中文说明：
本设计主要目的是实现染色体的识别计数。首先对图形进行预处理，将图像转化为灰度图、滤波去噪，然后对图像进行二值化，合理选取阈值，进行直方图阈值处理，最后去除图像中面积过小的杂点，最终实现识别计数。
English Description：
The main purpose of this design is to realize the recognition and counting of chromosomes. Firstly, preprocess the image, transform the image into grayscale image, filter and denoise, then binarize the image, reasonably select the threshold, carry out histogram threshold processing, and finally remove the small area of the clutter in the image, finally realize the recognition and counting.
