Color

Stretch Contrast

Scales the components of the buffer to be in the 0.0-1.0 range. This improves images that make poor use of the available contrast (little contrast, very dark, or very bright images).

Operation pads

This operation exposes the following data pads, defining how it receives, processes, and emits image data:

Input

Output

Operation properties

Keep colors

gboolean

Impact each channel with the same amount.
Default true

Non-linear components

gboolean

When set operate on gamma corrected values instead of linear RGB - acting like the old normalize filter in GIMP.
Default false

Simple Linear Iterative Clustering

Superpixels based on k-means clustering.

Stretch Contrast HSV

Scales the components of the buffer to be in the 0.0-1.0 range. This improves images that make poor use of the available contrast (little contrast, very dark, or very bright images). This version differs from Contrast Autostretch in that it works in HSV space, and preserves hue.
