Precise Medical Image Retrieval Using Spectral Analysis

Generally in medical field, we prefer shape based segmentation approach for image retrieval. Image retrieval basically performed to achieve faster data transfer (or) proper resource utilization for image processing. For the estimation of the contour region, an 8-region neighborhood growing algorithm is used. Once the contour is detected, the curvature for the obtained contour is calculated. Spectral transform offers good properties for data retrieval. Spectral descriptors are more efficient in describing shapes, a spectral transform approach is proposed Keyword- Image Retrieval, Spectral Transform, Contour Representation.
