3x3-neighbor-pixel
Description
All the filters have needed neighbor data the current pixel in the image,here this function(res_window=cover_window(how many neighbor value for row ,how many neighbor value for column ,input image) produce the result( res_window(row,col,total size))
input
inp_img=2d data(row * col)
w=cover size
w=[3 3] = 3x3 cover pixel generation
output
o_img=result 3d
o_img(w(1),w(2),r*col)
if
inp_img=[1 2 3 4 5 6 ]
w=[3 3]
Soloution
it will construct new image
new_img=[0 0 0 0 0 0 1 2 3 0 0 4 5 6 0 0 0 0 0 0]
result
o_img(:,:,1)=[0 0 0 0 1 2 0 4 5]
o_img(:,:,2)=[0 0 0 1 2 3 4 5 6]
finally
o_img(1:3,1:3,6)
example
a=imread( pears.png )
b=rgb2gray(a)
c=cover_window( b,[3 3]) 3x3 window construction
