  • Digital-image shape recognition using tangents and change in tangents
    Patent number: 11256948
    Abstract: In one aspect, a method of optical character recognition of digital character objects in digital images includes the step of obtaining a digital image. The digital images include rendering of a first object in the digital image. The first object comprises a set of sub-objects and a set of relationships between the sub-object. The method includes the step of generating a definition of a first object by defining an object outline for the first object as a set of sub-objects; defining a sub-object outline for each sub-object as a set of lines and curves; and defining each relationship between each set of connected sub-objects in terms of one or more intersections or one or more corners.
