| Abstract | Human chromosomes contain important information for cytogenetics analysis. Cytogeneticists compare their patient's chromosome images against the prototype human chromosome band patterns. Computer enhancement of chromosome bands in the images facilitate visualization and karyotyping. Currently available systems employing conventional convolution filtering are similar to photomicroscopy in their ability to support the detection of band pattern alterations. Improvement in visualization quality and capability of effective band enhancement for detail analysis would significantly increase the cost-effectiveness of these instruments. In this paper we describe a new technique developed for human chromosome image enhancement, based on the cubic-spline wavelet transform and multiresolution image analysis. Under this approach, chromosome band pattern features can be characterized compactly in the transform domain by a multiresolution image representation. Enhancement of these features can be achieved with designed flexibility in scale, orientation, location, and degree of enhancement, by analyzing and selectively processing the transform coefficients. This technique promises improved image enhancement means to assist the evaluation of chromosome abnormalities in clinical samples. Experimental results are presented to exemplify the feasibility of the approach. |

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.
