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
