InpaintImage_Telea

Advanced

Module: FoundationPro

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

Applications

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

Description

This filter inpaint a region of an image using the fast marching method. It is a simper version of InpaintImage_Bornemann in that it only uses the shape of the inpainting region and doesn't use structural information of the image.

Each inpainted pixel is filled with a color calculated as a weighted average of all already known (i.e. those outside of the inpainting range or those that were already) pixels withing a range specified by the parameter inRange. Using a higher range will result in smoother edges withing the inpainted region.

Examples

Comparison between low and high values of inRange. From the left: input, output with inRange = 4, output with inRange = 12

Errors

This filter can throw an exception to report error. Read how to deal with errors in Error Handling.

List of possible exceptions:

Error type Description
DomainError Expainting region (inRegionToExpaint) exceeds the image in InpaintImage_Telea.
DomainError No pixels available at the edge of inRegionToInpaint in InpaintImage_Telea.

Complexity Level

This filter is available on Advanced Complexity Level.

Filter Group

This filter is member of InpaintImage filter group.
