retriveing some specific value from several matrix

Hi suppose I have some matrix of same size.I,I1,I2,I3. among them I as follows

I =

     1     1     1     1     8     1     2
     1     1     8     8     8     2     1
     1     8     8     1     2     1     1
     1     1     8     2     1     1     1
     2     2     2     1     1     1     1
     2     2     2     1     1     1     1

In I there are 3 distinct value 1,2 and 8.

I have declared a variable cell as follows:

InformationFromMatrix=cell(max(I(:))+1,1);

In each cell I need to store the following information:

There are seven 8.but seven of them are in boundary position with 1 and 2.

I need the following information in the 3rd cell:

8 1 1 5 1 4 column7 column8 column9

8 1 1 5 1 6 column7 column8 column9

8 1 3 2 2 2 column7 column8 column9

.....................................

8 2 3 3 4 4 column7 column8 column9

8 2 4 3 4 4 column7 column8 column9

.....................................

......................................

column1=8 ; 3rd distinct value

column2=1; one of 8's boundary value

column3= row index of the 8

column4= column index of the 8

column4= row index of the 1

column5= column index of the 1

column7 =absolute difference of I1 of position(1,5) and (1,4)

column8 =absolute difference of I2 of position(1,5) and (1,4)

column9 =absolute difference of I3 of position(1,5) and (1,4)

this so on will be for 1st and 2nd cell.

Is there any body to help me?

Thanks in advance.

What if an 8 (row 4, col 3) has two 2s and a 1 in the boundary (four connected compenents), which one to chose?
