Nowadays manual observation by microscopes is the major method to detect leukemia cells. However this method takes much effort of doctors and depends much on the doctors' experience. This paper proposes a new method to locate the immature precursor cells based on distance transform and internal structures of cells. At first, Otsu method is used to binarize the image; secondly, the image is processed...
For the inevitable factors in the practical scene such as illumination chance and background interference, a new method is obtained to achieve the detection of human movement in this paper. This algorithm can remove most of the shadow and apply Gaussian filter to reduce interference. Then the moving targets under different conditions can be accurately tracked by combination of tracking algorithm and...
A new removing of the mixed Gaussian and salt-pepper noise algorithm is proposed based on median filtering and grey relational analysis. At first, a median pixel is determined in the filter window. Then the coefficient of the proposed method can be varied adaptively based on degree of the grey relational analysis. Finally, the values of the processed pixel can be calculated. The calculation results...
It is an effective means for the early diagnosis of leukemia to study immature precursor cells in marrow pathological images by computer image processing technology. This paper proposed a new method about localization of immature precursor cells in Pathological images of bone marrow. Firstly, we use modified OSTU method to binarize the image; then we process the image with morphological operations,...
This paper studies median filtering algorithm and several related fast algorithm proposed by other professors, then gives a novel fast algorithm of median filtering based on divide-and-conquer method and improved-choose-sort method. In new algorithm, all the pixels in filtering window are divided into several blocks, the median values of each block are computed using improved-choose-sort algorithm,...
