extends Object
implements Modulable
Perform a convolution of filter on a Grey picture. The convolution algorith works as follows: for pixels in the picture a new value is calculated by weighing the values of its neighbours. If you for example take a 3x3 mask that contains all 1's we will put it 'over' the pixel we are calculating the new value of. (The middle value of the mask is over the pixel). Multiply all 9 pixels by the value of the mask that is 'over' the pixel, now add these values together and devide that number by the sum of the values in the mask. The resulting value is the new value for the pixel. Repeat this for all pixels in the picture.

Depending on the mask of the filters filters can be used in two ways: to reduce noise in a picture or to sharpen edges (note: this increases noise).
