Systems and methods for facilitating tracking a target in an imaged scene

In systems and methods disclosed herein, a transform may be determined for a given target object and background in an image between a native color space of the image and a second multi-dimensional color space representing a preferred color space for a tracker. The transform may then be applied to convert a plurality of pixels in the imaged scene to the second multi-dimensional color space thereby advantageously increasing a perceived contrast by the tracker between the target object and the background.. ...
