Low pass filter

Now it is high time for us to speak about filters.Before we do this first we have to understand what is frequency in an image. To understand the existence of frequency in an image we would have to look at a diagram below.

Computing Power of an Image.

Now after cubing the image let us see how to compute any power on the image.Since we have already have computed the cube of the image now let us try our hands on square rooting the image.

Computing Cube of an Image

Let us see what changes happen when we cube the image. There are some special charecteristics which the numbers exhibit in the range of 0-1.When we apply some transformations let us see what affects they have on the image.
