Belief Propagation Optimization for Lossy Compression Based on Gaussian Source [PDF]
Sensors, 2023 In the Internet of Things, sensor nodes collect environmental information and utilize lossy compression for saving storage space. To achieve this objective, high-efficiency compression of the continuous source should be studied.

Universality of Logarithmic Loss in Fixed-Length Lossy Compression [PDF]
Entropy, 2019 We established a universality of logarithmic loss over a finite alphabet as a distortion criterion in fixed-length lossy compression. For any fixed-length lossy-compression problem under an arbitrary distortion criterion, we show that there is an ...

l bnl compress: Lossy but not lossy compression, a python script to compress MX data [PDF]
Structural Dynamicsl_bnl_compress.py is a python script implementing the lossy compressions described in [1] for macromolecular crystallographic diffraction data. The lossy compressions use pixel-by-pixel binning, image-by-image summing, JPEG-2000 Daubechies (DB) wavelet ...

Toward Extreme Lossy Compression Data to Enable Higher Data Rates MX [PDF]
Structural DynamicsAt last, a useful lossy compression method is available for MX crystallographic data. One could achieve a compression ratio as high as 3000 to 1, but with data loss so high that structural data can’t be interpreted faithfully.

The Cosmos and Crystal Connection: What We Can Learn About Data Compression [PDF]
Structural DynamicsWe use both lossy and lossless compression methods to reduce large amounts of digital data, making it easier to store and manage. Lossy and lossless compression is frequently used in astronomy, to condense the large amount of data collected by ...

Lossy P-LDPC Codes for Compressing General Sources Using Neural Networks
Entropy, 2023 It is challenging to design an efficient lossy compression scheme for complicated sources based on block codes, especially to approach the theoretical distortion-rate limit. In this paper, a lossy compression scheme is proposed for Gaussian and Laplacian
