Abstract: We present the use of deformable templates for image retrieval where a template line drawing sketch can be detected in the target image, irrespective of its position, size, rotation, and shearing transformations. First, a coarse scale template is searched in the target image using a modified version of the Generalized Hough Transform to find candidate potential targets at different positions, orientations, and size. The candidate positions are then used to find a match at the full-scale version of the image where the template also undergoes a grid shearing transformation. The deformed template contour is matched with the target by measuring 1) the smoothness of the matching vector between edge elements of target and transformed template and 2) the similarity in contour tangent direction at that edge element. The deformation parameters are updated via relaxation using the Gibbs Sampler on the energy cost function to find the best match between the deformed template and the target image. At the full image scale, the matches that meet the preset cost criteria are reported as the search result. We have experimented with several test images to demonstrate the effectiveness of this image retrieval method, the results of which are included in this manuscript.
