First Claim
Patent Images
1. A method for alignment of objects in a document comprising:
- for an input electronic document, identifying first and second objects to be aligned on a page of the document;
generating a one dimensional guideline profile for at least the first object based on a detection of saliency for the first object; and
aligning the first and second objects based on the guideline profile to form a modified document; and
outputting the modified document.

Abstract
An apparatus and automated method are disclosed for alignment of objects in a document which allows saliency within one or both objects to be a factor in the alignment. The method includes, for an input electronic document, identifying first and second objects to be aligned on a page of the document. A one dimensional guideline profile is generated for at least the first object based on a detection of saliency for the first object. The first and second objects are aligned based on the guideline profile to form a modified document and the modified document is output.

- 8. The method of claim 8, wherein when the pictorial object is categorized into the People category, the detection method includes detecting a location of at least one of a person'"'"'s face and a person'"'"'s eyes, the guideline profile having a peak value at a location corresponding to the person'"'"'s face or person'"'"'s eyes.

10. The method of claim 10, wherein the guideline profile is based on one dimensional averaging of saliency values in the map.
- 12. The method of claim 12, wherein the aligning includes convoluting the first and second guideline profiles to identify a peak and aligning the objects based on a location of the peak.

18. An apparatus for alignment of objects in a document comprising:
-
computer readable memory which stores an object alignment system comprising; an object detector for identifying first and second objects to be aligned within a document; a profile generator for generating a one dimensional guideline profile for at least the first object based on a detection of saliency for the first object; and an alignment generator for generating an alignment of the first and second objects based on the guideline profile; and a processor in communication with the memory which implements the object alignment system. - View Dependent Claims (19)

20. A computer implemented method for alignment of objects in a document comprising:
-
identifying objects to be aligned in an electronic document; assigning an object class to each of the objects selected from a plurality of object classes, the classes including at least one pictorial object class and a text object class; for each object to be aligned, selecting a respective saliency detection method based on the assigned object class; applying the selected detection method for each object to be aligned to generate a saliency representation; generating a one dimensional guideline profile for each object to be aligned based on the saliency representation; and aligning at least first and second of the objects based on the respective guideline profiles to form a modified document, including translating one of the first and second objects relative to the other of the first and second objects; and outputting the modified document.
