l bnl compress: Lossy but not lossy compression, a python script to compress MX data [PDF]

Structural Dynamics
l_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 ...

Unlocking the potential of digital pathology: Novel baselines for compression [PDF]

Journal of Pathology Informatics
Digital pathology offers a groundbreaking opportunity to transform clinical practice in histopathological image analysis, yet faces a significant hurdle: the substantial file sizes of pathological whole slide images (WSIs).

Evaluation and analysis of image compression effect on neural network-based heart rate classification [PDF]

Scientific Reports
In this study, we evaluated and analyzed the effects of image compression on a neural network (NN)-based heart rate (HR) classification system. An NN-based HR-estimation system classifies facial images into groups of HR intervals.

Adaptive Vector Quantization for Lossy Compression of Image Sequences

Algorithms, 2017
In this work, we present a scheme for the lossy compression of image sequences, based on the Adaptive Vector Quantization (AVQ) algorithm. The AVQ algorithm is a lossy compression algorithm for grayscale images, which processes the input data in a single-

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 ...
