In recent years,multi-scale geometric analysis(MGA) has been widely used for research and applications in statistical analysis,pattern recognition,signal processing and digital image processing,etc.As an adaptive MGA method,Bandelet transform can track geometrical regularity of image structure adaptively and represent sharp image transition.Being able to provide the sparsest representation,Bandelet could use less nonzero coefficients to reach the same identification effect as other basic functions,especially more superior in image with significant geometric features.Introduced the development and principles of Bandelet transform in detail,and further researched the application in image smoothing,compression,segmentation and fusion.Finally trend in development were also pointed out.
