摘要： A code verification system is described herein that provides augmented code review with code clone analysis and visualization to help software developers automatically identify similar instances of the same code and to visualize differences in versions of software code over time. The system uses code clone search technology to identify code clones and to present the user with information about similar code as the developer makes changes. The system may provide automated notification to the developer or to other teams as changes are made to code segments with one or more related clones. The code verification system also helps the developer to understand architectural evolution of a body of software code. The code verification system provides an analysis component for determining architectural differences based on the code clone detection result between the two versions of the software code base. The code verification system also provides a user interface component for displaying identified differences to developers and others involved with the software development process in intuitive and useful ways.

摘要： Techniques for error report processing are described herein. Error reports, received by a developer due to program crashes, may be organized into a plurality of “buckets.” The buckets may be based in part on a name and a version of the application associated with a crash. Additionally, a call stack of the computer on which the crash occurred may be associated with each error report. The error reports may be “re-bucketed” into meta-buckets to provide additional information to programmers working to resolve software errors. The re-bucketing may be based in part on measuring similarity of call stacks of a plurality of error reports. The similarity of two call stacks—a measure of likelihood that two error reports were caused by a same error—may be based in part on functions in common, a distance of those functions from the crash point, and an offset distance between the common functions.

摘要： Described herein is technology for, among other things, accessing error report information. It involves various techniques and tools for analyzing and interrelating failure data contained in error reports and thereby facilitating developers to more easily and quickly solve programming bugs. Numerous parameters may also be specified for selecting and searching error reports. Several reliability metrics are provided to better track software reliability situations. The reliability metrics facilitate the tracking of the overall situation of failures that happen in the real word by providing metrics based on error reports (e.g., failure occurrence trends, failure distributions across different languages).

摘要： In accordance with embodiments of the invention, local metadata is embedded into an embedded interactive code document by combining a first m-array and a second m-array to generate a combined m-array with encoded local metadata such that a start position of the second m-array in the combined m-array is shifted, by an amount that is based on the local metadata, relative to a start position of the first m-array in the combined m-array. The first m-array and the second m-array may contain the same repeating bit sequence. Local metadata may be decoded from the embedded interactive code document by decoding the local metadata from the combined m-array by determining the amount by which the second m-array is shifted, relative to the first m-array, in the combined m-array.

摘要： A technique is disclosed for determining a portion of a document corresponding to a captured image. A user employs a pen to create a stroke in a document, and images are captured by a camera mounted on the pen. The locations of some of the images are determined by, e.g., analyzing a pattern on the document captured by the image or by a pixel-by-pixel comparison of the image with the document. The locations of other images are determined by segmenting the sequence of images into groups corresponding to the shape of the stroke. Information relating to a located image in a segment is employed to determine the position of an unlocated image in the segment. This determined position is used for obtaining further information that may be used to determine the position of another unlocated image in the segment, and so on, until the segment is finished.

摘要： Pre-processing techniques for processing an image to improve the distinctiveness of an information pattern captured in the image before the information pattern is analyzed in a decoding process. The brightness of an image first is normalized by dividing the image into blocks of areas, such as pixels. A brightness distribution value then is determined for each area of the image by fitting the brightness of its surrounding blocks using bilinear interpolation and extrapolation, and a normalized brightness value for each area can then be obtained by dividing the original brightness value by the brightness distribution value. Next, masks are created to distinguish the information pattern from content captured in the image. The masks may be generated based upon contrast differences between the brightness of pixels representing the information pattern, the brightness of pixels representing content, and the brightness of pixels representing the background of the writing medium.

摘要： Processes and apparatuses analyze an image of a maze pattern in order to extract bits encoded in the maze pattern by iteratively obtaining a perspective transform from the captured image plane to the paper plane. The embedded interactive data is recognized by obtaining a perspective transform between the captured image plane and paper plane based on an obtained affine transform. The perspective transform typically models the relationship between two planes more precisely than the affine transform. The number of error bits in the extracted bit matrix is typically reduced, thus enabling decoding of position information to be more efficient and robust.

摘要： A method and apparatus for performing EIC pattern analysis is described. Pattern feature extraction is performed followed by EIC symbol segmentation. A system may later use the result from the pattern analysis to determine a location of a captured image in relation to a larger array of EIC symbols.
