AN ALGORITHM OF ADAPTIVE LIFTING WAVELET TRANSFORM COMPUTATION based on prediction error diffusion
Доклады Белорусского государственного университета информатики и радиоэлектроники, 2019 An algorithm of adaptive lifting wavelet transform computation based on adaptive prediction of the detail wavelet coefficients, with using subbands halftone image obtained from the original grayscale is proposed. The results of an algorithm modeling show

Lossless compression of image data products on th e FIFE CD-ROM series [PDF]
How do you store enough of the key data sets, from a total of 120 gigabytes of data collected for a scientific experiment, on a collection of CD-ROM's, small enough to distribute to a broad scientific community?

Using 3DF Zephyr to determine body‐worn camera position
Journal of Forensic Sciences, EarlyView.Abstract Photogrammetry has been used consistently in forensic settings to document crime scenes three‐dimensionally. Traditionally, a large number of still photos are taken, and information from those photos is used to create a three‐dimensional (3D) model.

High-Speed Architecture for Hybrid Arithmetic–Huffman Data Compression
TechnologiesThis paper proposes a hardware–software co-design for adaptive lossless compression based on Hybrid Arithmetic–Huffman Coding, a table-driven approximation of arithmetic coding that preserves near-optimal compression efficiency while eliminating the ...

Information and affective valence influence judgments of complexity, liking and understanding
British Journal of Psychology, EarlyView.Abstract Visual complexity is a key factor in perceptual and evaluative judgments. People's representation of visual complexity is constructed from quantitative and structural image features, but it is also influenced by familiarity and expertise. We examined how people represent visual complexity and its impact on perception and evaluation, focusing ...

Splatshop: Efficiently Editing Large Gaussian Splat Models
Computer Graphics Forum, EarlyView.Abstract We present Splatshop, a highly optimized toolbox for interactive editing (selection, deletion, painting, transformation, …) of 3D Gaussian Splatting models. Utilizing a comprehensive collection of heuristic approaches, we carefully balance between exact and fast rendering to enable precise editing without sacrificing real‐time performance. Our

Image‐Based Spatio‐Temporal Interpolation for Split Rendering
Computer Graphics Forum, EarlyView.Abstract Low‐powered devices – such as small form factor head‐mounted displays (HMDs) – struggle to deliver a smooth and high‐quality viewing experience, due to their limited power and rendering capabilities. Cloud rendering attempts to solve the quality issue, but leads to prohibitive latency and bandwidth requirements, hindering use with HMDs over ...

Encoding Occupancy in Memory Location for Efficient and Compact High‐Resolution Voxel Structures
Computer Graphics Forum, EarlyView.We encode information about geometric structure into the pointers of a sparse voxel directed acyclic graph (SVDAG). Each pointer carries information about the structure of the node it points to. Our encoding improves ray tracing performance and reduces model size in memory.

Locally adaptive vector quantization: Data compression with feature preservation [PDF]
A study of a locally adaptive vector quantization (LAVQ) algorithm for data compression is presented. This algorithm provides high-speed one-pass compression and is fully adaptable to any data source and does not require a priori knowledge of the source ...
