Method Details

grayScaleImage

public static BufferedImage grayScaleImage(BufferedImage bufferedImage)

Gray scales a BufferedImage.

Parameters:

bufferedImage - The image to be converted.

Returns:

The original image as gray scale.

thresholdImage

public static BufferedImage thresholdImage(BufferedImage image,
 int threshold)

Converts an image to a binary one based on given threshold. A lower threshold will result in more of the image being completely white.

Parameters:

image - the bufferedimage to convert.

threshold - the threshold in [0,255]

Returns:

a new BufferedImage instance of TYPE_BYTE_GRAY with only 0'S and 255's

rescaleImage

public static BufferedImage rescaleImage(BufferedImage image,
 int targetHeight,
 int targetWidth)

To shrink the pixelcount in an image without changing its content.

Parameters:

image - The image to rescale.

targetHeight - The pixel hight it should have.

targetWidth - The pixel width it should have.

Returns:

A smaller version of the original image.
