Windowed Huffman coding algorithm with size adaptation [PDF]
IEE Proceedings I Communications, Speech and Vision, 1993 The windowed Huffman algorithm is introduced. The Huffman code tree is constructed based on the probabilities of symbols' occurrences within finite history in this windowed algorithm. A window buffer is used to store the most recently processed symbols.

Anomaly Detection in Audio with Concept Drift using Adaptive Huffman Coding
CoRR, 2021 When detecting anomalies in audio, it can often be necessary to consider concept drift: the distribution of the data may drift over time because of dynamically changing environments, and anomalies may become normal as time elapses. We propose to use adaptive Huffman coding for anomaly detection in audio with concept drift.

Adaptive Polynomial Fitting for Image Compression Based on Variance of Block Pixels [PDF]
Engineering and Technology Journal, 2015 This paper presents a proposed method to compress images using two polynomials with different models based on the value of block pixels variance. These two polynomials are chosen from different set of models, which give low number of coefficients and ...

Entropy Coding Aided Adaptive Subcarrier-Index Modulated OFDM
IEEE Access, 2018 We propose entropy coding-aided adaptive subcarrier-index-modulated orthogonal frequency division multiplexing (SIM-OFDM). In conventional SIM-OFDM, the indices of the subcarriers activated are capable of conveying extra information. We propose the novel
