[0050] figure 1 It is a structural diagram of the present invention. Such as figure 1 Shown for figure 2 with image 3 For each frame of the original image sequence of the original cell (T cell) image sequence, first use the weight and cell probability density of the cell set in the previous frame and the newly discovered cell set in the current frame to obtain the predicted cell set in the current frame and the cell prediction in the cell set Probability density and cell set weight, and then update the posterior probability density and cell set weight of the cells in the cell set through the similarity calculation, and finally the cell tracking output can be completed without correlation. The specific steps are:
[0051] 1) Initialization of the cell set: Before cell tracking is performed on each frame of image, according to prior knowledge, the image is divided into blocks in the area where cells may appear in the image, and the existence probability of new cells is initialize...
