Method Details

watersheds

public static BufferedImage watersheds(GrayS32 segments,
 @Nullable
 @Nullable BufferedImage output,
 int radius)

Sets the pixels of each watershed as red in the output image. Watersheds have a value of 0

Parameters:

segments - Conversion from pixel to region

output - Storage for output image. Can be null.

radius - Thickness of watershed. 0 is 1 pixel wide. 1 is 3 pixels wide.

Returns:

Output image.

regions

public static BufferedImage regions(GrayS32 pixelToRegion,
 int numRegions,
 @Nullable
 @Nullable BufferedImage output)

Draws each region with a random color

Parameters:

pixelToRegion - Conversion from pixel to region

numRegions - Total number of regions.

output - Storage for output image. Can be null.

Returns:

Output image.

regionsColor

public static BufferedImage regionsColor(GrayS32 pixelToRegion,
 DogArray<float[]> segmentColor,
 @Nullable
 @Nullable BufferedImage output)

Draws each region using the provided color

Parameters:

pixelToRegion - Conversion from pixel to region

segmentColor - Color of each region

output - Storage for output image. Can be null.

Returns:

Output image.

regionBorders

public static BufferedImage regionBorders(GrayS32 pixelToRegion,
 int borderColor,
 @Nullable
 @Nullable BufferedImage output)

Draws border pixels of each region using the specified color.

Parameters:

pixelToRegion - Conversion from pixel to region

borderColor - RGB value of border pixel

output - Storage for output image. Can be null.

Returns:

Output image.
