Abstract: Embodiments disclosed pertain to Optical Character Recognition using Multiple Hypothesis Testing based techniques on images occurring in a variety of settings, including images captured by mobile stations. In some embodiments, a set of bifurcation points for a character cluster in an image may be determined. The character cluster may comprise non-uniformly spaced text or closely spaced text. A plurality of hypotheses may be determined for the character cluster, where each hypothesis is based on a subset of the bifurcation points and comprises a set of words generated from the character cluster. A plurality of scores corresponding to the plurality of hypotheses may be determined, where each score corresponds to a hypothesis, and a hypothesis may be selected from among the plurality of hypotheses based on a score associated with the selected hypothesis.
Abstract translation: 所公开的实施例涉及使用基于多种假设检验技术的光学字符识别，所述技术包括在各种设置中出现的图像，包括由移动台捕获的图像。 在一些实施例中，可以确定图像中的字符簇的一组分叉点。 字符簇可以包括非均匀间隔的文本或紧密间隔的文本。 可以针对字符簇确定多个假设，其中每个假设基于分支点的子集，并且包括从字符簇生成的一组单词。 可以确定与多个假设相对应的多个分数，其中每个分数对应于假设，并且可以基于与所选择的假设相关联的评分从多个假设中选择假设。

Abstract: An electronic device and method capture multiple images of a scene of real world at a several zoom levels, the scene of real world containing text of one or more sizes. Then the electronic device and method extract from each of the multiple images, one or more text regions, followed by analyzing an attribute that is relevant to OCR in one or more versions of a first text region as extracted from one or more of the multiple images. When an attribute has a value that meets a limit of optical character recognition (OCR) in a version of the first text region, the version of the first text region is provided as input to OCR.
