Abstract

The invention provides a chromosome image processing method and a chromosome image processing system. The method comprises the following steps of: creating a copied image according to an original image of chromosomes; sequentially rotating the chromosomes in the copied image at a fixed angle interval in the same direction until the maximum rotation angle is more than or equal to 180 degrees, and recording the horizontal distance between the most remote two pixels in the horizontal direction after each time of rotation of the chromosomes in the copied image and a corresponding rotation frequency; calculating a corresponding rotation angle according to the corresponding rotation frequency when the horizontal distance between the most remote two pixels in the horizontal direction reaches theminimum value; and rotating the chromosomes in the original image to target positions according to the rotation angle and positions of centromeres of the chromosomes in the copied image. The chromosome image processing method and the chromosome image processing system have high speed of processing the chromosome image.

Description

technical field

[0001] The invention relates to a chromosome image processing method, and also relates to a chromosome image processing system. Background technique

[0002] Chromosomes of different species have their own specific morphological structure (including chromosome length, centromere position, arm ratio, satellite size, etc.) characteristics, and this morphological characteristic is relatively stable. Chromosomal karyotype analysis is to analyze the characteristics of chromosome length, centromere position, arm ratio, satellite size and other characteristics in organism cells. The analysis takes metaphase chromosomes of somatic cell division as the research object.

[0003] The automatic karyotype analysis of chromosomes based on image processing can improve the accuracy of analysis and judgment, and can store and process images conveniently. Combined with the standard chromosome model for comparative analysis. Usually, when performing comparative analysis of ch...
