[0033] In order to make the object, technical solution and advantages of the present invention clearer, the method of the present invention will be explained in detail below in conjunction with the accompanying drawings. It should be understood that the specific examples described here are only used to explain the present invention, not to limit the present invention.
[0034] The present invention proposes a conformal mapping sparse expression method for image and video scene content. By introducing conformal mapping rules, the method keeps the local angle information between adjacent samples to the greatest extent, and obtains a more concise and expressive method. Dictionary; using the dictionary generated by this method for video image editing, the reconstruction results can better maintain the original local structure, and enhance the visual effect and realism of the generated results. Meanwhile, the method is applied to three typical applications, including image super-re...
