Systems and methods for digitized document image text contouring are provided. One or more memories may be coupled to one or more processors, the one or more memories including instructions operable to be executed by the one or more processors. The one or more processors may be configured to receive a digitized document image. The one or more processors may be configured to preprocess the digitized document image to generate a plurality of contours. The one or more processors may be configured to adjust a plurality of bounding boxes of the plurality of contours; analyze the adjusted plurality of bounding boxes; create one or more clips based on the analysis; dynamically threshold the one or more clips; perform optical character recognition of the one or more clips; and receive output responsive to the optical character recognition.

A method for digitized document image text contouring, comprising:
A system, comprising:
The system of 52, wherein the second pass includes canny edge detection to identify one or more shapes in the digitized document.
The system of 53, wherein the one or more shapes are smudged together to create one or more blobs of pixels.
The system of 53, wherein the canny edge detection yields one or more coordinate pairs to derive one or more geometric point arrays for creating the bounding box of the second contour.
The system of 52, wherein the processor is further configured to identify a minimum and maximum pixel area range that the first and second contours desirably fall within.
The system of 52, wherein the action of dynamically threshold the clip comprises altercating visibility of one or more pixels in the clip.
The system of 52, wherein the action of dynamically threshold the clip comprises applying a formula to determine a optimal threshold for achieving maximum optical character recognition (OCR) accuracy, in part, based on frequency of the most dark pixels in the clip.
The system of 52, wherein the output comprises textual output as a result of OCR.
The system of 52, wherein the action of combine the bounding box of the first contour and the bounding box of the second contour, comprises merging the bounding box of the first contour and the bounding box of the second contour to eliminate encapsulated boxes and overlaps.
A computer readable non-transitory medium comprising computer-executable instructions that, when executed by a digitized document image text contouring system, cause the digitized document image text contouring system to perform operations of:
The system of 52, wherein the process is configured to perform one or more conditional checks to validate one or more characters by transmitting the clip through one or more additional OCR engines.
