Problems solved by technology

For the case of cell division, there are probabilistic model methods, spatial topology nearest neighbor methods, etc. These methods rely on prior information and design special models, making it difficult for these methods to be applied to other cell data

Abstract

The invention discloses a multi-cell tracking method of a two-layer multi-bernoulli random finite ant colony, comprising a multi-bernoulli random finite reconnaissance ant colony based on ant colony division of labor and a multi-bernoulli random finite foraging ant colony. Dobernoulli stochastic finite reconnaissance ant colony is generated by modeling the behavior of reconnaissance ant colony from chaos to certainty and defining the information exchange between reconnaissance ant and its neighbors. When the reconnaissance ant colony completes the task, the generated Dobernoulli stochastic finite foraging ant colony is transformed into Dobernoulli stochastic finite foraging ant colony, and the final pheromone field is generated by modeling foraging decision behavior and updating pheromonecontinuously. The pheromone field generated by random finite foraging ant colony and the current ant state are obtained. The existence probability and probability distribution of the corresponding Dobernoulli random finite foraging ant colony are obtained. The state of the corresponding cell and the lineage tree of the cell are further obtained.

Description

technical field [0001] The invention belongs to the field of cell tracking, and more specifically relates to a double-layer multi-Bernoulli stochastic finite ant colony multi-cell tracking method. Background technique [0002] The quantitative analysis of cell behavior needs to be reliable before it is still the main method in the laboratory. It has the following disadvantages, such as: time-consuming, difficult to replicate results, and difficult to track in parallel. Therefore, automatic tracking technology is the main research of cell tracking in recent years. hotspot. [0003] At present, there are many methods for multi-cell automatic tracking, and the nearest neighbor method is the most effective for tracking in sparse situations. Under the Bayesian framework, such as Kalman filter, multiple hypothesis tracking method, particle filter, stochastic finite set method are applied to multi-cell tracking. For most tracking methods, if the segmentation detection accuracy is...
