  • 摘要:We describe a contour-based image representation using a wavelet transform and a contour-domain image editing system that we developed using the proposed representation. Contour-based image representations depict the properties of the image edges and are invertible between an image and its representation. The contour-based image representations based on the wavelet transform have been proposed for many image-processing tasks. However, the low-frequency component of the wavelet transform defines entire pixels for an image and is not associate with contour geometry. We introduced a sampling to the low-frequency component of the wavelet-based image representation and proposed a contour-based image representation that describes an image with only the edge-information associated with the contour geometry. We describe examples of the image recovery from the proposed representation and present an interactive image editing system based on the proposed representation.
