Lossless Image Compression by Joint Prediction of Pixel and Context Using Duplex Neural Networks

IEEE Access, 2021
This paper presents a new lossless image compression method based on the learning of pixel values and contexts through multilayer perceptrons (MLPs). The prediction errors and contexts obtained by MLPs are forwarded to adaptive arithmetic encoders, like ...

LOCO-ANS: An Optimization of JPEG-LS Using an Efficient and Low-Complexity Coder Based on ANS

IEEE Access, 2021
Near-lossless compression is a generalization of lossless compression, where the codec user is able to set the maximum absolute difference (the error tolerance) between the values of an original pixel and the decoded one.

Dynamic Neural Network for Lossy-to-Lossless Image Coding

IEEE Transactions on Image Processing, 2021
Lifting-based wavelet transform has been extensively used for efficient compression of various types of visual data. Generally, the performance of such coding schemes strongly depends on the lifting operators used, namely the prediction and update ...

An Efficient Lossless Compression Method for Periodic Signals Based on Adaptive Dictionary Predictive Coding

Applied Sciences, 2020
This paper reports on an efficient lossless compression method for periodic signals based on adaptive dictionary predictive coding. Some previous methods for data compression, such as difference pulse coding (DPCM), discrete cosine transform (DCT ...

Universal lossless source coding with the Burrows Wheeler transform [PDF]

, 2002
The Burrows Wheeler transform (1994) is a reversible sequence transformation used in a variety of practical lossless source-coding algorithms. In each, the BWT is followed by a lossless source code that attempts to exploit the natural ordering of the BWT

A new efficient predictor blending lossless image coder [PDF]

International Journal of Electronics and Telecommunications
In the paper a highly efficient algorithm for lossless image coding is described. The algorithm is a predictor blending one, a sample estimate is computed as a weighted sum of estimates given by subpredictors, here 27 ones, hence the name Blend-27.
