Classification: CPC G  B | IPC B  G

Claim 15:
16. 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 through a plurality of processes 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, wherein assigning the score includes summing a plurality of scores generated by analyzing the sensor data through the plurality of processes, and wherein the plurality of processes include at least one of:
a maneuver analysis process, wherein an entered navigational route for the vehicle is utilized to identify a road surface in the operating environment,
a map analysis process including utilizing a location of the vehicle and three-dimensional map data to determine a geometry of the road surface in the operating environment,
an object identification process,
a salient feature process, or
a depth variance process operable to determine a relative position of a first identified object to a second identified 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

an autonomous navigation device receiving the path of travel output and controlling navigation of the vehicle based upon the path of travel output.
