Method Detail

mean_thresh

public int[] mean_thresh(int[] src,
                         int width,
                         int height,
                         int size,
                         int con)

Applies the adaptive thresholding operator to the specified image array using the mean function to find the threshold value

Parameters:

src - pixel array representing image to be thresholded

width - width of the image in pixels

height - height of the image in pixels

size - the size of the neigbourhood used in finding the threshold

con - the constant value subtracted from the mean

Returns:

a thresholded pixel array of the input image array

median_thresh

public int[] median_thresh(int[] src,
                           int width,
                           int height,
                           int size,
                           int con)

Applies the adaptive thresholding operator to the specified image array using the median function to find the threshold value

Parameters:

src - pixel array representing image to be thresholded

width - width of the image in pixels

height - height of the image in pixels

size - the size of the neigbourhood used in finding the threshold

con - the constant value subtracted from the median

Returns:

a thresholded pixel array of the input image array

meanMaxMin_thresh

public int[] meanMaxMin_thresh(int[] src,
                               int width,
                               int height,
                               int size,
                               int con)

Applies the adaptive thresholding operator to the specified image array using the mean of max & min function to find the threshold value

Parameters:

src - pixel array representing image to be thresholded

width - width of the image in pixels

height - height of the image in pixels

size - the size of the neigbourhood used in finding the threshold

con - the constant value subtracted from the mean

Returns:

a thresholded pixel array of the input image array
