BasicLocalBinaryPattern

public BasicLocalBinaryPattern()

Method Detail

getPattern

public int[][] getPattern()

Get the pattern created during the last call to analyseImage(FImage).

Returns:

the pattern

calculateLBP

public static int[][] calculateLBP(FImage image)

Calculate the LBP for every pixel in the image. The returned array of LBP codes has the same dimensions as the image. Samples taken from outside the image bounds are assumed to have the value 0.

Parameters:

image - the image

Returns:

a 2d-array of the LBP codes for every pixel

calculateLBP

public static int calculateLBP(FImage image,
                               int x,
                               int y)

Calculate the basic LBP for a single point. The point must be within the image.

Parameters:

image - the image

x - the x-coordinate of the point

y - the y-coordinate of the point

Returns:

the LBP code

calculateLBP

public static int calculateLBP(FImage image,
                               Pixel point)

Calculate the basic LBP for a single point. The point must be within the image.

Parameters:

image - the image

point - the point

Returns:

the LBP code

analyseImage

public void analyseImage(FImage image)

Description copied from interface: ImageAnalyser

Analyse an image.

Specified by:

analyseImage in interface ImageAnalyser<FImage>

Parameters:

image - The image to process in place.
