Novel texture synthesis methods and their application to image prediction and image inpainting (2011)
Abstract / truncated to 115 words
This thesis presents novel exemplar-based texture synthesis methods for image prediction (i.e., predictive coding) and image inpainting problems. The main contributions of this study can also be seen as extensions to simple template matching, however the texture synthesis problem here is well-formulated in an optimization framework with different constraints. The image prediction problem has first been put into sparse representations framework by approximating the template with a sparsity constraint. The proposed sparse prediction method with locally and adaptive dictionaries has been shown to give better performance when compared to static waveform (such as DCT) dictionaries, and also to the template matching method. The image prediction problem has later been placed into an online dictionary learning ... toggle 8 keywordssignal processing – image processing – image compression – coding – sparse representations – dictionary learning – neighbor embedding – image inpainting
