摘要： A novel, easy to use, and computational efficient rubber sheeting algorithm is designed for interactive image registration in a web-based application environment. The algorithm has two steps, including a piece-wise linear interpolation step to interactively find a suitable set of control points and displacement vectors, and a following optional global radial basis wrap step to generate smoother result using the final control point set. A dynamic Delaunay triangulation method is designed to efficiently update the decomposition of the image. Natural and intuitive wrapping result will be dynamically generated in real-time while the user interactively insert, delete or drag a control point. The number of control points is not limited, and a large number of control points can be used if necessary without compromising the performance of the algorithm. With enough control points specified using the piece-wise rubber-sheeting step, the wrapping result can be further smoothed by using the optional, click-button poly-quadric global wrapping method in the second step. The algorithm is implemented as a Java Applet and able to run as a cross-platform web-based application.

摘要： The present invention relates to methods for aligning raster and vector data. In an embodiment, a raster/vector aligner receives raster data and an approximate vector of a feature within the raster data. The raster/vector aligner generates an edge signal by edge filtering the raster data along a direction of the approximate vector and a smoothness signal by smoothness filtering the raster data along a direction of the approximate vector. The raster/vector aligner combines the edge signal and the smoothness signal into a combined signal which is used to generate a translation vector or a signal weight for the feature within the raster data.

摘要： Embodiments determine the species of trees present in an aerial image. Tree crowns are detected in a received image, and represented as histograms of their color, texture and entropy features. Similar trees are clustered together. Using classification techniques, each cluster is assigned the closest species. The species information for each tree may be used in a rendering of the tree in geographical information systems.
