Initial Target Region Estimation Suitable to Optical Tacking
Due to be sensitive to noise for unsymmetry target
General center of mass can not locate well for optical tracking
and the macro divided method has good anti-noise capacity
but it is too computationally intensive. The macro-pixels method was used to reduce calculation time. For the unsymmetry target of 4×4 pixels in 128×128 pixel spot picture
the value of r could be optimal as 36 pixel of Micro pixel dimensions and target macro-pixels enlarged to 2 pixel according to less calculation time and better in anti-noise capacity. The value of r is 1 when SNR is 5 dB. Dynamic picture test shows that the improved arithmetic has 18~20 frame/s of processing speed.
