| Abstract | This paper present a novel method for robust and early Cercospora leaf spot detection in sugar beet using hybrid algorithms of template matching and support vector machine. We adopt three-stage framework to achieve our research target: first, a plant segmentation index of G-R is introduced to distinguish leaf parts from soil-contained background for automatic selection of initial sub templates, second, we adopt a robust template matching method called orientation code matching (OCM), which could not only realize the continuous and site-specific observation of disease development, but also shows its excellent robustness for nonrigid plant object searching in scene illumination, foliar translation and small rotation, afterward, we employ a machine learning method of support vector machine (SVM) for robust and early disease classification by a color-based feature named two dimensional (2D) xy-color histogram, which has stable ability to classify disease against various illumination changes. The indoor experiment results demonstrate the robust performance of our proposed method for early disease detection against complex changes of external environment. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
