Vegetable leaf disease image segmentation method and system and computer readable storage medium

Abstract

The invention discloses a vegetable leaf disease image segmentation method and system and a computer readable storage medium. The vegetable leaf disease image segmentation method includes the following steps that 1, superpixel clustering processing is conducted on vegetable leaf images to obtain superpixel segmentation images; 2, significance region detection processing is conducted on the superpixel segmentation images to obtain lesion significance images; 3, the lesion significance images are processed to obtain non-lesion pixel sets; 4, region growing an region merging are conducted on pixel points in the non-lesion pixel sets to obtain lesion areas and normal areas of the vegetable leaf images. By the adoption of the vegetable leaf disease image segmentation method and system and the computer readable storage medium, leaf diseases in greenhouses can be rapidly and effectively detected and extracted under the conditions that no chemical reagents are in use and diseased vegetable leaves are not damaged, and therefore the vegetable leaf disease image segmentation method and system and the computer readable storage medium can be well applied in monitoring greenhouse vegetable diseases.

Description

technical field [0001] The invention belongs to the field of image processing, and relates to image segmentation technology and significance detection technology, in particular to a vegetable leaf disease image segmentation method, system and computer-readable storage medium. Background technique [0002] In the process of vegetable cultivation, various diseases will occur to crops due to environmental stress, microorganisms, viruses, bacteria, etc., which will lead to a decline in vegetable quality and cause major economic losses. Usually, farmers rely more on their own experience to judge the types of vegetable diseases and their control methods, which is highly subjective and less effective. At the same time, blindly spraying excessive pesticides to prevent and control vegetable diseases will cause pesticide residues and affect agricultural products. Therefore, early detection and early control of crop diseases are the key to increasing crop yield and reducing the use of ...

[0002] In the process of vegetable cultivation, crops will suffer from various diseases due to environmental stress, microorganisms, viruses, bacteria, etc., which will lead to a decline in vegetable quality and cause major economic losses.

Under normal circumstances, farmers rely more on their own experience to judge the types of vegetable diseases and their control methods, which is highly subjective and less effective. At the same time, blindly spraying excessive pesticides to prevent and control vegetable diseases will cause pesticide residues and affect agricultural products. Therefore, early detection and early prevention of crop diseases are the key to increasing crop yield and reducing the use of pesticides
