Embodiment

[0022] The parasite egg image registration method of the present invention comprises the Harris corner algorithm and the image registration process, and also includes the following steps:

[0023] S1. Sampling parasite eggs multiple times, specifically, collecting sample images through a camera at a rate of 10-30 images per hour, and then selecting an optimal image in each sampling interval according to the parameters of definition and noise. The images form a registration image set, and the remaining images are used as source images for testing;

[0024] S2, perform the same preprocessing on the source image and the registered image, and use basic statistical features to perform preliminary image rotation, translation, and scale transformation to remove redundant noise;

[0025] S3, using the Harris corner algorithm to perform Harris corner detection on the source image and the registration image, and record the corner coordinates;

[0026] S4, take the corner point as the c...

Abstract

The invention discloses a parasite egg image registration method, and relates to parasite egg image registration. The parasite egg image registration method comprises a Harris corner point algorithm and an image registration process, and further comprises the following steps: S1, sampling parasite eggs for multiple times, specifically, setting a registration image set of a source image set; S2, carrying out the same preprocessing of the source image and the registered image, carrying out the preliminary image rotation, translation and scale transformation through the basic statistical features, and removing the redundant noise; S3, performing Harris corner detection on the source image and the registration image by using a Harris corner algorithm, and recording corner coordinates; S4, setting a registration area; S5, calculating a correlation coefficient of a registration area of the source image and the registration image; S6, judging the matching degree of the source image and the registration image by using the correlation coefficient; and S7, entering an image registration process. According to the invention, the identification accuracy of parasitic ova is improved by using animage registration method; and the parasite egg image registration method has good feature invariance, uniqueness, stability and independence.

Description

technical field [0001] The invention relates to image registration of parasite eggs, in particular to a method for image registration of parasite eggs. Background technique [0002] Image registration is the process of superimposing two or more images of the same scene obtained by different time, different viewing angles, and different sensors. At present, there is a problem that the difference of parasite eggs is small, and the image quality is degraded due to excessive interference. Contents of the invention [0003] The technical problem to be solved by the present invention is that currently there is a problem that the difference of parasite eggs is small, and the image quality is degraded due to excessive interference. The purpose is to provide a method for image registration of parasite eggs to solve the above problems. [0004] The present invention realizes through following technical scheme: [0005] The parasite egg image registration method includes the Harris...
