  • Publication number: 20240078377
    Abstract: A system and method for completing a character of a text of a digital document on a computing device, the computing device comprising a processor, a memory, and at least one non-transitory computer readable medium for recognizing input under control of the processor, the at least one non-transitory computer readable medium is configured to cause display (S900) of at least one typeset character of the text on a display interface of the computing device; detect a handwritten input stroke (S902) performed on the digital document in the vicinity of a typeset character; identify an first typeset character (S904) if the typeset character belongs to a list of base characters according to a language model; retrieve a predefined character version (S906) of the first typeset character from the memory; generate a hybrid character (S908) by replacing the initial typeset character by the predefined character; generate a list of character candidates (S910) with associated probabilities of recognition of the hybrid characte

  • Patent number: 11687618
    Abstract: The invention concerns a method comprising: detecting strokes of digital ink input on a computing device in a free handwriting format; detecting a text block from said strokes; performing text recognition on each text line of said text block, including extracting text lines from the text block and generating model data that associate each stroke of the text block with a character, a word and a text line of the text block; normalizing each text line from the free handwriting format into a structured format to comply with a document pattern. The normalization may comprise for each text line: computing a transform function to transform said text line into the structured format; applying the transform function to the text line; and updating the model data of said text line based on the transform function.

  • Patent number: 10852938
    Abstract: A system, method and computer program product for use in providing interactive ink from handwriting input to a computing device are provided. The computing device is connected to an input device in the form of an input surface. A user is able to provide input by applying pressure to or gesturing above the input surface using either his or her finger or an instrument such as a stylus or pen. The present system and method monitors the input strokes. The computing device further has a processor and an ink management system for recognizing the handwriting input under control of the processor.

  • Publication number: 20180095751
    Abstract: A method for managing a calculation task on a functionally asymmetric multicore processor, at least one core of the processor associated with one or more hardware extensions, comprises the steps of receiving a calculation task associated with instructions that can be executed by a hardware extension; receiving calibration data associated with the hardware extension; and determining an opportunity cost of execution of the calculation task as a function of the calibration data. Developments describe the determination of the calibration data in particular by counting or by computation (on line and/or off line) of the classes of the instructions executed, the execution of a predefined set of instructions representative of the execution room of the extension, the inclusion of energy and temperature aspects, the translation or the emulation of instructions or the placement of calculation tasks on the different cores. System and software aspects are described.
