ImageSharpen - ComfyUI Built-in Node Documentation

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.

Inputs

Field	Description	Data Type
`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.	`IMAGE`
`sharpen_radius`	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.	`INT`
`sigma`	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.	`FLOAT`
`alpha`	Adjusts the intensity of the sharpening effect. Higher alpha values result in a stronger sharpening effect.	`FLOAT`

Outputs

Field	Description	Data Type
`image`	The sharpened image, with enhanced edges and details, ready for further processing or display.	`IMAGE`
