In this paper we propose a new wavelet transform applicable to functions defined on graphs, high dimensional data and networks. The proposed method generalizes the Haar-like transf...
—The JPEG 2000 image coding standard employs the biorthogonal 9/7 wavelet for lossy compression. The performance of hardware implementation of 9/7-filter bank depends on accuracy...
— Motivated by video coding applications, we study the problem of sequential coding of correlated sources with (noncausal) encoding and/or decoding frame-delays. The fundamental ...
Selective encryption is a new trend in content protection. It aims at reducing the amount of data to encrypt while achieving a sufficient and inexpensive security. This approach ...
—JPEG2000 image compression standard is designed to cater the needs of a large span of applications including numerous consumer products. However, its use is still restricted due...
