| Abstract | Image segmentation is a partitioning of an image into constituent parts using image attributes such as pixel intensity, spectral values, and/or textural properties. Image segmentation produces an image representation in terms of edges and regions of various shapes and interrelationships. It is a key step in several approaches to image compression and image analysis. The author has devised a hybrid image segmentation approach that combines region growing and boundary detection. The core of this image segmentation approach is an iterative parallel region growing algorithm that the author has developed over the past several years. The question of where to stop the region growing process is solved by not allowing the region growing process to grow regions past boundaries defined by a boundary detection algorithm. The author has found an edge detector based on an optimal difference recursive filter to be most suitable for this boundary detection. This edge detector provides highly localized edge boundaries and is relatively insensitive to noise. It also provides a convenient threshold parameter through which an application appropriate edge density can be selected. |

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.
