ImageDev

Deblur2d

Enhances contrast and removes blur from a two-dimensional image.

Access to parameter description

For an introduction to image filters: see section Images Filtering.

This algorithm provides contrast enhancement and removes blur. It improves the boundaries of the different objects. The principle is to subtract from the image its own Laplacian.

A sharpening factor parameter controls the filter strength. The higher it is, the more sharpened the edges are and the more noise is revealed.

Note: The output image type is upgraded according to the Image type basic rule.
