+# DePepper
+
+Remove Salt and Pepper noise.
+
+Test images can be found at http://www.fit.vutbr.cz/~vasicek/imagedb/23
+
+Note: of course, if would be better to use the median of neighbor values rather than the average to replace the color.
+
+If the noise covers several neighboring pixels, apply it two times.
