摘要： Systems and methods for enhancing and comparing documents. An example method comprises: comparing document images to identify a first document image of a reference document that corresponds with a second document image of a related document; transforming the second document image based on a layout of the first document image; and performing character recognition of the second document image.

摘要： Disclosed are systems, methods and computer program products for using prior frame data for OCR processing of frames in video sources to detect natural language text therein. An example includes receiving a frame from a video source and retrieving prior frame data associated with the video source. The OCR-processing includes using prior frame data to detect blobs similar to blobs described in the prior frame data; using detected similar blobs to detect in the frame character candidates similar to character candidates described in the prior frame data; using detected similar character candidates to detect in the frame text candidates similar to text candidates described in the prior frame data; and using detected similar text candidates to detect in the frame text strings similar to text strings described in the prior frame data.
摘要翻译： 公开了用于使用先前帧数据进行视频源中的帧的OCR处理以检测其中的自然语言文本的系统，方法和计算机程序产品。 一个例子包括从视频源接收帧并检索与视频源相关联的先前帧数据。 OCR处理包括使用先前帧数据来检测类似于先前帧数据中描述的斑点的斑点; 使用检测到的类似斑点来检测与在先前帧数据中描述的字符候选相似的帧字符候选; 使用检测到的相似字符候选来检测与在先前帧数据中描述的文本候选相似的帧文本候选; 并且使用检测到的类似文本候选来检测与在先前帧数据中描述的文本串类似的帧文本串。
