Improvements on stochastic vector quantization of images [PDF]
, 1993 A novel nonadaptive fixed-rate vector quantizer encoding scheme is presented, and preliminary results are shown. The design of the codebook has been based on a stochastic approach in order to match a previously defined model for the image to be encoded ...

STUDI BANDING ALGORITMA KOMPRESI HUFFMAN CODING DAN ADAPTIVE HUFFMAN CODING [PDF]
, 2017 ABSTRAK Algoritma kompresi menurut David Solomon (2007:2) adalah proses mengkonversikan sebuah input data stream (streamsumber, atau data mentah asli) menjadi data stream lainnya (bitstream hasil, atau stream yang telah terkompresi) yang ...

First-Come-First-Served for Online Slot Allocation and Huffman Coding [PDF]
, 2013 Can one choose a good Huffman code on the fly, without knowing the underlying distribution? Online Slot Allocation (OSA) models this and similar problems: There are n slots, each with a known cost. There are n items.

Pemampatan Citra Keabuan dengan Algoritma Adaptive Huffman dan LZW
Jurnal Teknik ITS, 2016 Perkembangan data digital cukuplah pesat, mulai dari ukuran hingga jenis berkas. Untuk mengimbangi hal tersebut maka perlu ada-nya algoritma pemampatan guna mengurangi ukuran penggunaan media penyimpanan. Salah satu algoritma yang cukup lama ada adalah Adaptive Huffman, dan serta mengkombinasikannya dengan LZW, maka hasil pemampatan yang didapat akan ...

Anomaly Detection in Audio with Concept Drift using Adaptive Huffman Coding
, 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.

Hybrid threshold adaptable quantum secret sharing scheme with reverse Huffman-Fibonacci-tree coding [PDF]
Scientific Reports, 2016 AbstractWith prevalent attacks in communication, sharing a secret between communicating parties is an ongoing challenge. Moreover, it is important to integrate quantum solutions with classical secret sharing schemes with low computational cost for the real world use.
