Abstract: Disclosed is an improved OCR system wherein the same can be utilized for capturing and analyzing multiple images of a document to increase the efficiency and accuracy of digitizing printed texts on the document. Captured images are merged into a single set of character recognition results via a recognition method from multiple images, which include early fusion, late fusion, and hybrid fusion embodiments. The end product from each of the embodiments provides text and metadata that include recognized words. In late and hybrid fusion, words having confidence scores above a predetermined threshold are assembled together to form paragraphs to reconstruct a digital version of the document. In this way, the present invention utilizes multiple images that can be combined to aggregate information and achieve high accuracy when scanning and digitizing printed texts.

Abstract: An apparatus (1) and a method for the three dimensional inspection of saw marks (2) on at least one surface (3) of a wafer (4) are disclosed. At least one camera (6) is required to capture an image of the entire surface (3) of the wafer (4). At least one line projector (8) provides a light bundle (5), centered about a central beam axis (9). The line projector (8) is arranged such that the central beam axis (9) is at an acute angle (?) with regard to the plane (P) of the wafer (4).

Abstract: The invention relates to a method for identifying and extracting images of one or more users in an interactive environment comprising the steps of: —obtaining a depth map (7) of a scene in the form of an array of depth values, and an image (8) of said scene in the form of a corresponding array of pixel values, said depth map (7) and said image (8) being registered; applying a coordinate transformation to said depth map (7) and said image (8) for obtaining a corresponding array (15) containing the 3D positions in a real-world coordinates system and pixel values points; —grouping said points according to their relative positions, by using a clustering process (18) so that each group contains points that are in the same region of space and correspond to a user location (19); —defining individual volumes of interest (20) each corresponding to one of said user locations (19); —selecting, from said array (15) containing the 3D positions and pixel values, the points located in said volumes of interest for obtaining

Abstract: A user interface, and associated techniques, that permit a fast and efficient way of correcting speech recognition errors, or of diminishing their impact. The user may correct mistakes in a natural way, essentially by repeating the information that was incorrectly recognized previously. Such a mechanism closely approximates what human-to-human dialogue would be in similar circumstances. Such a system fully takes advantage of all the information provided by the user, and on its own estimates the quality of the recognition in order to determine the correct sequence of words in the fewest number of steps.

Abstract: In a speech recognition system, the combination of a log-linear model with a multitude of speech features is provided to recognize unknown speech utterances. The speech recognition system models the posterior probability of linguistic units relevant to speech recognition using a log-linear model. The posterior model captures the probability of the linguistic unit given the observed speech features and the parameters of the posterior model. The posterior model may be determined using the probability of the word sequence hypotheses given a multitude of speech features. Log-linear models are used with features derived from sparse or incomplete data. The speech features that are utilized may include asynchronous, overlapping, and statistically non-independent speech features. Not all features used in training need to appear in testing/recognition.

Abstract: A voice processing system is provided in which sets of engines running on a plurality of servers are configured differently from one another. The sets of engines may be configured to achieve different trade-offs between performance of a task and resources required to perform the task. In the voice processing system, a task routing server is provided that assigns different sets of sub-tasks to different sets of task engines. The number of engines used to perform a task and the number of engines in each set are adjusted. By adjusting the parameters settings for the set of engines based on the type of application, the particular requirements of the application, or the nature and importance of the subtasks, for example, advantages such as improvement of resource utilization and the hardware and software costs reduction may be obtained.
