I need to get the circled values into 4 arrays(considering the four directions). note : I obtained the pixel values in image which is attached herewith, by multiplying the mask value and original image pixels. Could you please help me.

Your question is not very clear. If I am interpreting your question correctly,

Awest = A(3:8,4); 
Anorth = A(3,5:8); 
Aeast = A(4:7,8); 
Asouth = A(8,5:8);

I was going to say the same thing. Given what he's told us, this is a perfectly reasonable answer. If not, he needs to say why not and what is needed to make it more general or whatever.

Hi,Chad and Image Analyst, sorry for the lack of details given for my question. Actually the circled pixel values are the boundary value of a damaged area of an digital image. Really what I want is, to get the pixel values of four directions(north, east, west and north) separately in to the four arrays. Actually the attached image just for an example. I really appreciate your response and I did not understand the values obtained to the answer above. Think that u can understand my problem now.
