摘要： Systems and methods for performing OCR of a series of images depicting text symbols. An example method comprises performing OCR a series of images to produce symbol sequences and corresponding symbol sequence quadrangles; identifying median string; calculating transformation of the symbol sequence quadrangles into a common coordinate system; determining distances between the transformed symbol sequence quadrangles; identifying a median symbol sequence quadrangle; displaying, using the median symbol sequence quadrangle, a resulting OCR text representing at least a portion of the original document.

摘要： A method of verifying optical character recognition (OCR) results may involve: performing OCR on one or more initial images of a document and displaying initial OCR results of the document to a user; receiving a feedback from the user regarding an error location in the initial OCR results, the error location being a location of a misspelled character sequence; receiving an additional image of the document, which corresponds to the error location, and performing OCR of the additional image to produce additional OCR results; identifying a cluster of character sequences, which correspond to the error location, using the initial OCR results and the additional OCR results; identifying an order of character sequences in the cluster of character sequences based on their respective probability values; and displaying to the user modified optical character recognition results, which contain in the error location a corrected character sequence, but otherwise are identical to the initial optical character recognition results, wherein the corrected character sequence is a character sequence, which has the highest probability value among the character sequences of the cluster, while being different from the misspelled character sequence.

摘要： The subject matter of this specification can be implemented in, among other things, a method that includes receiving a first image from a first camera depicting a first view of a physical item, where the physical item displays a plurality of characters. The method includes receiving a second image from a second camera depicting a second view of the physical item. The method includes performing optical character recognition on the first image to identify first characters and a first layout in the first image and on the second image to identify second characters and a second layout in the second image. The method includes combining the first characters with the second characters by comparing the first characters with the second characters and the first layout with the second layout. The method includes storing the combined first and second characters.

摘要： The present disclosures provide methods of optical character recognition for a patterned document having one static element and one information field. Systems and methods are disclosed to identify in each of a current and a previous image of a series of images of an original document overlapping with each other, a corresponding plurality of base points, wherein each base point is associated with one textural artifact in each of the current image and the previous image using an OCR text of the current image; identify parameters of a coordinate transformation converting coordinates of the previous image into coordinates of the current image; associate a part of the OCR text with a cluster of a plurality of clusters of symbol sequences; identify a median string representing the cluster of symbol sequences; and produce a resulting OCR text representing at least a portion of the original document.

摘要： Systems and methods for performing OCR of a series of images depicting text symbols. An example method comprises: receiving, by a processing device, a current image of a series of images of an original document, wherein the current image at least partially overlaps with a previous image of the series of images; performing optical symbol recognition (OCR) of the current image to produce an OCR text and a corresponding text layout; associating, using a coordinate transformation, at least part of the OCR text with a first cluster of a plurality of clusters of symbol sequences, wherein the OCR text is produced by processing the current image and wherein the symbol sequences are produced by processing one or more previously received images of the series of images; identifying a first median string representing the first cluster of symbol sequences based on a first subset of images of the series of images; identifying a first template field of a document template corresponding to the first cluster based on the first median string representing the first cluster and the text layout of the current image; analyzing the symbol sequences from the first cluster to identify suitable symbol sequences, wherein the suitable symbol sequences satisfy first parameters of the first template field; identifying, for the first cluster, a second-level median string representing the cluster of symbol sequences based on a plurality of the suitable symbol sequences; producing, using the second-level median string, a resulting OCR text representing at least a portion of the first template field of the original document.
