sigma makes the sharpening more localized.
alpha	FLOAT	Adjusts the intensity of the sharpening effect. Higher alpha values result in a stronger sharpening effect.

Output types

Field	Comfy dtype	Description
image	IMAGE	The sharpened image, with enhanced edges and details, ready for further processing or display.
