Segmenting disease spots in leafs is achieved by Comprehensive Color feature (CCF), grayscale conversion and region growing method is discussed. Segmenting disease spots under real-field conditions with uneven illumination and clutter background has been a major challenge. Uneven illumination issues solves by applying Excess Red index, H component of HSV and grayscale conversion by using SVD, clutter background problem solves by applying region-growing method. Performance of these methods is calculated using precision, and its accurate segmentation is 89% under real-field condition. |
