Abstract
The present disclosure provides methods, apparatuses and computer program products for hand-drawing shape-based document retrieval. An input hand-drawing shape may be obtained. A hand-drawing shape feature of the hand-drawing shape may be extracted through a feature extracting model. At least one target document may be retrieved by using the hand-drawing shape feature and a feature index library associated with a plurality of candidate documents, at least one document page in the target document locally matching the hand-drawing shape.
Claims15
A method for hand-drawing shape-based document retrieval, comprising:
- obtaining an input hand-drawing shape;
- extracting, through a feature extracting model, a hand-drawing shape feature of the hand-drawing shape;
- and
- retrieving at least one target document by using the hand-drawing shape feature and a feature index library associated with a plurality of candidate documents, at least one document page in the target document locally matching the hand-drawing shape.
An apparatus for hand-drawing shape-based document retrieval, comprising:
- at least one processor;
- and
- a memory storing computer-executable instructions that, when executed, cause the at least one processor to:
- obtain an input hand-drawing shape,
- extract, through a feature extracting model, a hand-drawing shape feature of the hand-drawing shape, and
- retrieve at least one target document by using the hand-drawing shape feature and a feature index library associated with a plurality of candidate documents, at least one document page in the target document locally matching the hand-drawing shape.
A computer program product for hand-drawing shape-based document retrieval, comprising a computer program that is executed by at least one processor for:
- obtaining an input hand-drawing shape;
- extracting, through a feature extracting model, a hand-drawing shape feature of the hand-drawing shape;
- and
- retrieving at least one target document by using the hand-drawing shape feature and a feature index library associated with a plurality of candidate documents, at least one document page in the target document locally matching the hand-drawing shape.
