A study of correlation technique on pyramid processed images

The pyramid algorithm is potentially a powerful tool for advanced televisio n image processing and for pattern recognition. An attempt is made to desig n and develop both hardware and software for a system which performs decomp osition and reconstruction of digitized images by implementing the Burt pyr amid algorithm. In this work, an attempt is also made to study correlation performance on r econstructed images. That is, the reference image is taken from the origina l image and correlation is performed on expanded images of the same size. S imilarly, correlation performance study is carried out on different pyramid -processed levels. In this paper results are presented in terms of RMS erro r between original and expanded images. Only still images are considered, a nd the hardware is designed around an i486 processor and software is develo ped in PL/M 86.
