Basic Examples  (2)

Find a color similar to pink in the image:

The image does not have a color similar to green:

Find a color similar to pink from a list of colors:

Scope  (4)

Find a color similar to pink in an image:

Look for multiple similarities:

Options  (3)

ColorCoverage  (1)

By default, an automatic minimum color coverage is used:

Require a minimum coverage level:

Specify a coverage interval:

DistanceFunction  (1)

By default, a perceptual color distance is used:

Use DistanceFunction to specify a different distance metric:

The new match has a closer luminance to the reference:

MaxColorDistance  (1)

By default, only colors close to the target color are returned:

Use MaxColorDistance to specify a custom threshold:

Use MaxColorDistanceInfinity to find the closest color:

Applications  (3)

Perform a foreground-background segmentation based on the color of the background:

The image seems to contain blue, but the actual pixel values are very far from it:

Find the matching blue in the image and use it to perform the segmentation:

Transform a color palette using colors from a natural image:

Select images based on the presence of a color:
