1. A system for identifying regions of interest in visual imagery, the system comprising:
a processor; a memory, the memory including executable instructions encoded thereon that, when executed by the processor, causes the processor to perform operations of:
receiving a series of consecutive frames representing a scene as captured from N sensors, the frames having at least a current frame and a previous frame;generating a surprise map based on features found in the current frame and the previous frame, the surprise map having a plurality of values corresponding to spatial locations within the scene; anddetermining a surprise in the scene based on a value in the surprise map exceeding a predetermined thresholdwherein the processor uses a number B, less than N, of the N sensors to capture the series of consecutive frames, such that the B sensors are active during a burst period and are deactivated during a wait period during which at least one of the remaining sensors is active, andwherein the processor determines, for the B sensors, whether to store over the wait period at least one of a prior map and the previous frame. |
