1. A system for an attention-based perception in a vehicle, comprising:
a camera device configured to provide an image of an operating environment of the vehicle;
a computerized perception device, operable to:
monitor the image from the camera device;
analyze sensor data to identify at least one feature in the image as corresponding to an object in the operating environment of the vehicle and assign a score for the at least one feature based upon one of an identification of the object, a location of the object or a behavior of the object;
define a plurality of candidate regions of interest upon the image, wherein each of the plurality of candidate regions of interest includes a portion of the image;
for each of the plurality of candidate regions of interest, correlate the score for the at least one feature to the plurality of candidate regions of interest to accrue a total region score;
select a portion of the plurality of candidate regions of interest for analysis based upon the total region score for each of the plurality of candidate regions of interest; and
analyze the portion of the plurality of candidate regions of interest to generate a path of travel output; and
a vehicle control device receiving the path of travel output and controlling the vehicle based upon the path of travel output.
