There is need for developing technique such as automatic plant disease detection and classification using leaf image processing techniques. Mettre au point des algorithmes de segmentation de haut niveau (chaque région est un objet sémantique) est encore un des thèmes de recherche les plus courants en traitement d'images. 3 Literature review of relevant machine learning techniques. Unsupervised classification yields an output image in which a number of classes are identified and each pixel is assigned to a class. At the end, the reviews showed the improvement of image classification techniques such as to increase accuracy and sensitivity value and to be feasible employed for computer-aided-diagnosis are a big challenge and an open research. In this survey, we provide an overview of often used ideas and methods in image classification with fewer labels. The image is classified to six classes including water, vegetation, thin partial clouds over ground, thin clouds, low/middle thick clouds and high thick clouds plus unknown class for supervised classification. In general, the image classification techniques can be categorised as parametric and non-parametric or supervised and unsupervised as well as hard and soft classifiers. 2 Related Literature.
