Dermoscopy, a non-invasive imaging technique has been significantly used by the doctors and radiologists for the early diagnosis of the various skin disorders. The characteristically similar nature of the melanocytic skin lesions specifically melanoma and dysplastic nevi make the diagnosis more subjective and time consuming, even for expert clinicians. Computer aided diagnostic system has a great...
Among the skin cancers, malignant melanoma is of by far the most deadly type. For the early diagnosis of melanoma, computer-aided diagnosis systems for the classification of dermoscopic images have been developed. For accurate image classification, the segmentation of skin lesion area is of prime importance. In this work, mathematical morphology has been used for segmentation for proper identification...
The tomato (Lycopersicon esculentum) is an herbaceous, usually sprawling plant which belong to Solanaceae or nightshade family. Genetic evidence shows that the progenitors of tomatoes were herbaceous green plants with small green fruit. There are a great many (around 7500) tomato varieties grown for various purposes. Their identifications had been studied using various laboratory methods. The morphological...
This paper presents a new anisotropic diffusion method for multi-valued images. The colored flowers are segmented from the background. In my diffusion technique the edge stopping function is computed as inversely proportional to the weighted sum of gradients of color components. The value of edge stopping function tends to zero as the weighted sum of three color gradients becomes large. The other...
