2012 International Conference on Digital Image Computing: Techniques and Applications (DICTA)
he International Conference on Digital Image Computing: Techniques and Applications (DICTA) is the main Australian Conference on computer vision, image processing, pattern recognition, and related areas. DICTA was established as a biannual conference in 1991 and became an annual event in 2007. It is the premiere conference of the Australian Pattern Recognition Society (APRS).

Discrete transforms are used extensively in digital signal processing. The discrete Fourier transform (DFT) and other discrete transforms, such as discrete cosine transform (DCT), discrete Hartley transform (DHT), discrete combination Fourier transform (DCFT), real discrete Fourier transform (RDFT), have also been extensively studied and have a broad range of applications. We provide a unified framework for the above discrete transforms ...

Conventional Fourier analysis has many schemes for different types of signals. They are Fourier transform (FT), Fourier series (FS), discrete-time Fourier transform (DTFT), and discrete Fourier transform (DFT). The goal of this article is to develop two absent schemes of fractional Fourier analysis methods. The proposed methods are fractional Fourier series (FRFS) and discrete-time fractional Fourier transform (DTFRFT), and they ...

The performance of the parallel vector implementation of the 1D and 2D orthogonal transforms is evaluated. The orthogonal transforms are computed using actual or modified fast Fourier transform kernels. The factors considered in comparing the speed-up of these vectorized digital signal processing algorithms are discussed and it is shown that the traditional way of comparing the execution speed of digital ...
Ersoy, O.K. Proceedings of the IEEE, 1994
Major continuous-time, discrete-time, and discrete Fourier-related transforms as well as Fourier-related series are discussed both with real and complex kernels. The complex Fourier transforms, Fourier series, cosine, sine, Hartley, Mellin, Laplace transforms, and z-transforms are covered on a comparative basis. Generalizations of the Fourier transform kernel lead to a number of novel transforms, in particular, special discrete cosine, discrete sine, ...

The two-dimensional (2D) forward/inverse discrete Fourier transform (DFT), discrete cosine transform (DCT), discrete sine transform (DST), discrete Hartley transform (DHT), discrete Walsh-Hadamard transform (DWHT), play a fundamental role in many practical applications. Due to the separability property, all these transforms can be uniquely defined as a triple matrix product with one matrix transposition. Based on a systematic approach to represent ...
Behzad, Arya Wireless-LAN Radio Design, 2005
As one of the few rising stars of the semiconductor industry, WLAN design is engaging more and more engineers and companies. Essential to the overall system design, is the radio design. This tutorial will introduce the various flavors of the 802.11 WLAN PHY standards (A/B/G) and describe their specifications and impact on the radio design. The possible choices for the ...
O'Donnell, Robert Review of Signal Systems and Digital Signal Processing, 2012
The Radar Systems Engineering Series consists of seventeen lectures; each lecture is offered as an individual tutorial. The goal of this series is to provide an advanced introduction to radar systems subsystem issues for first year graduate students, advanced senior undergraduates or professionals new to the field. The material will be most accessible to university graduates with a Bachelor of ...
