基于機器視覺的寄生蟲卵顯微圖像自動識別研究
[Abstract]:With the development of computer technology and the wide application of interdiscipline in various fields, the automatic recognition technology of microscopic image based on machine vision has been developed rapidly in the field of medicine, which not only provides a reliable and efficient tool for clinical diagnosis. At the same time, it also brings convenience to medical research and teaching. The detection of parasite eggs is one of the most important items in medicine. The traditional examination of parasite eggs is mostly by artificial microscope, which is not only low efficiency and high working intensity, but also can not preserve the complete case data due to the subjective influence of the operators. It is unfavorable to clinical dynamic observation. The automatic detection based on machine vision is not only efficient and pollution-free, but also adapt to the needs of modern medical information development. Therefore, this paper is based on the research of microscopic image recognition of parasite eggs and cells. The process of parasite egg microscopic image acquisition and recognition based on machine vision is studied. The specific research contents are as follows: 1. This paper mainly introduces the hardware structure design of the parasite egg microscopic image recognition system based on machine vision, including the automatic collection device of egg specimen, the automatic shooting device of microscope, the illumination system, the CCD camera, the image acquisition card and so on. In view of the high noise characteristics of parasite egg microscopic image, the image preprocessing and segmentation methods are studied, and an improved two-dimensional maximum entropy threshold genetic algorithm combined with morphological image segmentation optimization algorithm is proposed. Can accurately and quickly realize the parasite egg microscopic image denoising segmentation. 3. In this paper, several common characteristic types of parasite egg microscopic image are introduced in detail, and the methods of extracting all kinds of characteristics are studied. To find out a group of best feature combinations as the input amount of parasite egg microscopic image to characterize the characteristics of various typical parasite egg microscopic images. 4. This paper studies several intelligent recognition algorithms, such as BP (Back Propagation) neural network, SVM (Support Vector Machine), which designs classifiers based on BP neural network and SVM classifier, respectively, according to the features of extracted parasite egg microscopic images. The recognition accuracy of the two classifiers is analyzed, and the recognition rates of the two classifiers are compared to select the high precision and high efficiency classifiers. Through the research and experiment in this paper, it is proved that the automatic recognition technology of parasite egg microscopic image based on machine vision is feasible and effective, and has certain practical value in medicine.
