Abstract: The present invention provides a method for performing positioning operations, wherein the method includes the steps of: receiving first positioning information from a first source; receiving second positioning information from a second source; obtaining surrounding environment information of a vehicle from a sensor; and referring to the surrounding environment information to determine a positioning strategy to use at least one of the first positioning information and the second positioning information to obtain a location of the vehicle.

Abstract: A human image detection and tracking systems and methods are disclosed. A human image detection method comprises receiving a depth image data from a depth image sensor by an image processing unit, removing a background image of the depth image sensor and outputting a foreground image by the image processing unit, receiving the foreground image and operating a graph-based segment on the foreground image to obtain a plurality of graph blocks by a human image detection unit, determining whether a potential human region exists in the graph blocks, determining whether the potential human region is a potential human head region, determining whether the potential human head region is a real human head region, and regarding the position of the real human head region is the human image position by the human image detection unit if the potential human head region is the real human head region.
