Embodiment Construction

[0022] In order to make the purpose, technical solution and advantages of the present invention clearer, the implementation manners of the present invention will be further described in detail below.

[0023] This method will break through the existing method of independently modeling each type of algae in the background technology, and use a multi-task joint learning model to simultaneously learn models for multiple algae, thereby solving the dependence of the first type of method on high-resolution visual features , and can avoid the second type of method's dependence on big data and high computational complexity.

[0024] 101: Preprocessing the algae image, and obtaining the processed algae image;

[0025] Among them, for the input algae image (one image only contains one algae cell, such as figure 1 There are no special restrictions on the acquisition device, camera parameters, image storage format, image resolution and other parameters, as well as the type of algae image...

Abstract

The invention discloses an automatic classification method for algae cell images. The automatic classification method includes the following steps: preprocessing the algae image, obtaining the processed algae image; and extracting the visual features of the algae image according to the processed algae image, Obtain the feature vector represented by multi-feature fusion; classify all algae cells according to category, and extract a specific proportion of cell images in each type of cell as a training set for subsequent model learning; construct and solve the objective function of the multi-task learning mode; use training The resulting model makes predictions on the test data. The invention reduces the computational complexity and improves the classification rate of algae cells.
