Robot Vision : Internal and External Corner detection code

Dear All,

I am newbee to MATLAB, please experts suggest me THe code for internal and external code detection the basic algoristh is here

procedure count_objects(B);
{
    E:=0;
    I:=0;
    for L:= 0 to MaxRow - 1
    for P:= 0 to MaxRow - 1
        {
            if external_match(L,P) then E:=E+1;
                if internal_match(L,P) then I:=I+1;
                    };
                    return((E-1)/4);
                }
