The present invention provides an image segmentation method and apparatus. The technical scheme comprises: a step or an apparatus for extracting an a component image in a Lab color space after converting the target image into the Lab color space; a step or an apparatus for detecting an edge of a segmentation target in the a component image to extract a closed contour curve of the segmentation target; a step or an apparatus for performing padding processing and opening operation processing on the contour curve to obtain a binary image covering the segmentation target; and a step or an apparatus for performing the intersection operation on the binary image with the target image to obtain a segmentation image of the target image. According to the technical scheme of the present invention, automatic segmentation of crop leaf images under natural conditions is realized, the technical scheme is simple and practical, and the segmentation precision and efficiency of crop leaf images in the natural environment are improved.
Description
technical field [0001] The invention relates to the field of agricultural information technology, in particular to an image segmentation method and device. Background technique [0002] Crops are susceptible to various diseases and insect pests during their growth and development. Image processing methods and computer vision technology can be used to identify and judge images of crop diseases and insect pests, and automatic segmentation of crops and complex backgrounds is the first step in image processing and analysis, and it is also a crucial step. The quality of the segmentation results directly affects It affects the accuracy of subsequent image feature extraction and target recognition. [0003] The image acquisition of crop leaves in a natural environment is easily affected by factors such as complex backgrounds, weather changes, and acquisition angles, which make the acquired images have the characteristics of various contents, uneven illumination, shadows, and parti...
