چکیده

A secured compressed sensing (CS) systems design approach uses a novel deterministic matrix to sense and transmit fingerprint images. The performance of the CS system was studied in detail by varying security parameters. sampling sparse coefficient are parameters considered from sensing, whereas encryption key is scheme. simultaneous compression has been achieved multiplying modeled data with proposed partial bounded orthogonal matrix. chaotic model-based permutation applied scramble DCT rows build Recovering decryption image accomplished help L1 optimization method. experimental test shows that vector 121 widths recovered taking about 25 samples. This indicates up 1 : 5 ratio supported without damaging minutiae. If only required encryption, 16 can be achieved. peak signal-to-noise (PSNR) 27.65 dB for both ratios under fulfilments all necessary requirements. 7.20 value entropy, histogram analysis, correlation analysis show scheme possesses adequate randomness. Furthermore, ability resistance against attacks proved 100% NPCR (Net Pixel Change Rate) 0.92% UACI (Unified Average Changing Intensity) values.

The Chaotic Measurement Matrix for Compressed Sensing

How to construct a measurement matrix with good performance and easy hardware implementation is the core research problem in compressed sensing. In this paper, we present a simple and efficient measurement matrix named Incoherence Rotated Chaotic (IRC) matrix. We take advantage of the well pseudorandom of chaotic sequence, introduce the concept of the incoherence factor and rotation, and adopt ...

A single-pixel terahertz imaging system based on compressed sensing

We describe a terahertz imaging system that uses a single pixel detector in combination with a series of random masks to enable high-speed image acquisition. The image formation is based on the theory of compressed sensing, which permits the reconstruction of a N-by-N pixel image using much fewer than N2 measurements. This approach eliminates the need for raster scanning of the object or the te...

Toward deterministic compressed sensing.

Over the past decade, compressed sensing has delivered significant advances in the theory and application of measuring and compressing data. Consider capturing a 10 mega pixel image with a digital camera. Emailing an image of this size requires an unnecessary amount of storage space and bandwidth. Instead, users employ a standard digital compression scheme, such as JPEG, to represent the image ...

Compressed Sensing based Diffusion Spectrum Imaging

Introduction: Several methods are currently used to resolve multiple fibers within a voxel including Q-space imaging such as DSI and QBI. These approaches are generally limited by the burden of dense sampling in Q-space to avoid aliasing, which makes their application to clinical studies difficult. However, compressed sensing (CS) can attain almost perfect reconstruction from incomplete random ...

Compressed Sensing Based Fingerprint Identification for Wireless Transmitters

Most of the existing fingerprint identification techniques are unable to distinguish different wireless transmitters, whose emitted signals are highly attenuated, long-distance propagating, and of strong similarity to their transient waveforms. Therefore, this paper proposes a new method to identify different wireless transmitters based on compressed sensing. A data acquisition system is design...
