摘要： Conversion of text-based images to vector graphics (VG) is disclosed. The text-based images may include images of equations, custom typefaces, or other types of text that may not be included in a font selection of an optical character recognition (OCR) device or an application stored on a viewing device. A textual image may be converted from a raster graphics (RG) image to a VG image, which may enable resizing and alignment of the VG image with body text. In some aspects, the server may determine a body size of a reference character in the VG image. The server may determine a baseline of the VG image that may be used to align the image with the body text.

摘要： An image coding apparatus divides a picture into tiles. The tiles are coded to generate pieces of coded data, each of which corresponds to a different one of the tiles. In this regard, a first tile of the tiles is coded with reference to coding information of an already-coded tile neighboring the first tile when a boundary between the first tile and the already-coded tile is a first boundary. The first tile is coded without reference to the coding information of the already-coded tile when the boundary between the first tile and the already-coded tile is a second boundary. A bitstream including the pieces of coded data is generated. The bitstream includes tile boundary independence information which indicates whether each boundary between the tiles is one of the first boundary and the second boundary.

摘要： Matching processing between pieces of vector data is accelerated. A matching device 100 performs, for a plurality of pieces of vector data each having a plurality of dimensions, a predetermined operation pertaining to each dimension of each piece of vector data. The matching device 100 includes a collective operation unit 150 and an individual operation unit 160. The collective operation unit 150 performs the predetermined operation pertaining to a specific dimension among the plurality of dimensions by a vector operation for different pieces of vector data in the plurality of pieces of vector data. The individual operation unit 160 performs the predetermined operation pertaining to each dimension other than the specific dimension for a piece of vector data that satisfies a predetermined condition among the plurality of pieces of vector data.

摘要： Automatic characterization or categorization of portions of an input multispectral image based on a selected reference multispectral image. Sets (e.g., vectors) of radiometric descriptors of pixels of each component of a hierarchical representation of the input multispectral image can be collectively manipulated to obtain a set of radiometric descriptors for the component. Each component can be labeled as a (e.g., relatively) positive or negative instance of at least one reference multispectral image (e.g., mining materials, crops, etc.) through a comparison of the set of radiometric descriptors of the component and a set of radiometric descriptors for the reference multispectral image. Pixels may be labeled (e.g., via color, pattern, etc.) as positive or negative instances of the land use or type of the reference multispectral image in a resultant image based on components within which the pixels are found.

摘要： A method for encoding vertex orientations, also known as normal components, of a 3D mesh model comprises a first clustering of the normal components, determining for each of the first clusters a sphere sector to which most of its elements belong, mapping normal components to a predefined sector, re-clustering the normal components in the predefined sector into second clusters, determining predictors for the second clusters and encoding a normal component by its residual, a reference to its predictor and data indicating which of said mirror mapping operations were performed. A sphere sector is obtained by dividing a sphere into m equal spherical segments and dividing each of said spherical segments into n equal sectors. The first clustering for the sector mapping and the second clustering for predictive coding result in an improved compression ratio.

摘要： Data representing animated hair in a computer generated imagery (CGI) scene may be compressed by treating hair data as arrays of parameters. Hair data parameters may include control vertices, hair color, hair radius, and the like. A principal component analysis (PCA) may be performed on the arrays of hair data. PCA may yield new basis vectors, varying in length, with the largest basis vector corresponding to a new dimension with the largest variance in hair data. The hair data may be quantized based on the varying lengths of new basis vectors. The number of bits allocated for quantizing each new dimension corresponding to each new basis vector may be determined based on the relative lengths of new basis vectors, with more bits allocated to dimensions corresponding to longer basis vectors. The quantized hair data may be bit-packed and then compressed using lossless entropy encoding.
