JPEG2000, the new standard for still image coding, Quantization, user defined wavelets, arbitrary wavelet provides a new framework and an integrated toolbox to better decomposition...
In implementing an efficient block coder for JPEG2000, the memories required for storing the state variables dominate the hardware cost of a block coder. In this paper, we propose...
We present an efficient JPEG2000-based image authentication scheme, which is robust to JPEG compression and other allowed signal processing operations. Positive wavelet-based wate...
The Discrete Wavelet Transform (DWT) forms the core of the JPEG2000 image compression algorithm. Since the JPEG2000 compression application is heavily data-intensive, the overall ...
In this paper we present a new segmentation method for the Multidimensional Multiscale Parser (MMP) algorithm. In previous works we have shown that, for text and compound images, ...
