Deltas are growing centers of risk Population growth, urbanization, and rising sea levels placing populations living in delta regions under increased risk. The future resiliency potential for adaptation by these depend on a number socioeconomic geophysical factors. Tessler et al. examined 48 deltas from around the globe to assess changes regional vulnerability (see Perspective Temmerman). Some countries with high gross domestic product will be initially more resilient changes, because they...

We present fast methods for separating the direct and global illumination components of a scene measured by camera illuminated light source. In theory, separation can be done with just two images taken high frequency binary pattern its complement. practice, larger number are used to overcome optical resolution limitations The approach does not require material properties objects media in known. However, we that is enough adequately sample received points. results scenes include complex...

An image acquired by a camera consists of measured intensity values which are related to scene radiance function called the response function. Knowledge this is necessary for computer vision algorithms depend on radiance. One way has been determined establishing mapping between images taken with different exposures. We call In paper, we address two basic questions. What information from pair at exposures needed determine function? Given function, can and be determined? completely ambiguities...

Many vision applications require precise measurement of scene radiance. The function relating radiance to image intensity an imaging system is called the camera response. We analyze properties that all responses share. This allows us find constraints any response must satisfy. These determine theoretical space possible responses. have collected a diverse database real-world functions (DoRF). Using this database, we show occupy small part combine from our with data DoRF create low-parameter...

Many vision tasks such as scene segmentation, or the recognition of materials within a scene, become considerably easier when it is possible to measure spectral reflectance surfaces. In this paper, we present an efficient and robust approach for recovering in that combines advantages using multiple sources multispectral camera. We have implemented system based on cluster light with different spectra illuminate conventional RGB camera acquire images. Rather than sequentially activating...

Linear perspective projection has served as the dominant imaging model in computer vision. Recent developments image sensing make highly restrictive. This paper presents a general that can be used to represent an arbitrary system. It is observed all systems perform mapping from incoming scene rays photo-sensitive elements on detector. conveniently described using set of virtual called raxels. Raxels include geometric, radiometric and optical properties. We present novel calibration method...

The histogram of image intensities is used extensively for recognition and retrieval images video from visual databases. A single histogram, however, suffers the inability to encode spatial variation. An obvious way extend this feature compute histograms multiple resolutions an form a multiresolution histogram. shares many desirable properties with plain including that they are both fast compute, space efficient, invariant rigid motions, robust noise. In addition, directly encodes...

We present a method for controlling the appearance of an arbitrary 3D object using projector and camera. Our goal is to make one look like another by projecting carefully determined compensation image onto object. The determination appropriate requires accounting spatial variation in object's reflectance, effects environmental lighting, spectral responses, spatially varying fall-offs, non-linear responses projector-camera system. Addressing each these effects, we which calls estimation only...

Projection systems can be used to implement augmented reality, as well create both displays and interfaces on ordinary surfaces. Ordinary surfaces have varying reflectance, color, geometry. Current methods use a camera account for these variations, but are fundamentally limited since they assume the camera, projector, scene static. In this article, we describe technique photometrically adaptive projection that makes it possible handle dynamic environment. We begin by presenting co-axial...

Conventional vision systems and algorithms assume the camera to have a single viewpoint. However, sensors need not always maintain For instance, an incorrectly aligned system could cause non-single viewpoints. Also, be designed specifically deviate from viewpoint trade-off image characteristics such as resolution field of view. In these cases, locus viewpoints forms what is called caustic. this paper, we present in-depth analysis caustics catadioptric cameras with conic reflectors....

Projection systems can be used to implement augmented reality, as well create both displays and interfaces on ordinary surfaces. Ordinary surfaces have varying reflectance, color, geometry. These variations accounted for by integrating a camera into the projection system applying methods from computer vision. The currently applied are fundamentally limited since they assume camera, projector, scene static. In this paper, we describe technique photometrically adaptive that makes it possible...

A framework for analyzing distortions in non-single viewpoint imaging systems is presented. Such possess loci of viewpoints called caustics. In general, perspective (or undistorted) views cannot be computed from images acquired with such without knowing scene structure. Views structure will exhibit distortions, which we call caustic distortions. We first introduce a taxonomy based on the geometry systems. Then, derive metric to quantify present an algorithm compute minimally distorted using...
