Max Filter
The Maximum filter enhances bright values in the image by
increasing its area. Similar to a dilate function each 3x3 (or other window
size) is processed for the brightest surrounding pixel. That brightest pixel
then becomes the new pixel value at the center of the window.
For example, given the grayscale 3x3 pixel neighborhood;
|
22 |
77
|
48
|
|
150
|
77
|
158
|
|
0
|
77
|
219
|
The center pixel would be changed from 77 to 219 as it is
the brightest pixel within the current window.
