1. A method for tracking a biological cell in an image sequence, the image sequence including at least, a first image and a second image taken during development of biological cells in which biological cells are movable and dividable, the method comprising the steps of:

  • identifying, using one or more processors, a plurality of biological cells in the first image and a plurality of biological cells in the second image;

    determining, using the one or more processors, a matching probability of a biological cell in the second image with a biological cell in the first image, based on relative positional relationships between the plurality of biological cells in the first image and relative positional relationships between the plurality of biological cells in the second image; and

    determining, using the one or more processors and based on the determined matching probability, a matching result indicating whether the biological cell in the second image matches with the biological cell in the first image, wherein a match indicates that the biological cell in the second image corresponds with or originates from the corresponding biological cell in the first image; and

    displaying, at an output device operable connected with the one or more processors, the matching result.
