Introduction: The Mars Orbital Laser Altimeter (MOLA) has significantly advanced the study of the Martian surface by providing geologists with a highly accurate elevation map of the entire planet [1]. However, its limited resolution (463m/pixel at the equator) and localized interpolation artifacts have rendered it insufficient for detailed studies of specific sites; e.g. geologic stratification...

By using mirror reflections of a scene, stereo images can be captured with a single camera (catadioptric stereo). Single camera stereo provides both geometric and radiometric advantages over traditional two camera stereo. In this paper; we discuss the geometry and calibration of catadioptric stereo with two planar mirrors and show how the relative orientation, the epipolar geometry and the esti...

To navigate many-to-many mappings between referents and linguistic expressions, listeners need to calibrate likelihood estimates for different referential expressions taking into account both the context and speaker-specific variation. Focusing on speaker variation, we present three experiments. Experiment 1 establishes that listeners generalize speakerspecific patterns of pre-nominal modificat...

In stereo vision, an omnidirectional camera has high distortion compared to a standard camera, so the calibration is very decisive in its matching. this study, we will perform matching for with vertical and horizontal configuration that result of image's depth 360-degree field view by transforming image using calibration-based method. The configuration, can be matched directly, but configuring ...

OF THESIS 3D RECONSTRUCTION FROM STEREO/RANGE IMAGES. 3D reconstruction from stereo/range image is one of the most fundamental and extensively researched topics in computer vision. Stereo research has recently experienced somewhat of a new era, as a result of publically available performance testing such as the Middlebury data set, which has allowed researchers to compare their algorithms again...

This paper i s concerned with estimation of the reflectance map and i t s use in surface shape estimation by a method that combines stereo and shading information. There are many advantages t o the integrated approach. However, shape f rom shading algorithms are limited in their applicability by ihe assumption of idealized reflectance and lighting models involving many preset or hard t o estima...

One of the bottlenecks of current recognition (and graph matching) systems is their assumption of one-to-one feature (node) correspondence. This assumption breaks down in the generic object recognition task where, for example, a collection of features at one scale (in one image) may correspond to a single feature at a coarser scale (in the second image). Generic object recognition therefore req...

Semantic matching is a fundamental step in implementing data sharing applications. Most systems automating this task however limit themselves to finding simple (one-to-one) matching. In fact, complex (many-to-many) matching raises a far more difficult problem as the search space of concept combinations is often very large. This article presents Indigo, a system discovering complex matching in t...

In this paper, we address the problem of planning the textual organization of instructions. We take the view that natural language generation (NLG) is a mapping process of diierent levels of conceptual and textual representations. Within this framework , we consider the mapping between the text's semantic representation and its rhetorical structure. We argue that such a mapping is not direct, b...
