Gray level basedcorrelation method is a popular and classic algorithm in the image match registration, butthe computation is hard to meet the requirement of the real-time processing. A real-timeimplementation method of correlation algorithm on DSP TMS320C6201 is proposed, throughoptimizing the image data access format and the parallel of instructions, it costs fewertime for matching process but the same precision. Experiment shows that this method iseffective for matching computation on C6201.
