Encrypting video and image streams using OpenCL code on-demand
The amount of multimedia information transmitted through the web is very high and increasing. Generally, this kind of data is not correctly protected, since users do not appreciate the amount of information that images and videos may contain. In this work, we present architecture for managing safely multimedia transmission channels. The idea is to encrypt or encode images and videos in an effic...
متن کاملOpenCL-accelerated object classification in video streams using Spatial Pooler of Hierarchical Temporal Memory
The paper presents a method to classify objects in video streams using a brain-inspired Hierarchical Temporal Memory (HTM) algorithm. Object classification is a challenging task where humans still significantly outperform machine learning algorithms due to their unique capabilities. A system which achieves very promising performance in terms of recognition accuracy have been implemented. Unfort...
متن کاملEnhanced Delivery of Video-on-Demand Streams to Heterogeneous Receivers*
The required real-time and high-rate transfers for multimedia data severely limit the number of requests that can be serviced concurrently by Video-on-Demand (VOD) servers. Resource sharing techniques can be used to address this problem. We study how VOD servers can support heterogeneous receivers while delivering data in a client-pull fashion using enhanced resource sharing. We propose three h...
متن کاملScheduling Video Streams in a Large-Scale Video-On-Demand Server
This paper addresses the design problems concerning a large scale parallel video on demand server that consists of multiple clusters of nodes connected by a high performance interconnection network In order to e ciently control the ow of video streams we propose two scheduling algorithms for data retrieval and communica tion First we present a disk scheduling algorithm called round scheduling w...
متن کاملSymbolic Testing of OpenCL Code
We present an effective technique for crosschecking a C or C++ program against an accelerated OpenCL version, as well as a technique for detecting data races in OpenCL programs. Our techniques are implemented in KLEE-CL, a symbolic execution engine based on KLEE and KLEE-FP that supports symbolic reasoning on the equivalence between symbolic values. Our approach is to symbolically model the Ope...
