Optical character recognition (ocr) accuracy by combining results across video frames

An apparatus, comprising:

• a processor;
• and
• a memory having instructions which, when executed by the processor, performs an operation for evaluating text depicted in images of a source document, the operation comprising:
• receiving a stream of digital images depicting the source document;
• for a first digital one of the images:
• extracting text data in a portion of the document as depicted in the first image, and
• determining a first confidence level regarding an accuracy of the extracted text data;
• upon determining that the first confidence level satisfies a threshold value, saving the extracted text data as recognized content of the source document;
• and
• upon determining that the first confidence level does not satisfy the threshold value:
• extracting the text data from the portion of the document as depicted in one or more second images in the stream of digital images, and
• determining a second confidence level for the text data extracted from each second image until identifying one of the second images such that the second confidence level associated with the text data extracted from the identified second image satisfies the threshold value.
