Key Technoligies of Compress Algorithm with Edge Featuring Wavelet Transform

This paper describes and discusses egde perserving wavelet transform and edge coding.They are two key technologies for new progressive compress algorithm that focus on preserving the clarity of important image features,such as edges.With two technologies capture and encode the location of important edges in the images,new progressive algorithm preserving important edge feature that may be important for recognition and quick browse,even at low bit rates.At the same time,the paper gives experiment result at Matlab6.5 and analyses the result.
