| Abstract | Methods of plant nutrient status analysis using the leaf image features like color, textures and shape have been proposed in recent years, which facilitate the rapid development of nondestructive detecting techniques that are better than traditional soil and plant detection in many ways. However, most of these methods suffer from the following drawbacks: 1) device dependent due to the distortions caused by different imaging systems, thus making the detecting results of the foliar image captured with different devices apparently inconsistent; 2) sensitive feature extraction due to varying ambient interference of illuminations directly leads to unstable detection result; 3) qualitative classifier that is hard to achieve precision fertilizer guidance. In this paper, we present a system that addresses the issues using a normalized agro-chemical model and an implicit correction on color and shape distortions of the foliar images. The operation records have shown that the detection result can be obtained at least one week ahead of the traditional observation, and its computational error of the nutrient deficiency is within the range of the plant fertilizing guidance. |

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.
