image processing using LPF, grading and edging

Hi,

Requesting kind reply for this post. i have already posted one question and dint receive any help. But please help me for this atleast. I need to know

to create an image pyramid with 3 levels. Assume the zero level of the pyramid, G0, is
equal to the original image. Apply lowpass filtering to G0 using the following LP filter

h=
[0 1/8 0
1/8 1/2 1/8
0 1/8 0]

and subsample by a factor of two to obtain the next pyramid level G1. Repeat the
step of filter and subsample on G1 to obtain the second level G2. Display G0, G1 and
G2.
(3) Compute image gradients using Sobel operators and display the gradient magnitude
images of G0 , G1 and G2.
(4) Detect edges in G0 , G1 and G2 by thresholding the gradient magnitude images. A
good threshold value should be decided empirically. Display the edge images.


Expecting your kind reply and help.

Because in both posts you are asking someone to do your homework/assignment for you. Both posts look like you cut and pasted the text of the assignment into an edaboard new post window.
