Many real-time stereo vision systems are available on lowpower platforms. They all either use a local correlation-like stereo engine or perform dynamic programming variants on a scan-line. However, when looking at high-performance global stereo methods as listed in the upper third of the Middlebury database, the low-power real-time implementations for these methods are still missing. We propose...

Generating accurate three dimensional planetary models is becoming increasingly important as NASA plans manned missions to return to the Moon in the next decade. This paper describes a 3D surface reconstruction system called the Ames Stereo Pipeline that is designed to produce such models automatically by processing orbital stereo imagery. We discuss two important core aspects of this system: (...

Recently, the stereo imaging-based image enhancement approach has attracted increasing attention in the field of video analysis. This paper presents a dual camera-based stereo image defogging algorithm. Optical flow is first estimated from the stereo foggy image pair, and the initial disparity map is generated from the estimated optical flow. Next, an initial transmission map is generated using...

The High Resolution Stereo Camera (HRSC) on Mars Express covers the surface of our neighboring planet in full color and 3D. Altogether, nine channels are obtained in stereo angles between ±18.9°. These data sets are well suited to derive Digital Terrain Models (DTM) and, based on that, color orthoimages. Both, photogrammetric standard processing of HRSC data as well as alternative and/or supple...

Image processing is required in number of fields like clinical diagnosis, remote sensing and computer vision. The need for overlaying of images exists in image processing. Image registration is the basis step in various applications of image processing. Registration involves digital preprocessing of the images. It is an important component of various systems including matching a target with a r...

Simultaneous Geosynchronous Operational Environmental Satellite (GOES) 1 km resolution visible image pairs can provide quantitative three dimensional measurements of clouds. These data have great potential for severe storms research and as a basic parameter measurement source for other areas of meteorology (e.g. climate). These stereo cloud height measurements are not subject to the errors and ...

The GI-Eye GPS/inertial video system is design to support rapid collection and location of target coordinates through processing georeferenced digital video imager. Extracting coordinates from video imagery has historically required significant processing to determine the relative position and orientation of stereo image pairs (through photogrammetry) or the use of expensive fixedbase stereo vi...

This white paper compares two different hardware platforms for stereo image processing systems. It discusses their advantages and disadvantages along with other factors for consideration. It then looks at how these approaches are implemented in actual products.
