abstract (eng):

We present a new method for segmentation of phase-contrast microscopic images of cells. The algorithm is based on the variational for-mulation of the level set method, i.e. minimizing of a functional, which describes the level set function. The functional is minimized by a gradi-ent ow described by an evolutionary partial dierential equation. The most signicant new ideas are initialization using thresholding and the introduction of a new term based on local variance that speeds up con-vergence and achieves more accurate results. The proposed algorithm is applied on real data and compared with another algorithm.
