Embodiment 1
[0042] A tobacco field image segmentation method, comprising the following steps:
[0043] S1: Convert the collected tobacco field color images into Lab and YUV color space images respectively;
[0044] S2: Then the Lab color space image is subjected to threshold segmentation using the Ostu method, and the YUV color space image is segmented using the weighted fuzzy entropy method;
[0045] S3: Merge and filter the image segmented by the Ostu method and the image segmented by the weighted fuzzy entropy method to obtain a segmentation result.
[0046] In step S2, the process of thresholding the Lab color space image using the Ostu method is as follows:
[0047] Convert the collected tobacco field color image from the RGB color space to the LAB color space, select the a component of the LAB color space and use the Ostu method to segment the background of the image:
[0048] 21) Calculate the grayscale probability distribution of the a-component image:
[0049] p(k)k=0,1,2,...,...
