Table data recovering in case of image distortion

A non-transitory computer-readable medium having instructions stored thereon that, when executed by at least one processing device, cause the processing device to:

• identify edges of at least a section of a document in a source image, wherein the document comprises at least one first row of text;
• identify a plurality of characters in the document;
• identify ones of the characters as a plurality of word portions;
• generate a plurality of first polynomials that approximate points of the characters within the word portions;
• generate a second polynomial that approximates the points of the characters of at least a first word portion and a second word portion among the word portions and corresponds to the first row of text;
• identify at least one stretching coefficient of the first row of text based on a maximum length of the section between the edges and a length of the second polynomial;
• and
• map, by the processing device, portions of the source image along the first row of text to new positions in a corrected image based on the second polynomial and the stretching coefficient.

A system comprising:

• at least one memory that stores instructions;
• and
• at least one processing device to execute the instructions to:
• identify edges of at least a section of a document in a source image, wherein the document comprises at least one first row of text;
• identify a plurality of characters in the document;
• identify ones of the characters as a plurality of word portions;
• generate a plurality of first polynomials that approximate points of the characters within the word portions;
• generate a second polynomial that approximates the points of the characters of at least a first word portion and a second word portion among the word portions and corresponds to the first row of text;
• identify at least one stretching coefficient of the first row of text based on a maximum length of the section between the edges and a length of the second polynomial;
• and
• map portions of the source image along the first row of text to new positions in a corrected image based on the second polynomial and the stretching coefficient.
