20110267490 | CAMERA BASED METHOD FOR TEXT INPUT AND KEYWORD DETECTION - The present invention relates to a camera based method for text input and detection of a keyword or of a text-part within page or a screen comprising the steps of: directing a camera module on the printed page and capturing an image thereof; digital image filtering of the captured image; detection of word blocks contained in the image, each word block containing most likely a recognizable word; performing OCR within each word block; determination of A-blocks among the word blocks according to a keyword probability determination rule, wherein each of the A-blocks contains most likely the keyword; assignment of an attribute to each A-block; indication of the A-blocks in the display by a frame or the like for a further selection of the keyword; further selection of the A-block containing the keyword based on the displayed attribute of the keyword; forwarding the text content as text input to an application. | 11-03-2011 |
20120215540 | METHOD FOR CONVERTING CHARACTER TEXT MESSAGES TO AUDIO FILES WITH RESPECTIVE TITLES FOR THEIR SELECTION AND READING ALOUD WITH MOBILE DEVICES - The present invention relates to a method for selecting and downloading content from a content provider which is accessible via an IP/DNS/URL address to a mobile device, the content being any text information data, for converting the text information data to at least one audio message and for storing the at least one audio message as at least one audio file on the mobile device, wherein the at least one audio file is playable and discernable as a music file. Said method implemented on a mobile phone enables controlling and playing the audio messages as music files, for instance also in a car environment with a car kit enabling a control and a selection of one or more of said at least one audio files for playing from the mobile phone. | 08-23-2012 |

20110069067 | SYSTEMS AND METHODS FOR SELF-INTERSECTION AVOIDANCE IN RAY TRACING - Aspects include systems, methods, and media for implementing methods relating to detection of invalid intersections during ray tracing. Invalid intersections can arise from imprecision in computer-based number representation, causing ray origins to be located inappropriately. In some aspects, a ray can be associated with information relating to an expected angle between the ray's direction and a normal for a to-be-identified primitive intersected by that ray. If the angle between the ray's direction and the normal of an intersected primitive is within expectations, then that information can be used in predicting whether the intersection is valid. Such expectation information can be presented as a single bit determined by a shader performing a dot product of the ray and a normal of a primitive intersected by a parent ray, or can be obtained as a by-product of ray/primitive intersection testing. Such information also can be based on whether the shader is emitting to have reflection or refraction type ray behavior. | 03-24-2011 |
20140146049 | MEMORY EFFICIENT PROGRESSIVE REFINEMENT IN RAY TRACING - In one aspect, a method provides for iteratively taking passes of samples for each pixel of a set of pixels. Initially, the set of pixels can be all of the pixels of an image. For each pixel, an accumulated color at the beginning of a pass and at the end of a pass can be compared. If a difference between these is within a threshold, a convergence count, which begins at an initial value, is reduced. If the difference is not within the threshold, then the convergence count is reset. When the convergence count reaches a preset value, then the pixel is considered converged and removed from the set. However, if a pixel adjacent to a converged pixel fails a convergence test, then the converged pixel is reset to unconverged and returned to the set and at least a minimum number of additional sample passes are undertaken for that pixel. | 05-29-2014 |

20110267347 | SYSTEMS AND METHODS FOR PRIMITIVE INTERSECTION IN RAY TRACING - Aspects include systems, methods, and media for implementing methods relating to increasing consistency of results during intersection testing. In an example, vertexes define edges of primitives composing a scene (e.g., triangles defining a mesh for a surface of an object in a 3-D scene). An edge can be shared between two primitives. Intersection testing algorithms can use tests involving edges to determine whether or not the ray intersects a primitive defined by those edges. In one approach, a precedence among the vertexes defining a particular edge is enforced for such intersection testing. The precedence causes an intersection tester to always test a given edge in the same orientation, regardless of which primitive defined (at least in part) by that edge is being intersection tested. | 11-03-2011 |
