Fast Am-fm Demodulation Image and Video Analysis Using Single Instruction Multiple Data (simd) Architectures
نویسندگان
چکیده
AM-FM demodulation is used for expanding a digital image/video in terms of an AM-FM series expansion. The fundamental AM-FM harmonic is estimated using a collection of bandpass filters which operate over the analytic version of the input image/video. The SIMD architecture was used to develop a fast implementation of the AM-FM decomposition. Preliminary results are shown for a novel fast segmentation of M-mode ultrasound videos, based only on the harmonic estimation.

In this chapter, we present contemporary VLSI processor architectures that support multimedia applications. We classified these processors into two groups: dedicated multimedia processors, which perform dedicated multimedia functions, such as MPEG encoding or decoding, and general-purpose processors that provide support for multimedia. Dedicated multimedia processors use either function-specifi...

The paper presents a study on the impact of using SIMD (Singe Instruction Multiple Data) techniques and architectures in low level image processing. Speedups obtained on a SIMD parallel architecture (IMAPVISION board) and a single Intel MMX processor computer are presented for different low-level image processing operators. While the IMAP-Vision system performs better because of the large numbe...

PROVIDING VIDEO-OVER-WIRELESS capability to mobile-computing platforms results in several interesting challenges. Wireless networks provide less transmission bandwidth than hard-wired networks. Because today’s wireless local-areanetwork technology can provide only around 2-Mbps transmission rates, video compression is essential for transmitting to mobile devices. Due to increased user sensitivi...
متن کاملSoftware Based MEPG-2 Encoding System with Scalable and Multithreaded Architecture
MPEG-2 video encoders are now available in a variety of forms using both hardware and software based approaches. The software-based approach potentially offers a better picture quality but is computationally quite intensive. MPEG-2 video encoding can be fast processed using parallelism. A number of approaches using parallel machines or networks of workstations have been reported. While these ap...
متن کاملImplementation of fast HEVC encoder based on SIMD and data-level parallelism
This paper presents several optimization algorithms for a High Efficiency Video Coding (HEVC) encoder based on single instruction multiple data (SIMD) operations and data-level parallelism. Based on the analysis of the computational complexity of HEVC encoder, we found that interpolation filter, cost function, and transform take around 68% of the total computation, on average. In this paper, se...
