We provide a vision-related image deformation method based on Moving Least Squares (MLS) and visual saliency map. As the improvement of image deformation using MLS, we propose a new weight function to improve the MLS image deformation. A visual saliency-related deformation weight definition is proposed to ensure deformations are more easily to kept local shape on high visual saliency region and changed...
We propose a new effective shape descriptor, chord context, for shape description in content-based image retrieval. For a shape, the chord context describes a frequency distribution of chord lengths with different orientations. The histograms which represent the chord context are compacted and normalized into a feature matrix. Unlike other shape representation schemes, the proposed scheme is able...
