چکیده

This paper presents for the first time a method to evaluate the performance of local detectors under viewpoint changes on complex, realistic, and practically relevant scenes. The main contribution is a method which allows the automatic verification of detected corresponding points and regions for non-planar scenes. Using this method the performances of 10 different local detectors were evaluated in a large scale experiment. A ranking of the different detectors has been established based on this evaluation.

On Viewpoint Invariance for Non-Planar Scenes

Most local feature detectors/descriptors implicitly assume that the scene is (locally) planar, an assumption that is violated at surface discontinuities. We show that this restriction is, at least in theory, un-necessary, as one can construct local features that are viewpoint-invariant for generic non-planar scenes. However, we show that any such feature necessarily sacrifices shape information...

Evaluation of Interest Point Detectors for Non-planar, Transparent Scenes

The detection of stable, distinctive and rich feature point sets has been an active area of research in the field of video and image analysis. Transparency imaging, such as X-ray, has also benefited from this research. However, an evaluation of the performance of various available detectors for this type of images is lacking. The differences with natural imaging stem not only from the transpare...

A revised evaluation framework for region of interest detectors using artificial 3d-scenes

In this project, we introduce an evaluation method for regions of interest detectors in images of general 3d-scenes addressing some issues of the framework by Mikolajczyk et al. (2005) and the extension to non-planar scenes by Fraundorfer and Bischof (2005). By generating more reliable ground truth and test images from detailed POV-Ray scenes, we were able to take the influence of discontinuiti...

Performance Evaluation of Local Detectors in the Presence of Noise for Multi-Sensor Remote Sensing Image Matching

Automatic, efficient, accurate, and stable image matching is one of the most critical issues in remote sensing, photogrammetry, and machine vision. In recent decades, various algorithms have been proposed based on the feature-based framework, which concentrates on detecting and describing local features. Understanding the characteristics of different matching algorithms in various applications ...
