Abstract

The invention relates to the technical field of image processing, provides a method and device for recognizing diatom types of extracted diatom regions, and aims at directly extracting imaged diatom region images without removing impurities in and around diatoms through complicated experimental means. The method for recognizing diatom types of extracted diatom regions comprises the following stepsof: obtaining an image of a to-be-recognized diatom; taking an alga fitting contour frame, matched with the to-be-recognized diatom, selected according to the image of the to-be-recognized diatom asa diatom ROI (region of interest); extracting a to-be-recognized diatom image corresponding to the to-be-recognized diatom from the image of the to-be-recognized diatom according to the diatom ROI; and carrying out feature recognition on the to-be-recognized diatom image so as to determine a type of the to-be-recognized diatom.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a method and device for identifying diatom types in extracted diatom regions. Background technique [0002] Diatoms are a kind of unicellular plants with chromophores, often composed of several or many individual cells connected into various groups. Diatoms come in a variety of forms. [0003] At present, the detection of diatoms needs to process the images of diatoms and extract diatom regions for detection. Existing methods mainly focus on the extraction of diatom regions from simple background optical microscope images. These methods need to use complex experimental means to clean and remove the fine sand and particles in and around the diatoms before imaging the diatoms, and then perform optical microscope imaging on the clean diatoms. This preprocessing method is complex and requires a lot of manpower to complete. At present, there is an automated metho...
