I shall talk about building 3D models from image sequences, and inparticular about rendering new views of existing sequences in orderto create stereoscopic 3D from monocular footage. I shall show howexisting strategies for image-based rendering can be augmented usingimage-based priors to create realistic 3D views. In addition I willtalk about th...

I will present a survey of recent results on geometry-based image processing. The topics will include wavelet-based diffuse interface methods, pan sharpening and hyperspectral sharpening, and sparse image representation.

Many imaging techniques acquire information about an underlying image by making indirect linear measurements. For example, in computed tomography we observe line integrals through the image, while in MRI we observe samples of the image's Fourier transform.To acquire an N-pixel image, we will in general need to make at least N measurements.What h...

Traditional optical design typically exploits only limitedprior knowledge of the object space to be imaged (e.g., resolution, field of view, nominal range, etc.) It is possibleto include stronger object space constraints (e.g., specificobjects of interest, operational SNR, background characteristics, etc.) into the optical design and thus genera...

One can trade off complexity in imaging system hardware and strictsystem tolerances for complexity in post-detection data processing.We describe an extreme example in this trade-off space: a coherentimaging approach that eliminates the imaging system hardware entirely(except for the detector array), relying on a phase retrievalalgorithm to form ...

Joint with Gaik Ambartsoumian.In thermoacoustic tomography TAT (sometimes called TCT), one triggersan ultrasound signal from the medium by radiating it with a short EM pulse. Mathematically speaking, under ideal conditions, the imaging problem boils down to inversion of a spherical Radon transform. The talk will survey known results and open pro...

Processing information at the sensor level can not only help reduce theamount of data acquired but also enhance the overall performance of thesystem. In this talk I will first present methods for shaping thethree-dimensional response of an optical system. Then I will discuss howto integrate tailored optical responses with digital postprocessinga...

We present some of our recent work on coherent image reconstruction.The primary application that has driven this work has been syntheticaperture radar, although we have extended our approach to othermodalities such as ultrasound imaging as well. One of the motivationsfor our work has been the increased interest in using reconstructedimages in au...

Image-based rendering has been one of the hottest areas in computergraphics in recent years. Instead of using CAD and painting tools toconstruct graphics models by hand, IBR uses real-world imagery torapidly create extremely photorealistic shape and appearancemodels. However, IBR results to date have mostly been restricted tostatic objects and s...

A new form of coherent optical microscopy is described thatgenerates images (reconstructions) of two and three-dimensional,penetrable scatteringobjects computationally from sets of measured digital hologramsof scattered field data collected in a suite of scatteringexperiments. Themicroscope uses the technique of 'phase shifting holography'(expla...
