A Block-Based Inter-Band Lossless Hyperspectral Image Compressor
Abstract: We propose a hyperspectral image compressor called BH which considers its input image as being partitioned into square blocks, each lying entirely within a particular ban...

Lossy Compression of Bilevel Images Based on Markov Random Fields
A new method for lossy compression of bilevel images based on Markov random fields (MRFs) is proposed. It preserves key structural information about the image, and then reconstru...

Adaptive Wavelet-based-CMAC Network Predictor Design for Lossless Image Coding
— In this paper, we propose a novel wavelet-based-CMAC (WCMAC) network for predictive image coding. The Gaussian functions of traditional CMAC are replaced by wavelet functions. ...

Efficient Compression of Encrypted Grayscale Images
—Lossless compression of encrypted sources can be achieved through Slepian-Wolf coding. For encrypted real-world sources such as images, the key to improve the compression effici...
