Acceleration of a content-based image-retrieval application on the RDISK cluster

Abstract

Because of the growing use of multimedia content over Internet, Content-Based Image Retrieval (CBIR)

Coupled fixed point theorems for new contractive mixed monotone mappings and applications to integral equations

“…Fixed point theory is a very useful tool in various fields of mathematics, game theory, mathematical economics, statistics, biology, chemistry, engineering, computer science and economics in dealing with problems arising in approximation theory, theory of differential equations, theory of matrix equations etc. (see, [1][2][3][4][5][6][7]). For example, in theoretical economics, such as general equilibrium theory, there comes at point where one needs to know whether the solution to a system of equations necessarily exists; or, more specifically, under which conditions will a solution necessarily exist (see, [1]).…”

Combining flash memory and FPGAs to efficiently implement a massively parallel algorithm for content-based image retrieval

“…However, floating-point in FPGAs has major drawbacks in terms of performance and resources usage (Ligon III et al 1998, Govindu, Zhuo, Choi andPrasanna 2004). We have shown in Noumsi, Derrien and Quinton (2006) that using 8-bit fixed-point arithmetic for descriptor distance computation preserves the accuracy of the results.…”

“…In a previous work (Noumsi, Derrien and Quinton 2006), we proposed to accelerate the CBIR algorithm on a FPGA based smart-disk architecture (Guyetant et al 2005). While this approach provided interesting performance improvements, its efficiently was greatly affected by the limited sustained hard-disk throughput.…”

Content-based Image Retrieval Speedup

“…In PSB, a collection of pivots are used for representing semantics as well as multiple balls to cover more informative reference features in image which all are executed on GPU efciently. In [26], a method for CBIR acceleration was proposed on the RDISK machine. This machine uses the philosophy of smart-disks and is considered as a cluster of FPGA-enhanced hard-drives.…”
