Image Enhancement

Select a filter from the list below.

Icon Name Description / Applications Modules
AutoAdjustColors

Adjusts image colors by stretching each channel separately.

FoundationLite
EqualizeImageHistogram

Maps image pixels to new values to achieve uniform distribution of intensities in the range (0, 255).

FoundationLite
ExpaintImage_Bornemann

Speculatively sets pixel values outside of a region using the fast marching method and coherence analysis.

FoundationPro
ExpaintImage_Telea

Speculatively sets pixel values outside of a region using the fast marching method.

FoundationPro
InpaintImage

Fills in a region of an image with pixel values interpolated from the borders of the area.


Speculative setting of unknown (or unwanted) pixels. Usually used for preparing incomplete images for further processing.

FoundationPro
InpaintImage_Bornemann

Fills in a region of an image with pixel values interpolated from the borders of the area; uses fast marching method and coherence analysis.


Speculative setting of unknown (or unwanted) pixels. This version is giving the best results among reasonably fast traditional methods.

FoundationPro
InpaintImage_Telea

Fills in a region of an image with pixel values interpolated from the borders of the area; uses fast marching method.


Speculative setting of unknown (or unwanted) pixels. This version is trying to do this better than with simple interpolation.

FoundationPro
NormalizeImage

Rescales an image linearly, so that its minimum becomes inNewMinimum and the maximum of the remaining pixels becomes inNewMaximum.


Aims at better using the image's dynamic range to represent an interesting subset of pixel values.

FoundationLite
NormalizeLocalBrightness_Gauss

Normalizes local brightness of the image. Internally uses Gauss smoothing.


Compensates uneven illumination.

FoundationBasic
NormalizeLocalBrightness_Mean

Normalizes local brightness of the image. Internally uses Mean smoothing.


Compensates uneven illumination.

FoundationBasic
NormalizeLocalContrast

Normalizes local contrast of the image using Wallis filter.

FoundationBasic
SharpenImage

Enhances contrast of an image so that it appears sharper.


Use this filter only to improve human perception, not to preprocess an image for analysis.
