Abstract
Methods, and corresponding systems, of generating one or more image anchor templates for discriminating between documents of a first class and documents of other classes are provided. The methods include generating one or more candidate image anchor templates; determining, using a computer processor, a quality score for each of the one or more candidate image anchor templates; ranking the one or more candidate image anchor templates according to the quality scores of the one or more candidate image anchor templates; and selecting one or more of the most highly ranked image anchor templates.
Claims20
A method of generating one or more image anchor templates for discriminating between documents of a first class and documents of other classes, said method comprising:
- a) generating one or more candidate image anchor templates using one or more seed image anchor templates and/or at least one of one or more exemplars of the first class;
- b) determining a quality score for each of the one or more candidate image anchor templates using a computer processor and the one or more exemplars of the first class;
- c) ranking the one or more candidate image anchor templates according to quality score;
- and
- d) selecting one or more of the most highly ranked image anchor templates.
A system for generating one or more image anchor templates for discriminating between documents of a first class and documents of other classes, said system comprising:
- a generator module that generates one or more candidate image anchor templates using one or more seed image anchor templates and/or at least one of one or more exemplars of the first class;
- a template scoring module that determines a quality score for each of the one or more candidate image anchor templates using a computer processor and the one or more exemplars of the first class;
- a ranking module that ranks the one or more candidate image anchor emplates according to quality;
- a selection module that selects one or more of the most highly ranked image anchor templates.
A method for determining whether a document is a member of a first class or a member of other classes, said method comprising:
- a) generating one or more candidate image anchor templates using one or more seed image anchor templates and/or at least one of one or more exemplars of the first class;
- b) determining a quality score for each of the one or more candidate image anchor templates using a computer processor and the one or more exemplars of the first class;
- c) ranking the one or more candidate image anchor templates according to quality score;
- d) selecting one or more of the most highly ranked image anchor templates;
- and
- e) determining whether the one or more of the most highly ranked image anchor templates identify the document as a member of the first class.
