Efficient and low-complexity image coding with the lifting scheme and modified SPIHT
—In this paper, we propose an efficient and low complexity image coding algorithm based on the lifting wavelet transform and listless modified SPIHT (LWT-LMSPIHT). LWT-LMSPIHT jo...

RST-Invariant Semi-fragile Image Authentication Based on DWT-Coefficient Quantization
Abstract. In this paper, we propose an image moment-based geometric normalization to be applied before embedding and extracting a digital watermark in the DWT-domain of JPEG2000. A...

Face recognition using anisotropic dual-tree complex wavelet packets
In this paper, we propose a novel face recognition method based on anisotropic dual-tree complex wavelet packets(ADT-CWP). 2-D dual-tree complex wavelet transform(DT-CWT) provides...
