摘要： A block-base error measure method for object segmentation includes the steps of dividing a reference image having an object into plural non-overlapping blocks, superimposing the reference image with a segmented image to obtain an error ratio of the block to define an enhanced equation and a modification equation to suppress the scattered error and enhance the contribution of the region error, so as to calculate the error amount of the segmented image and evaluate the performance of image segmentation. Compared with the conventional error measure method based on pixels, the present invention provides a more accurate high-level semantic.

摘要： Example embodiments include a method that reduces consumption of computer resources in a computer system to reconstruct a shape of a multi-object image using finite terms. The method includes computing an initial function by performing V-system of degree 0 and functions of curves by performing hierarchical V-system. Norms of the functions of curves are compared with a predetermined threshold. A reconstruction function of the shape of the multi-object image is generated by summing the initial function and the functions of curves.

摘要： Techniques of data compression involve ordering the points of a point cloud according to distance along a space-filling curve. Advantageously, a space-filling curve has the property that points close in distance along the curve are close together in Euclidean space. Thus, differences between points ordered by distance along such a curve, e.g., a Hilbert curve, will be close. When the curve is fractal, i.e., self-similar at all levels, the differences will be small even when the points are very unevenly clustered throughout the point cloud. Such small differences will provide greatly improved compression to the resulting delta-encoded set of points.

摘要： Systems, methods, and computer-readable media are disclosed for constructing fonts from scanned images. In one embodiment, a method may include receiving a scanned image with a first glyph and a second glyph that correspond to a character in the image. The method may include generating an image representative of each of the first glyph and the second glyph, determining a default positioning of the first character, determining a positional reference line indicative of an alignment of certain characters, and a third positional reference line indicative of an alignment of different characters. The method may include determining an adjustment for the first glyph by determining a distance between the default positioning and the second positional reference line. The method may include assigning an identifier to the first glyph and generating a font file to be executed by a renderer for rendering the source text.

摘要： In one embodiment, data of a data set that describes the topography of a three-dimensional surface (e.g., a DTM) is obtained at a resolution appropriate for visualization on a display screen. The data is organized into a number of resolutions by spatial indexing. A lowest resolution cluster of data is selected. For any visible data in the selected cluster of data for a type of visualization to be shown on the display screen, a point density in a coordinate system of the display screen resulting from data is compared to a configured threshold. If the point density in the display screen's coordinate system is below the configured threshold, visible data in the selected cluster of data is returned for display. If the point density in the display screen's coordinate system is above the configured threshold, one or more next-higher resolution clusters of data are selected, and the technique repeated.

摘要： A method for labeling a segment of a two-dimensional input path defined according to a nonzero winding rule as either interior or exterior is described. A winding number is initialized. A scan line that intersects the segment is identified. For each contour of the input path, winding values are accumulated into the winding number for any segments of the contour that cross the identified scan line, where the accumulation for coincident segments that cross the identified scan line at a same location as the segment is postponed. These coincident segments are marked and saved in a list. The labeling of the segment as either interior or exterior is determined from the list and the winding number.
