A Cucumber Disease Recognition Method Based on Cucumber Leaf Symptom Image Processing

Abstract

A cucumber disease recognition method based on cucumber leaf symptom image processing, first segment the cucumber disease leaf lesion image, then extract the image recognition features of cucumber disease leaf, then reduce the dimensionality of the feature vector, and finally identify the cucumber disease. The invention overcomes the existing methods and technologies for identifying cucumber diseases. Due to the complex image components of cucumber diseased leaves, the arrangement of diseased spots on cucumber diseased leaves is irregular, and the color is different, and the shapes and colors of leaf diseased spots of different disease types are not the same. The reason is that the recognition rate of cucumber diseases based on leaves is not high and the recognition effect is unstable. It has the advantages of fast feature extraction, high recognition rate, stable recognition effect and strong practicability.

Description

Technical field [0001] The invention relates to the technical field of the application of image processing and pattern recognition in cucumber disease recognition, in particular to a cucumber disease recognition method based on image processing of cucumber leaf symptoms. Background technique [0002] Cucumber is widely distributed in China and even in many parts of the world. It is one of the main vegetables eaten by residents of many countries and has many benefits to the human body. However, cucumber is a kind of susceptible cucumber, and there are more than ten kinds of common cucumber diseases. Accurately judging the types of cucumber diseases is the prerequisite for cucumber disease control. Traditional cucumber disease detection basically relies on the visual estimation of agricultural producers. This detection method has many shortcomings, such as strong subjectivity, slow recognition speed, high recognition intensity, high false recognition rate, poor real-time performan...

But detecting cucumber diseases by leaf symptoms is not an easy task

The reasons are: (1) There are many kinds of cucumber diseases at present, resulting in a variety of symptoms on the diseased leaves; (2) With the promotion of new high-quality cucumber varieties and diversified planting in my country, there will be more opportunities for the occurrence of more cucumber diseases. Due to the lack of suitable conditions (such as greenhouse planting, etc.), the incidence of cucumber diseases is on the rise.

These conditions also bring challenges to the research of cucumber disease detection methods based on cucumber leaf symptoms.
