The Micro-Pits Image Design Method with Direction-Uniformity Distribution Based on Minimum Interval Area Scrambling

It is bigger that SRadcv of the micro-pits image based on square area scrambling, and the uniformity of micro-pits distribution is not very good. An improved method is presented that presetting the minimum interval of the micro-pits, and setting positions of these micro-pits randomly, then optimizing the positions of the micro-pits by area scrambling. SRadcv of the micro-pits image generated in this method will be much smaller, and the uniformity of the micro-pits distribution will be very good.
