A NEW APPROACH OF EDGE DETECTION IN SAR IMAGES USING REGION-BASED ACTIVE CONTOURS
Kotagiri Ramadevi · 2013
This paper presents a new methodology for the edge detection of complex radar images. The approach inc ludes the edge improvisation algorithm and followed with edge dete ction. The nature of complex radar images made edge enhancement part before the edge detection as the data is highly het erogeneous in nature. Thus, the use of discrete wav elet transform in the edge improvisation algorithm is justified. Then region b ased active contour model is used as edge detection algorithm. The paper proposes the distribution fitting energy with a lev el set function and neighborhood means and variance s as variables. The performance is tested by applying it on different iand the results are been analyzed.
