Effect of lossy data compression techniques on geometry and information content of satellite imagery
Data compression Satellite imagery JPEG Wavelets
2016/5/23
The recording and transfer rates of digital imaging systems can not keep abreast of the actual captured amount of data.Because the compression rates of standard loss-less techniques are still too low,...

Coincidence,data compression,and Mach’s concept of “economy of thought”
Coincidence data compression Mach’s concept economy of thought
2015/7/30
A case is made that Mach’s principle of “economy of thought”, and therefore usefulness, is related to the compressibility of data, but that a mathematical expression may compress data for reasons that...
VECTOR GEOSPATIAL DATA COMPRESSION FOR WEBGIS AND CARTOGRAPHIC GENERALIZATION
WebGIS vector geospatial data data compression cartography generalization
2015/3/6
This paper introduces the author's work on the compression of vector geospatial data intended for transport on the Internet. WebGIS vector data format is shifting to ASCII code such as XML. In some ap...
THE IMPACT OF DATA COMPRESSION AND NEIGHBORHOOD INFORMATION ON THE CLASSIFICATION ACCURACY OF ARTIFICIAL NEURAL NETWORKS
Neural Networks Thematic Classification Principal Component Analysis
2015/2/3
The artificial neural networks are nice tools in the thematic mapping. The classification procedure requires carefully prepared training set. The research was aimed to show the effect of the generally...
High-throughput, lossless data compression and decompression on FPGAs
Data is written to a storage medium transmission the system performance
2014/12/31
Before writing data to a storage medium or transmitting across a transmission medium lossless compression is often used. Storage space or transmission bandwidth is saved by compression; when the data ...
Enhanced Search And Efficient Storage Using Data Compression In Nand Flash Memories
Nand Flash Search data deduplication MISR
2014/12/8
NAND flash memories are popular due to their density and lower cost. However, due to serial access, NAND flash memories have low read and write speeds. As the flash sizes increase to 64GB and beyond, ...
