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

                               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
