Publication number: 20140219565Abstract: Disclosed is a handwriting recognition system with a plurality of input modes, including a storage unit, a touch screen display unit, and a processing unit. The storage unit stores character fonts; each of the character fonts corresponds to at least one of the input modes. The touch screen display unit includes an input panel having at least two input areas located thereon; each of the areas inputs data in one of the input modes. The processing unit judges an input set of touch signals to recognize a character input by handwriting in one of the input modes, according to a position on which one of the input areas, which position corresponds to at least one of the set of touch signals. The character is represented by the set of touch signals. A handwriting recognition method applicable to an electronic apparatus with a plurality of input modes is also provided.Type: ApplicationFiled: January 29, 2014Publication date: August 7, 2014Applicants: Inventec Appliances (Pudong) Corporation, INVENTEC APPLIANCES (SHANGHAI) CO.,LTD., INVENTEC APPLIANCES CORP.Inventor: CHIA CHUNG LEE

Publication number: 20140219566Abstract: Cell phones and other portable devices are equipped with a variety of technologies by which existing functionality can be improved, and new functionality can be provided. Some relate to visual search capabilities, and responding to different image inputs and different contexts. Others relate to processing of image data. Still others concern metadata generation, processing, and representation. Yet others relate to coping with fixed focus limitations of cell phone cameras, e.g., in reading digital watermark data. Still others concern user interface improvements. Yet others concern adapting behavior of a camera-equipped system based on previously-captured imagery. A great number of other features and arrangements are also detailed.Type: ApplicationFiled: November 20, 2013Publication date: August 7, 2014Applicant: Digimarc CorporationInventors: Tony R.

Publication number: 20140219568Abstract: A method for automated user information provision using an image includes requesting at least one user information image in response to receiving a user information form from a requesting entity over a network. The at least one user information image is received from a camera. The at least one user information image is analyzed using a processor to determine that the at least one user information image includes requested user information in at least one request section of the user information form. The requested user information is automatically provided into the at least one request section of the user information form. The user information form including the requested user information in the at least one request section is displayed on a display. The user information form may then be sent over the network to provide the requested user information to the requesting entity.Type: ApplicationFiled: April 23, 2014Publication date: August 7, 2014Applicant: EBAY INC.Inventor: Carl B.

Publication number: 20140219569Abstract: Embodiments for determining the similarity of different images are generally described herein. In some embodiments, image features of different images are converted to clusters, the clusters from each image are sorted based on one or more attributes of the clusters, and a plurality of three-point sets are generated for each image from a selected portion of the sorted clusters. Each three-point set defines a triangle. Matching triangles may be identified from the different images. The corresponding clusters of the matching triangles represent corresponding image features providing for a measure of the similarity of the two different images.Type: ApplicationFiled: February 7, 2013Publication date: August 7, 2014Applicant: Raytheon CompanyInventors: Steven James Manson, Tara L.

Publication number: 20140219570Abstract: Generating an analysis of a motion is disclosed. A first computing device receives image data that includes a set of user images. Each user image in the set corresponds to a stage of a plurality of consecutive stages of the motion and depicts a user at the corresponding stage. For each stage of the plurality of consecutive stages, a plurality of motion point locations in the corresponding user image is determined. Based on the plurality of motion point locations and reference motion data associated with a reference motion, a user motion report is generated.Type: ApplicationFiled: March 15, 2013Publication date: August 7, 2014Applicant: COLEY SPORTS AND ENTERTAINMENT LLCInventors: Tyson Hanish, Robert Schulte, Richard Davis

Publication number: 20140219573Abstract: Certain aspects relate to systems and techniques for compressing image data using pattern mode compression schemes. A pattern mode compression scheme can reduce the amount of data stored in a frame buffer to reduce power costs of an image display system. In some implementations, pattern mode compression can be suitable for compression of pixel blocks having a limited color palette with one or more pixels of a different foreground color, and a slope-enabled pattern compression can be suitable for compression of pixel blocks having a gradient. Input pixel values can be compared against a dynamically-populated, fixed size pattern entry database to determine whether pattern mode compression or slope-enabled pattern mode compression should be used to compress the image block.Type: ApplicationFiled: January 31, 2014Publication date: August 7, 2014Applicant: QUALCOMM IncorporatedInventors: Chia-Yuan Teng, Natan Haim Jacobson
