چکیده
Absirac--This paper proposes a new nonlinear multiseale monslrmction method for image enhancement using dual-tree complex wavelet hansfona The enhanced image is obtained by succ&vely combining each coarser d e image with the corresponding nonlinearly modified iniersesle (detail) images. This image enhancement method reduces additive noise wbile presema the sharpnesc of the image. Simulation resnlts show the improved performance of our image enhancement method in comparison with that of the existing methods.

The Dual-Tree Complex Wavelet Transform – A Coherent Framework for Multiscale Signal and Image Processing
The dual-tree complex wavelet transform (CWT) is a relatively recent enhancement of the discrete wavelet transform (DWT) with important additional properties: It is nearly shift-invariant and directionally selective in two and higher dimensions. It achieves this with a redundancy factor of only 2 for d-dimensional signals, which is substantially lower than the undecimated DWT. The multidimensio...

متن کاملRobust Satellite Image Resolution Enhancement using Double Density Dual Tree Complex Wavelet Transform
Image Resolution enhancement (RE) schemes which are based on wavelets have an advantage over conventional methods which suffer from the losing of high frequency contents which causes blurring. The discrete wavelet transform-based (DWT) RE scheme generates artifacts due to a DWT shift-variant property. A wavelet-domain approach based on double density dual-tree complex wavelet transform (DDDT-CW...
متن کاملImage De-noising Using Dual-tree Complex Wavelet Transform for Satellite Applications
This paper presents a unique thanks to cut back noise introduced or exacerbated by image sweetening strategies; especially algorithms supported the random spray sampling technique, however not solely. Multi scale decomposition based on dual-tree complex wavelet transform and edge preservation is presented for SRE of the satellite images. Resolution enhancement schemes (which are not based on wa...
