Abstract
An apparatus and method are disclosed for context dependent cropping of a source image. The method includes identifying a context for the source image, identifying a visual class corresponding to the identified context from a set of visual classes, applying a class model to the source image to identify a candidate region of the image based on its relevance to the visual class, and identifying a subpart of the source image for cropping, based on the location of the candidate region.
Claims26
A method for cropping a source image comprising:
- identifying a context for the source image;
- identifying a visual class corresponding to the identified context from a set of visual classes;
- with a processor, applying a class model to the source image to identify a candidate region of the image based on its relevance to the visual class;
- and
- identifying a subpart of the source image for cropping based on the candidate region.
An apparatus for cropping a source image comprising:
- a context finder which automatically identifies a context for the source image;
- a visual categorizer which automatically identifies a visual class corresponding to the identified context from a set of visual classes;
- and applies a class model to the source image to identify a candidate region of the image based on its relevance to the visual class;
- an image cropper which crops a subpart of the source image based on the candidate region;
- a processor which implements the context finder visual categorizer and image cropper;
- and
- memory which stores the source image to be cropped.
A computer implemented method of variable printing comprising:
- identifying a context for a document to receive a cropped image;
- identifying a visual class corresponding to the identified context from a set of visual classes;
- applying a class model to a source image to identify a candidate region of the image based on its relevance to the visual class;
- cropping a subpart of the source image based on the candidate region;
- and
- incorporating the cropped subpart into the document.
A method for assisting a user in assessing the relevance of documents responsive to a query comprising:
- receiving a user query;
- retrieving a document responsive to the query;
- identifying a context based on at least one of the user query and the retrieved document;
- identifying a visual class corresponding to the identified context from a set of visual classes;
- with a processor, applying a class model to a source image in the retrieved document to identify a candidate region of the source image based on its relevance to the visual class;
- identifying a subpart of the source image for cropping based on the candidate region;
- and
- displaying a context-dependent thumbnail derived from the identified subpart to assist a user in assessing the relevance of the document.
A computer program product comprising a non-transitory medium on which a control program is recorded which when executed by a computer apparatus, performs a method for cropping a source image comprising:
- identifying a context for the source image;
- identifying a visual class corresponding to the identified context from a set of visual classes;
- applying a class model to the source image to identify a candidate region of the image based on its relevance to the visual class;
- and
- identifying a subpart of the source image for cropping based on the candidate region.
