Embodiment 1
[0072] The establishment of embodiment 1 ant colony initial distribution
[0073] The initial distribution of the ant colony aims to give the initial distribution of the ant colony in the grayscale image, and its realization is initially through two approaches. For the subsequent cell position estimation module, it is jointly generated by the local gray variance technique and the cell dynamics. For the cell contour estimation module, it is only generated by the local gray variance technique.
[0074] (1) The initial ant colony is generated by the local gray variance technique:
[0075] 1) For any pixel (i, j) of the grayscale image, the intensity I (i,j) It is known that the gray variance of its local area (nearest 8 pixels) is defined as:
[0076] Δ σ ( i , j ) = 1 | N ...
Embodiment 2
[0085] Example 2 Multi-cell position estimation and tracking
[0086] The cell position estimation module aims to redistribute the ant colony initial distribution module (predicted initial ant colony + prior initial ant colony), that is, to form multiple ant colonies, and the corresponding position pheromone field is multimodal. Each ant colony The cluster estimates where a cell exists. Proceed as follows:
[0087] 1) Initialization: the amount of information is given at the position of any pixel (i, j) on the image and the initial diffusion input q ( i , j ) L ( 0 ) = 0 ;
[0088] 2) For the position of the ant at the pixel (i, j), select the next pixel according to the probability, namely P ( i ...
Embodiment 3
[0101] Example 3 Multi-cell position and contour joint tracking
[0102] The cell contour estimation module aims to use the prior initial ant colony distribution. Ants model through ant decision-making according to the local area gray variance. The obtained contour pheromone field is circular, and then estimates the contour of each cell. Proceed as follows:
[0103] 1) Initialization: the amount of information is given at the position of any pixel (i, j) on the image and the initial diffusion input q ( i , j ) C ( 0 ) = 0 ;
[0104] 2) For the position of the ant at the pixel (i, j), select the next pixel according to the probability, namely ( i ′ , j ′ ...
