Object-tracking apparatus and method in environment of multiple non-overlapping cameras

摘要

Disclosed herein is an object-tracking apparatus and method in the environment of multiple non-overlapping cameras. Color rendering values are divided into a plurality of sub-color regions. RGB pixels of objects in a first image and a second image are converted into first hue values and second hue values, respectively. The first hue values are assigned to corresponding sub-color regions, and then a first color histogram is generated. The second hue values are assigned to corresponding sub-color regions, and then a second color histogram is generated. An area of the first color histogram is extended. It is determined whether the second color histogram is included in the extended area of the first color histogram. It is determined that the object in the first image is identical to the object in the second image if the second color histogram is included in the extended area of the first color histogram.
