Lossy compression of permutations [PDF]
2014 IEEE International Symposium on Information Theory, 2014 We investigate the lossy compression of permutations by analyzing the trade-off between the size of a source code and the distortion with respect to Kendall tau distance, Spearman’s footrule, Chebyshev distance and `1 distance of inversion vectors.

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

Accuracy analysis of lossless and lossy disparity map compression
Ain Shams Engineering Journal, 2022 In this paper, we analysed lossless and lossy compression of disparity (depth) images with low range resolution. For that goal, the well-known publicly available Middlebury dataset is used with stereo image pairs, their disparity ground truths and ...

Topologically Controlled Lossy Compression [PDF]
2018 IEEE Pacific Visualization Symposium (PacificVis), 2018 This paper presents a new algorithm for the lossy compression of scalar data defined on 2D or 3D regular grids, with topological control. Certain techniques allow users to control the pointwise error induced by the compression. However, in many scenarios it is desirable to control in a similar way the preservation of higher-level notions, such as ...

The Likelihood Encoder for Lossy Compression [PDF]
IEEE Transactions on Information Theory, 2016 A likelihood encoder is studied in the context of lossy source compression. The analysis of the likelihood encoder is based on the soft-covering lemma. It is demonstrated that the use of a likelihood encoder together with the soft-covering lemma yields simple achievability proofs for classical source coding problems.
