SRI’s Digital Earth Project
The goal of SRI International’s Digital Earth project was to develop the infrastructure for an open, distributed, multiresolution, 3-D representation of the earth, into which massive quantities of georeferenced information…

Lightweight solutions for user interfaces over the WWW
We present some lightweight tools that have been essential in producing applications with complex interactive interfaces.

Detecting Changes in 3-d Shape using Self-Consistency
A novel image-matching measure based on Minimum Description Length (MDL) theory allows us to estimate the accuracy of individual elements of the 3- D model. Experiments to demonstrate the utility…

Self-Consistency, A Novel Approach to Characterizing the Accuracy and Reliability of Point-Correspondence Algorithms
We present a framework for reliably and robustly detecting changes in terrain (or other 3-D objects) over time.
-
A Framework for Detecting Changes in Terrain
We propose a methodology that estimates the accuracy and reliability of the results of any multiple-image point correspondence algorithm, without the need for ground truth or camera calibration.

Using Differential Constraints to Reconstruct Complex Surfaces from Stereo
Stereo reconstruction algorithms often fail to properly deal with complex surfaces, because there is not enough image information. We propose to guide the reconstruction process using a priori information about…

Object-Centered Surface Reconstruction: Combining Multi-Image Stereo and Shading
We argue that an object-centered representation is most appropriate for this purpose becasue it naturally accomodates multiple sources of data, multiple images (including motion sequences of a rigid object), and…

Registration without Correspondences
We present a method for registering images of complex 3-D surfaces that does not require explicit correspondences between features across the images.

Using 3-Dimensional Meshes to Combine Image-Based and Geometry Constraints
A unified framework for 3-D shape reconstruction allows us to combine image-based and geometry-based information sources. The image information is akin to stereo and shape-from-shading, while the geometric information may…

Learning Control Parameters of a Vision Process Using Contextual Information
This paper presents a method for the system itself to learn how to select among its algorithms and to set their parameters, reducing the need for operator expertise while improving…

Building and Using Scene Repesentations In Image Understanding
The analysis side is the processing of sensory data for such tasks as recognition and navigation, and a number of techniques are discussed here for dealing with these two-, three-,…

Overview Of The SRI Cartographic Modeling Environment
The SRI Cartographic Modeling Environment has been created to support research on interactive, semi-automated, and automated computer-based cartographic activities. The underlying image manipulation capabilities are provided by the SRI ImagCalc…
