Abstract: Disclosed are techniques for recognizing text from one or more frames of image data using contextual information. In some implementations, image data including a captured textual item is processed to identify an entity in the image data. A context can be selected using the entity, where the context corresponds to a dictionary. Text in the captured textual item can be identified using the dictionary. The identified text can be output to a display device.

Abstract translation: 公开了使用上下文信息从一个或多个图像数据帧识别文本的技术。 在一些实现中，处理包括捕获的文本项的图像数据以识别图像数据中的实体。 可以使用实体选择上下文，其中上下文对应于字典。 捕获的文本项目中的文本可以使用字典来识别。 识别的文本可以输出到显示设备。

Abstract: Disclosed are techniques for merging optical character recognized (OCR'd) text from frames of image data. In some implementations, a device sends frames of image data to a server, where each frame includes at least a portion of a captured textual item. The server performs optical character recognition (OCR) on the image data of each frame. When OCR'd text from respective frames is returned to the device from the server, the device can perform matching operations on the text, for instance, using bounding boxes and/or edit distance processing. The device can merge any identified matches of OCR'd text from different frames. The device can then display the merged text with any corrections.
