Fast linear canonical transforms.
The linear canonical transform provides a mathematical model of paraxial propagation though quadratic phase systems. We review the literature on numerical approximation of this transform, including discretization, sampling, and fast algorithms, and identify key results. We then propose a frequency-division fast linear canonical transform algorithm comparable to the Sande-Tukey fast Fourier tran...
متن کاملTop-Down Control of Visual Attention: A Rational Account
Theories of visual attention commonly posit that early parallel processes extract conspicuous features such as color contrast and motion from the visual field. These features are then combined into a saliency map, and attention is directed to the most salient regions first. Top-down attentional control is achieved by modulating the contribution of different feature types to the saliency map. A ...
متن کاملNon-linear views in top-down games
Visualising objects of wildly differing scales, such as the contents of the Solar System, is a trade-off between accuracy and overview. The various existing solutions used in top-down games may have unwanted side effects on the resulting gameplay. We present a new solution based on treemaps placed in a spatial hierarchy that is capable of visualising these objects while maintaining the immersio...
متن کاملOptical implementations of two-dimensional fractional fourier transforms and linear canonical transforms with arbitrary parameters.
We provide a general treatment of optical two-dimensional fractional Fourier transforming systems. We not only allow the fractional Fourier transform orders to be specified independently for the two dimensions but also allow the input and output scale parameters and the residual spherical phase factors to be controlled. We further discuss systems that do not allow all these parameters to be con...
متن کاملthe impact of explicit instruction of top-down reading strategies on reading comprehension of intermediate efl learners
this study investigated (a) the learners’ existing reading strategy repertoire, (b) the effect of instruction in reading strategies on learners’ strategic performance, and (c) the effect of explicit instruction in top-down reading strategies on reading comprehension ability of intermediate learners. the study was conducted with 40 intermediate efl learners in two groups of experimental and cont...
