algorithms for digital image correlation often used at present
are intruduced and discussed in principle and simulated by IBM pC/AT microcomputer. A mixed algorithm is proposed
based on product correlation and sum of absolute differenes algorithms. It shows that the performance of nomalized product correlation can be improved with the subtraction of the grey scale value of average from that of every pix in an image.To examine noise immunity of algorithms
pseudorandom noise mean of which is zero is added to the test image' Some considerations the for implementing these algorithms are presented.
