Efficient way to filter out a matrix?

    Hi everyone,
    I am trying to figure out a way to filter out repetitions inside a matrix more efficiently. I have to scale 10 times what I am doing and it slows down the CPU.
    In the example below you have something similar to what I am trying to achieve. Minus the fact that the input will come from jit.openni while using a kinect. Practically I want to know when somebody is leaving the scene.
    The patch in the example works without a kinect to demonstrate the problem.
    PS: Can [jit.op @op == @val 1] be substituted for..
    jit.gl.gen Param thresh(1); eq_1 = in1 == thresh; out1 = eq_1;
    ? (see also example in the patch)
    Thank you for any input!!
