Mobile device image acquisition using objects of interest recognition

摘要

An approach is provided for acquiring images with camera-enabled mobile devices using objects of interest recognition. A mobile device is configured to acquire an image represented by image data and process the image data to identify a plurality of candidate objects of interest in the image. The plurality of candidate objects of interest may be identified based upon a plurality of low level features or “cues” in the image data. Example cues include, without limitation, color contrast, edge density and superpixel straddling. A particular candidate object of interest is selected from the plurality of candidate objects of interest and a graphical symbol is displayed on a screen of the mobile device to identify the particular candidate object of interest. The particular candidate object of interest may be located anywhere on the image. Passive auto focusing is performed at the location of the particular candidate object of interest.

主权项

1. A mobile device comprising:
one or more processors; one or more memories communicatively coupled to the one or more processors; a camera; a display for displaying images to a user and for receiving user input from the user; and a photo application executing on the mobile device and being configured to:
cause the camera to acquire an image represented by image data,process the image data to identify a plurality of candidate objects of interest in the image by:
identifying a plurality of prominent regions within the image,assigning a plurality of bounding boxes to the plurality of prominent regions within the image, andfor each bounding box from the plurality of bounding boxes, determining one or more of a color contrast score, an edge density score, or a superpixel straddling score,select a particular candidate object of interest from the plurality of candidate objects of interest based upon the scores for the plurality of bounding boxes, wherein the particular candidate object of interest has a location other than the center of the display, andcause passive auto focusing to be performed at the location other than the center of the display of the particular candidate object of interest.
