As the thresholds increased for both images the edges became more blurred. However, using

A 3x3 operator from a low threshold to a higher threshold did not vary as much as did the 7x7

Operator. The images also seem to exhibit a darker hue after applying the gaussian smoothing

Operation.

The median filter worked with eliminating the noise without sacrificing too much of the image

Quality with a 3x3 operator. With a 5x5 operator the noise completely vanished but the

Sharpness of the original image faded noticeably.

These runs were done on a 166MHz, 586 ibm compatible computer. As the window of the

Operator grew the time increased in a linear fashion, as expected. I tried to increase the performance

Of the gaussian operation by implementing the incremental method of a 1D by 1D window operator.

However, the inherent nature of the weights associated with the gauss' methology prevented its use.
