Abstract: Methods systems and articles of manufacture for recognizing and locating one or more objects in a scene are disclosed. An image and/or video of the scene are captured. Using audio recorded at the scene an object search of the captured scene is narrowed down. For example the direction of arrival (DOA) of a sound can be determined and used to limit the search area in a captured image/video. In another example keypoint signatures may be selected based on types of sounds identified in the recorded audio. A keypoint signature corresponds to a particular object that the system is configured to recognize. Objects in the scene may then be recognized using a shift invariant feature transform (SIFT) analysis comparing keypoints identified in the captured scene to the selected keypoint signatures.

Abstract: An example image capture device determines a region of interest using a first image captured while a light source is powered off and a second image captured while a light source is powered on and uses the region of interest to automatically set configurations. In one example an image capture device includes a controlled light source an image sensor configured to capture images and a processing unit configured to cause the image sensor to capture a first image of a scene while the controlled light source is powered off cause the image sensor to capture a second image of the scene while the controlled light source is powered on calculate luminance differences between a plurality of regions in the first image and a plurality of collocated regions in the second image and determine that a region of interest includes those regions for which the luminance differences exceed a threshold.
