| Abstract | In change detection analysis, it is important to reduce the influence of image misalignment in order to produce image changes that are relevant to the user. The accuracy of change detection solely depends on the image registration accuracy yet image misalignment is still a major challenge in change detection analysis. In change detection analysis, if change detection is performed on misaligned images, problems such as false changes and missed changes may occur which strongly affect the actual change detection accuracy. Object based change detection has been reported as one the best way to reduce the influence of effects of image misalignment. This is because of its capability to deal with misregistration errors that result into false change and missed changes. In this paper, a tiled object based change detection technique is proposed to reduce the influence of image misalignment on the tile pixel based change detection. Threshold level based fuzzy c-mean clustering is adopted during segmentation and classification, as well as image differencing is used to obtain a change image. Experiments show that the proposed method significantly reduces the false changes (commission error (from 16.67% to 0.7059%, 40.63% to 1.3881%, 31.58% to 2.1034%) in tile pixel based change detection meaning the method is robust to noise. The experimental results show that the method is capable of producing a high accuracy rate. |

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.
