Embodiment Construction

[0027] The invention proposes a multi-cell automatic tracking method based on the firework algorithm, which searches and finds cells in image sequences through sparks generated by firework explosions. For each frame of image, the system first obtains the initial state of potential cells through fireworks initialization, and then searches and matches in the image according to an appropriate fitness function and fireworks search strategy to obtain real cells. For the tracking results, if it cannot be associated with an existing cell, it is considered that a new cell has been found; if several consecutive searches are all clutter, it is considered that all cells in the current frame have been tracked.

[0028] figure 1 It is the structure diagram of this system. Such as figure 1 shown, for figure 2 and image 3 For each frame of the original image of the original cell (T cell) image sequence, the position of the fireworks (cells) is initialized in the image area first, and t...

Abstract

The invention provides a multi-cell automatic tracking system based on the fireworks algorithm, which generates potential cells in the image sequence by sparks generated by the fireworks explosion, and then searches and matches the real cells in the image according to the appropriate fitness function and the fireworks search mechanism, Finally, the nearest neighbor association is used to complete the cell tracking. The firework algorithm tracking system provided by the present invention can accurately track multiple cells. For multiple unknown and changing cells, cells with different dynamic characteristics, and neighboring cells, it can achieve accurate tracking effects, high tracking stability, and low false alarm rate. , The missed detection rate is low.

Description

technical field [0001] The invention provides a multi-cell tracking system based on fireworks algorithm, which belongs to the field of cell tracking. Background technique [0002] Cells are the basic structural and functional units of organisms, and the activities of cells reflect the entire biological process of organic life. Therefore, the research on cell behavior analysis has long been the focus of the medical field, such as virus prevention, drug development , genetic research, etc. The traditional analysis method of cell movement is to use advanced medical instruments to conduct manual observation by professionals. When dealing with a large number of scattered cell images, only using the naked eye for long-term tracking observation is not only boring and laborious, but also easy to cause confusion. With the rapid development of statistics, image processing and computer vision technology, many automatic cell tracking technologies have emerged. Compared with manual cell...
