Saturation

Slot Usage: 0

Overview

Saturation node increases or decreases color intensity in the input image by shifting the saturation channel of the HSV color space.

Use this node to make colors more vivid for color-detection pipelines, or to desaturate images before greyscale-based analysis.

Input

Input Image

image required

The image frame to adjust. Connect this to a camera or upstream processing output.

Saturation

integer required

Saturation offset added to the HSV saturation channel.

Range: -255 to 255
Default: 0

  • 0 — no change.
  • Positive values increase color vividness.
  • Negative values reduce saturation; at -255 the image is fully desaturated (greyscale).
