Here is a histogram method. EMD algorithm is different from our well-known target detection algorithm, here the full name of EMD is the Earth Mover, s Distance, land mobile distance is a measure of the guidelines. Lighting changes can cause the color histogram of the drift, caused by position changes of color values , this time some of the histogram matching strategy failure. EMD algorithm itself is a generic algorithm, it is actually measured is how to tell a histogram shape into another histogram shape, including part of the histogram (or all) to a new location in the histogram on any dimensions of the histogram of this measure.
Related to the specific content of the EMD land mobile distance: the Learning openCV land mobile distance, or refer to the back of the accompanying papers.
Another, this approach is not to improve the particle filter algorithm to be further explored.
