Study on Ownership Identification Using Discrete Wavelet Transform (DWT)-Based LOGO Watermarking

2021
An efficient DWT-based watermarking technique is proposed in this research to insert gray-scale logos as a watermark in images to attest the owner identify and discourage unauthorised copying. To hide a higher energy hidden watermark in conspicuous picture components, the method converts both the host image and the watermark into the discrete wavelet ...

Data fusion of multiple polarimetric SAR images using discrete wavelet transform (DWT)

IEEE International Geoscience and Remote Sensing Symposium, 2003
Data fusion is a very effective technique which can be applied to many remote sensing areas such as classification, monitoring of environmental surveillance and man-made target tracking. In this paper, we tested fusion of multiple frequency (C-, and L-band), multiple polarization (HH, HV and VV) and multiresolution data sets.
