Embodiment 1
[0046] Example 1 Tracking of Existing Cells
[0047] Such as image 3 As shown in (a), there are 4 cells in the previous frame. In the current frame, these cells need to be tracked sequentially according to the cell saliency index. First, use the PSO-based tracking module. The steps are:
[0048] 1) Initialization of particle swarm: It is known that there are M cells in frame t-1 in Indicates cell K t-1 (k) the state (centroid and contour) in frame t-1, for the cell K in which the saliency index (discussed in the contour module) is largest t-1 (k), initialize a population size to N T particle swarm Particle state is x i , K t - 1 ( k ) t = [ x i ...
Embodiment 2
[0065] Example 2 Tracking of Emerging Cells
[0066] For the tracking of emerging cells in the current frame, it is realized by the PSO-based discovery module and the PSO-based contour module. The steps of the PSO-based discovery module are:
[0067] 1) Initialization of particle swarm: initialize a population size N in the t-th frame image D particle swarm Particle state is The particles are randomly distributed in the image Y t In , the initial velocity of the particles is random and distributed in j=1,...,4, the initial distribution of the particle swarm is as follows Figure 4 (a) shown.
[0068] 2) The fitness function of the PSO-based discovery module: f D ( x i D , n ) = ϵ ifA ...
