This paper proposes a new recognition algorithm based on fractal dimension and image center of gravity after the segmentation of marrow cell images in the clinical haematology and cytology atlas which can be used to extract. The fractal feature of every marrow cell image. Since the texture of a color image contains not only certain statistical similarity but also the color distributions

a new color parameter is extracted from the color images of marrow cells and discussed with parameter S of HIS for the fractal dimension. The experimental result shows that different marrow cell image has the certain discrimination in fractal dimension and some images can be recognized for classification.
