- Abstract:
- A segmentation method based on the wavelet analysis is proposed in this paper for segmenting visi-ble components from the bone marrow cell. Firstly,the wavelet transform is used to erase the effect of defocus-ing.Secondly,G component is chosen as clustering the information of characteristic parameters by using thethreshold multi-scale wavelet analysis,which is combined with saturation component according to different dis-tribution characteristic of leukocyte nucleus to construct a transpositional image named STG. The nucleus areextract by thresholding the image.Ultimately,it can provide an optimal initial clustering centers for K-meansclustering method to segment the red blood cells and the white blood cells from the background as well as sepa-rate them from each other. Through comparative analysis and algorithm testing,this method can effectively o-vercome the difficulties of complex components,poor discrimination and complicated defocusing during thecells segmentation ,the accuracy rate reaches 94.15 % .
