Problems solved by technology

However, algae cells are generally long, and multiple algae cells may cross together during the cultivation process, resulting in the inability to accurately segment the intersected algae cells, which in turn leads to the inability to accurately count the number of algae cells

Embodiment Construction

[0050] The technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of this application.

[0051] Before introducing the implementation of this application, some preparatory work needs to be performed: Generally, the concentration of algae cells in the algae cell solution is relatively high. In order to carefully examine the algae cells under the microscope, the algae cell solution needs to be diluted by a certain multiple. Then, a certain volume of algae cell solution diluted by a certain multiple is placed on the objective lens of the micros...

Abstract

The invention provides an image processing method and device. The method includes: acquiring a target image including algal cells; binarizing the target image to obtain a target gray image; extracting connected areas in the target gray image, and calculating area of each connected area; dividing preset algal area by the area of each connected area to obtain a quotient of each connected area; using a sum of the quotients of the connected areas, as the amount of the algal cells included in the target image. The algal cells intersecting together are not subjected to image splitting, thus, the number of the algal cells can be accurately counted, and accuracy of counting the algal cells is improved.

Description

Technical field [0001] This application relates to the field of image processing, and in particular to an image processing method and device. Background technique [0002] In the research of algae analysis in the field of biotechnology, technicians will actively cultivate algae cells. In order to clarify the reproduction of algae cells, it is necessary to count the number of algae cells. At present, industrial cameras are used instead of traditional microscope eyepieces to magnify and image the sample solution of algae cells, and then use image processing methods to calculate the number of algae cells in the imaging area. [0003] The method of image processing and counting in the prior art is to perform image segmentation on the area containing algae cells in the imaging area to generate multiple segmented areas, and then count the number of segmented areas as the number of algae cells. However, the algae cells are generally long, and multiple algae cells may cross together duri...
