Description: RNA 和 DNA序列模拟 基因建模 数值模拟 采用matlab 编写 能计算几千个 基因点的特性和行为-In one type of gene expression analysis, fluorescently tagged messenger RNA from different cells are hybridized to a microscopic array of thousands of complimentary DNA spots that correspond to different genes. Illuminated spots emit different color light, indicating which genes are expressed (e.g., green=control, red=sample, yellow=both).
In this case study, MATLAB, the Image Processing and Signal Processing toolboxes were used to determine the green intensities from a small portion of a microarray image containing 4,800 spots. A 10x10 pattern of spots was detected by averaging rows and columns to produce horizontal and vertical profiles. Periodicity was determined automatically by autocorrelation and used to form an optimal length filter for morphological background removal. A rectangular grid of bounding boxes was defined. Each spot was individually addressed and segmented by thresholding to form a mask. The mask was used to isolate each spot from surrounding background. Individu Platform: |

理，采用连通图计数和面积计数法进行鱼卵的计数，精确性在95 以上。该方法减轻了操作者劳动强度，弥补了
人视觉的不足之处，可以有效地提高工作效率和计数精度，并且可避免鱼卵损伤，有利于后续工作的开展，具有一

low efficiency and eggs damage． In order to cover the shortcomings，being helpful for follow-up work，two methods
of counting fish spawns based on image processing was proposed in this paper． Through the powerful image processing
function of Matlab software，putting up median filter，gray processing，binary processing and morphological operation
to the reading image dealt by Photoshop software． Then on the theory of connected graph counting and area
comparison，counting up the number of spawns，the degree of counting precision is higher than 95 which have
certain theoretical and practical value． Platform: |
