Automatically detect and eliminate hot pixels.

Hot pixels are pixels which have failed to record a light level correctly. Detected hot pixels are replaced by an average of their neighbors.

module controls

How strong a pixel’s value needs to deviate from that of its neighbors to be regarded as a hot pixel.
The blending strength of the hot pixels with their surrounding.
detect by 3 neighbours
Extend the detection of hot pixels – regard a pixel as hot if a minimum of only three (instead of four) neighbor pixels deviate by more than the threshold level.
mark fixed pixels
Visually mark the corrected pixels on the image and display a count of hot pixels that have been fixed.
