DDC_design

there are two parts in these codes. the first implements an eight point algorithm which is used to compute the fundamental matrix in computer vision. the second is used to compute the optical flow and the unreliable region.

Intermodulation or intermodulation distortion (IMD) is the amplitude modulation of signals containing two or more different frequencies in a system with nonlinearities. The intermodulation between each frequency component will form additional signals at frequencies that are not just at harmonic frequencies (integer multiples) of either, but also at the sum and difference frequencies of the original frequencies and at multiples of those sum and difference frequencies.

这个函数用于多目标跟踪数据关联，结合了最近邻数据关联个CJPDA数据关联算法，每个目标分配最多一个量测(This function is used for multi-target tracking data association, combined with nearest neighbor data association a CJPDA data association algorithm, each target allocation up to a measurement)
