In this paper, balanced two-stage residual networks (BTSRN) are proposed for single image super-resolution. The deep residual design with constrained depth achieves the optimal balance between the accuracy and the speed for super-resolving images. The experiments show that the balanced two-stage structure, together with our lightweight two-layer PConv residual block design, achieves very promising...
FPGA is fit for large parallel programs. To improve the performance of EULER3D program, a PC+FPGA solution based on system generator was practiced. Based on the analysis of the algorithm's hotspot, a system model was built for EULER3D kernel algorithm constructed with system generator blocks. The data exchange between the PC and the FPGA board used the Gigabit Ethernet MAC interface, and the overall...
This paper presents a novel approach, based on static analysis, to detect format string vulnerabilities in C programs. Format string vulnerability is viewed as a finite state safety property. The analysis is expressed as a system of constraint describing how the safety state at one program point is related to the state at adjacent program points. Our analysis is inter-procedurally flow sensitive and...
An efficient background modeling technique is a key step in surveillance or video content processing systems such as event detection, human action recognition and semantic indexing of video. In this paper, a simple but efficient modeling scheme, which is able to deal with static and dynamic backgrounds, is presented. First, each pixel is averaged by a group of dominant bins based on histogram analysis,...
As multiprocessor system-on-chip (MPSoC) approaches become popular in embedded system designs, simulation tools for modelling these systems are highly in demand for evaluating the performance and cost at both hardware design stage and software development phase. This paper presents a fast, flexible, and cycle-accurate simulation tool for MPSoCs targeting emerging dynamically reconfigurable processors...
A novel algorithm is proposed for solving the overlapped marker matching issues and satisfying speed requirement in a 3D video motion capture system. Firstly, the mean markers' longitudinal coordination difference in two parallel cameras is calculated to reduce 3D matching error. Secondly, the epipolar geometry restriction is used to make the corresponding marker be restricted in a line. Finally,...
