    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.

    摘要: One embodiment of the invention provides a system that facilitates identifying line-end features in a layout for an integrated circuit. The system operates by first receiving the layout for the integrated circuit. Next, the system selects a polygon from the layout and marks a line-end seed on the polygon. The system then determines if the line-end seed is associated with a line feature, and if so, the system marks the line-end feature inside the line feature.
