Are there any inbuild function similar to bitrevorder in opencv?

edit

it isn't straightforward, but you could use a lookup table, generated like this:

for (unsigned n = 0; n<256; n++) {
    unsigned n2=0;
    for (int i=0; i<8; i++) {
        unsigned b = ((n >>(i)&1)>0);  
        n2 |= b<<(7-i);
    }
    cout << int((char)(n2))<< ",";
    if (n%16==15) cout << endl;
}

and use that later, in your java code:

byte [] rev = { // jikes, java's bytes are *signed*
    0,-128,64,-64,32,-96,96,-32,16,-112,80,-48,48,-80,112,-16,
