Lossless Volume Data Compression Schemes

Volumetric data is one of the most frequently generated type of data in modern medical imaging. Technical advances in the respective scanning technologies also increase the amount of data that is generated by a typical scanner. Since 1971 with the introduction of the first CT scanner, the space requirements for representing data have increased rapidly, in essence at an exponential rate. In this...

Adaptive Geometry Compression Based on 4-Point Interpolatory Subdivision Schemes

We propose an adaptive geometry compression method based on 4-point interpolatory subdivision schemes. It can work on digital curves of arbitrary dimensions. With the geometry compression method, a digital curve is adaptively compressed into several segments with different compression levels. Each segment is a 4-point subdivision curve with a subdivision step. In the meantime, we provide high-s...

Adaptive Online Data Compression

Quickly transmitting large datasets in the context of distributed computing on wide area networks can be achieved by compressing data before transmission. However, such an approach is not efficient when dealing with higher speed networks. Indeed, the time to compress a large file and to send it is greater than the time to send the uncompressed file. In this paper, we explore and enhance an algo...

Adaptive surface data compression

Three-dimensional visualization techniques are becoming an important tool for medical applications. Computer generated 3D reconstructions of the human skull are used to build stereolithographic models, which can be used to simulate surgery or to create individual implants. Anatomy-based three-dimensional models are used to simulate the physical behaviour of human organs. These 3D models are usu...

adaptive non‑uniform rate sampling and application in data compression

in this paper the author considers a general method, based on time domain samples for spectral manipulation of time limited signals. first, the original signal is divided into some frames in the time domain. then, by presenting a suitable theoretical and computational algorithm, and using a method for improving the speed of convergence, we find the local bandwidth of each frame; thereby, each f...
