Single-pixel imaging via compressive sampling

by Marco F. Duarte, Mark A. Davenport, Dharmpal Takhar, Jason N. Laska, Ting Sun, Kevin F. Kelly, Richard G. Baraniuk - IEEE Signal Processing Magazine
"... Humans are visual animals, and imaging sensors that extend our reach – cameras – have improved dramatically in recent times thanks to the introduction of CCD and CMOS digital technology. Consumer digital cameras in the mega-pixel range are now ubiquitous thanks to the happy coincidence that the semi ..."

fuses a new camera architecture based on a digital mi-cromirror device (DMD – see Sidebar: Spatial Light Modulators) with the new mathematical theory and algorithms of compressive sampling (CS – see Sidebar: Compressive Sampling in a Nutshell). CS combines sampling and compression into a single

An architecture for compressive imaging

by Michael B. Wakin, Jason N. Laska, Marco F. Duarte, Dror Baron, Shriram Sarvotham, Dharmpal Takhar, Kevin F. Kelly, Richard G. Baraniuk - in IEEE International Conference on Image Processing (ICIP , 2006
"... Compressive Sensing is an emerging field based on the revelation that a small group of non-adaptive linear projections of a compressible signal contains enough information for reconstruction and processing. In this paper, we propose algorithms and hardware to support a new theory of Compressive Imag ..."

Compression

by M. Puttaraju, Dr. A. R. Aswatha
"... Abstract — The wavelet transform has emerged as a cutting edge technology, in the field of image compression. Wavelet-based coding provides substantial improvements in picture quality at higher compression ratios. In this paper an approach is proposed for the compression of an image using 5/3(lossle ..."

System-on-a-Chip Test-Data Compression and Decompression Architectures Based on Golomb Codes

by Anshuman Chandra, Student Member, Krishnendu Chakrabarty, Senior Member , 2001
"... We present a new test-data compression method and decompression architecture based on variable-to-variable-length Golomb codes. The proposed method is especially suitable for encoding precomputed test sets for embedded cores in a system-on-a-chip (SoC). The major advantages of Golomb coding of test ..."

"... Spiral Architecture is a new and powerful approach to a general-purpose machine vision system. Earlier research compression on the Spiral Architecture focused on the properties of the pixel address labeling scheme. This gives rise to the property of interest which is the physical proximity of the he ..."

Code Compression for Low Power Embedded System Design

by Haris Lekatsas, Jörg Henkel, Wayne Wolf , 2000
"... We propose instruction code compression as a very efficient method for reducing power on an embedded system. Our approach is the first one to measure and optimize the power consumption of a complete SOC (System--On--a--Chip) comprising a CPU, instruction cache, data cache, main memory, data buses an ..."
