  • Publication number: 20110250571
    Abstract: A computer-implemented method for teaching math is disclosed. The method comprises displaying a number line graphic to indicate a relative order between numbers; generating a first problem comprising numbers at least some of which are indicated on the number line graphic; selectively providing guidance for solving the problem; and receiving a user's input as a solution to the first problem.

  • Publication number: 20110250574
    Abstract: A computer-implemented method for teaching math is disclosed. The method comprises generating a problem for a user to solve; generating a graphical representation of a number associated with the problem; wherein the graphical representation is selected to facilitate subitizing of the number; and overlaying visual guidance on the graphical representation to guide a user as a means to drawing attention to a learning strategy for solving the problem; receiving and checking a user's input as a solution to the problem; and indicating to the user a correctness of the solution.

  • Publication number: 20110044515
    Abstract: A device, system and method for automatic detection of contractile activity of a body lumen in an image frame is provided, wherein image frames during contractile activity are captured and/or image frames including contractile activity are automatically detected, such as through pattern recognition and/or feature extraction to trace image frames including contractions, e.g., with wrinkle patterns. A manual procedure of annotation of contractions, e.g. tonic contractions in capsule endoscopy, may consist of the visualization of the whole video by a specialist, and the labeling of the contraction frames. Embodiments of the present invention may be suitable for implementation in an in vivo imaging system.

  • Publication number: 20100046816
    Abstract: A method for automatically detecting a post-duodenal boundary in an image stream of the gastrointestinal (GI) tract. The image stream is sampled to obtain a reduced set of images for processing. The reduced set of images is filtered to remove non-valid frames or non-valid portions of frames, thereby generating a filtered set of valid images. A polar representation of the valid images is generated. Textural features of the polar representation are processed to detect the post-duodenal boundary of the GI tract.

  • Publication number: 20090284589
    Abstract: A method and system cascade analysis for intestinal contraction detection is provided by extracting from image frames captured in-vivo. The method and system also relate to the detection of turbid liquids in intestinal tracts, to automatic detection of video image frames taken in the gastrointestinal tract including a field of view obstructed by turbid media, and more particularly to extraction of image data obstructed by turbid media.

  • Publication number: 20090202117
    Abstract: A method and system for determining intestinal dysfunction condition are provided by classifying and analyzing image frames captured in-vivo. The method and system also relate to the detection of contractile activity in intestinal tracts, to automatic detection of video image frames taken in the gastrointestinal tract including contractile activity, and more particularly to measurement and analysis of contractile activity of the GI tract based on image intensity of in vivo image data.
