This paper presents a novel approach to finding point correspondences between images of building facades with wide viewpoint variations, and at the same time returning a large list of true matches between the images. Such images comprise repetitive and symmetric patterns, which render popular algorithms e.g., SIFT to be ineffective. Feature descriptors such as SIFT that are based on region patches...
We propose a new effective shape descriptor, chord context, for shape description in content-based image retrieval. For a shape, the chord context describes a frequency distribution of chord lengths with different orientations. The histograms which represent the chord context are compacted and normalized into a feature matrix. Unlike other shape representation schemes, the proposed scheme is able...
The method of using pre-defined models to extract spatial information of man-made object digital image is called model-base object extraction, which has been a convincible approach to improve the existing Photogrammetry techniques. This paper used a semi-automated approach to extracting buildings from single aerial image by the Least-squares model-image fitting (LSMIF) algorithm. Each CAD model is...
