Abstract
Systems and methods for identifying screenshots within document images. An example method comprises: receiving an image of at least a part of a document; identifying, within the image, a polygonal object having a visually distinct border comprising a plurality of edges of one or more intersecting rectangles; asserting a screenshot image hypothesis with respect to the identified polygonal object; and responsive to evaluating at least one condition associated with one or more attributes of the identified polygonal object, classifying the identified polygonal object as a screenshot image.
Claims26
A method comprising:
- receiving an image of at least a part of a document;
- identifying, within the image, a polygonal object having a visually distinct border comprising a plurality of edges of one or more intersecting rectangles;
- and responsive to evaluating at least one condition associated with one or more attributes of the identified polygonal object, classifying the identified polygonal object as a screenshot image.
A computing device, comprising:
- a memory;
- a processor, coupled to the memory, the processor configured to:
- receive an image of at least a part of a document;
- identify, within the image, a polygonal object having a visually distinct border comprising a plurality of edges of one or more intersecting rectangles;
- responsive to evaluating at least one condition associated with one or more attributes of the identified polygonal object, classify the identified polygonal object as a screenshot image.
A computer-readable non-transitory storage medium comprising executable instructions that, when executed by a computing device, cause the computing device to perform operations comprising:
- receiving an image of at least a part of a document;
- identifying, within the image, a polygonal object having a visually distinct border comprising a plurality of edges of one or more intersecting rectangles;
- and
- responsive to evaluating at least one condition associated with one or more attributes of the identified polygonal object, classifying the identified polygonal object as a screenshot image.
