Abstract
In this paper, a new algorithm for segmentation of frog-eye spot lesions on tobacco seedling leaves is proposed. Segmentation algorithm consists of mainly two steps. First step is to approximate lesion extraction using contrast stretching transformation and morphological operations such as erosion and dilation. Second step refines the outcome of first step by color segmentation using CIELAB color model. We have also conducted a performance evaluation of segmentation algorithm by measuring the parameters such as Measure of overlapping (MOL), Measure of under-segmentation (MUS), Measure of over-segmentation (MOS), Dice similarity measure (DSM), Error-rate (ER), Precision (P) and Recall (R). In order to corroborate the efficacy of the proposed segmentation algorithm, an experimentation is conducted on our own dataset of 400 segmented areas of tobacco seedling leaves which are captured in uncontrolled lighting conditions. Experimental results show that our proposed segmentation algorithm achieved best average DSM and MOL accuracy as compared to our previous segmentation algorithm.
