    This correspondence discusses an extension of the well-known phase correlation technique to cover translation, rotation, and scaling. Fourier scaling properties and Fourier rotational properties are used to find scale and rotational movement. The phase correlation technique determines the translational movement. This method shows excellent robustness against random noise View full abstract»

    The paper describes a lossy image codec that uses a noncausal (or bilateral) prediction model coupled with vector quantization. The noncausal prediction model is an alternative to the causal (or unilateral) model that is commonly used in differential pulse code modulation (DPCM) and other codecs with a predictive component. We show how to obtain a recursive implementation of the noncausal image mo... View full abstract»

    We investigate the design of lapped orthogonal transforms for data compression of images. We present some properties and new results of paraunitary filter banks. We concentrate on the case where the filter length L=2K, where K is the number of channels. The aim is to design perceptually relevant filters, i.e., linear-phase filters that smoothly decay to zero at the boundaries View full abstract»

    This correspondence addresses the problem of maximizing the subjective picture quality at given bit rates for coded video. Coding is carried out using different picture formats. The parameters involved are the number of pixels horizontally and vertically and interlacing/noninterlacing. The coding is done according to the MPEG-2 standard View full abstract»

  • Reconnaissance with slant plane circular SAR imaging

    This paper presents a method for imaging from the slant plane data collected by a synthetic aperture radar (SAR) over the full rotation or a partial segment of a circular flight path. A Fourier analysis for the Green's function of the imaging system is provided. This analysis is the basis of an inversion for slant plane circular SAR data. The reconstruction algorithm and resolution for this SAR sy... View full abstract»

  • A method for rectifying grid junctions in grid-coded images using cross ratio

    In the grid-coding technique, the accurate grid junction locations are vital to the surface computation. Noise arising from the imaging formation and processing processes will jeopardize the computation accuracy. The objective of this study is to make use of the geometric property of cross ratio to improve the accuracy of grid junction locations in grid-coded images. A method is devised to regener...

  • Recovery of surfaces with discontinuities by fusing shading and range data within a variational framework

    This work provides a variational framework for fusing range and intensity data for recovering regularized surfaces. It is shown that this framework provides natural boundary conditions for the shape-from-shading problem, results in a new shape-from-shading formulation in the absence of range data, and provides a new fusion paradigm when range data is incorporated. The approach is demonstrated on s... View full abstract»
