AI Technical Summary

Problems solved by technology

However, a suitable segmentation definition is very difficult and time-consuming; on the other hand, to train a classifier with strong generalization ability, a large number of training samples are required, which is very challenging for the scarce data

Embodiment Construction

[0051] The technical scheme of the present invention will be described in detail in conjunction with the accompanying drawings:

[0052] The cell mitosis detection method disclosed by the present invention, such as figure 2 shown, including the following steps:

[0053] Step 1. The pictures used in the present invention are scanned by a 10-band multispectral microscope, and each spectral band is a visible spectrum. In addition, for each spectral band, we digitized pictures with 17 different focal planes, any two adjacent planes differing by 500 nm. For each picture in each band, it is represented by a column vector, and the length of the column vector is the same as the size of the original picture matrix.

[0054] The original image is described in the form of a matrix, and each column of the matrix is ​​used as a unit to expand into a large column vector. The length of the vector is the same as the size of the original matrix.

[0055] Step 2, use the vector generated in...

Abstract

The invention discloses a cell mitosis detection method which comprises the following steps that image matrix vectorization is carried out; a new matrix is established; matrix low-rank decomposing is carried out; a new matrix is established for each column of a sparse matrix; matrix summation is carried out; low-rank decomposing process iteration is carried out; and matrix AND operation is carried out. According to the cell mitosis detection method, mitosis cells are regarded as a sparse part in low-rank representation, non-mitosis parts are regarded as a low-rank part, compared with an existing detection method based on mode recognition, a large amount of pre-training is of no need, detecting results can be obtained quickly, and under the same experiment condition, higher F-measure and Recall values can be obtained.

Description

technical field [0001] The invention discloses a cell mitosis detection method and relates to the technical field of image information processing. Background technique [0002] According to the 2009 breast cancer incidence data released by the National Cancer Center and the Ministry of Health's Bureau of Disease Control and Prevention, the incidence of breast cancer in the national tumor registration area ranks first among female malignant tumors, and the incidence of breast cancer in Chinese women is gradually increasing. It has increased from 0.017% five years ago to 0.052% last year, an increase of more than three times. According to the "2012 China Cancer Annual Report", the current incidence of tumors in my country is 285.91 / 100,000, and an average of 6 people are diagnosed with malignant tumors every minute every day. Breast cancer ranks sixth in the incidence of malignant tumors in the country. The incidence rate is increasing year by year, and the age of onset tends ...
