In this paper, we study the nonsubsampled higher-density discrete wavelet transform (NS-HDDWT) and its application in image enhancement. In contrast to the HDDWT, the NS-HDDWT transform is shift-invariant, which is a desirable feature in many applications. We address the filter design problem...

English: The program is written based on MATLAB R2018b and features a GUI interface (developed in the GUIDE environment). It utilizes wavelet transform for image processing, which includes image fusion, denoising, compression, and image hiding. The program provides sample image materials for testing...
In this lecture, the process of wavelet transform (WT) is reported for the image patterns of photomechanics, that involve carrier fringe patterns and randomly distributed speckle patterns. For the frequency modulated carrier patterns, the results from wavelet transform are compared with that from Four...
