The overlap score is used as the evaluation index of the accuracy of the precise
location. The overlap score is expressed as follows, and B r shows the precise location
result.

Experimental parameters: The number of the object-like box is set to 100, and the
local area D is set to 100 Â 100. Experimental platform: 3.60 GHz, Intel i7 CPU, 64-bit
win7 operating system, 8 GB of memory. Under this experimental condition, the
frames per second (fps) of the precise location method can reach 86 frames per second,
which meets the requirement of real-time performance.
