We investigate use of laser-accelerated electron beams for high resolution long standoff, radiographic applications and detection of shielded dense materials. For first time, radiographs with sub-millimeter resolution; embedded gaps in dense materials are presented.
Motivated by the optimization of power and improvement of video resolution, this paper proposes a content-based adaptive sampling system for video acquisition. Blind sampling suffers from the lack of resolution and blurring. However, use of a priori knowledge can provide intelligent sampling function that will reduce the blur artifacts. This paper proposes an information theoretic criteria-based sampling...
We address the problem of video super resolution - obtaining a single high-resolution video whose spatial and temporal resolutions are higher than any of the input low-resolution videos. We employ a reconstruction based approach using MRF -MAP formalism, and use approximate optimization using graph cuts to carry out the reconstruction. We show that in our formulation it is possible to selectively...
Susceptibility-weighted magnetic resonance imaging is a powerful tool for high resolution imaging of the vasculature, aiding in the diagnosis of many pathologic conditions. The technique is especially beneficial at higher field strengths where traditional sequences that measure cerebral blood volume suffer from severe distortions, rendering them inapplicable at 7 T. However, conventional susceptibility-weighted...
This paper presents a novel approach for speckle reduction of ultrasound image and its implementation using EDK 7.1i (Embedded Development Kit) on ML310 embedded development platform wherein the image is read from an image data file to a set of slave registers in the filter core through the On-Chip Peripheral Bus (OPB) and thereby processed in the filter core. Speckle is a phenomenon in ultrasonic...
In this age of multimedia convergence, video based applications for conferencing and streaming are seeing big market traction. The main challenge of implementing these systems is a tradeoff between several factors like bandwidth, image quality, implementation cost and speed (in terms of mega cycles per second). Moreover to implement this encoder-decoder system (CODECs) in a real time system based...
