Automatic Channel Fault Detection on a Small Animal APD-Based Digital PET Scanner
Avalanche photodiode (APD) based positron emission tomography (PET) scanners show enhancedimaging capabilities in terms of spatial resolution and contrast due to the one to one coupling and size of individual crystal-APD…
High capacity and robust speech data hiding in colour images
Steganography is a method for hiding information in a host signal. The host signal can be a still image, speech or video and the message signal that is hidden in the…
Ground-based mobile passive imagery based on a DVB-T signal of opportunity
A new approach to passive bistatic radar imaging using DVB-T signals as illuminators of opportunity is presented. The concept has been verified using ground based mobile platforms as a radar receiver carrier.…
Segmentation of plate dot image based on image processing techniques
The accurate of printing plate dot size makes a significant impact on the reproduction of image gradient and color in the halftone image replication. Therefore, in order to eliminate the effect of noise, first…
A combined object-based segmentation and support vector machines approach for classification of Tiangong-01 hyperspectral urban data
Traditional hyperspectral classification methods based on per-pixel spectral or texture features fail to take account of spatial structure and spatial correlation characteristics. In order to overcome this problem, a mixed…
Towards a Linked Data Vocabulary for the Certification of Software Properties
In order to cater for a growing user base that requires varied functionalities and owns multiple devices, software providers are using cloud solutions as the preferred technical means. In fact,…
High-speed compressed sensing measurement using spectrally-encoded ultrafast laser pulses
We present a chirp processing technique for encoding pseudorandom patterns onto the spectra of broadband optical pulses for compressed sensing (CS) measurement. We demonstrate applications to characterization of ultrawideband sparse radio frequency…
Self Embedding Fragile Watermarking for Image Tampering Detection and Image Recovery Using Self Recovery Blocks
Fragile watermarking is discovered for authentication and content integrity verification. This paper introduces a modified fragile watermarking technique for image recovery. Here we can detect as well as recovered the tampered image with its…
A Continuous-Time Delta-Sigma Modulator for Biomedical Ultrasound Beamformer Using Digital ELD Compensation and FIR Feedback
This paper presents the design of a continuous-time ΔΣ modulator (CTDSM) to be used in an ultrasound beamformer for biomedical imaging. To achieve better resolution, the prototype modulator operates at 1.2…
