| Abstract(in English) | A method combining a Based learning method and ShockFilter for Total Variation (TV) regularization, which is one of super-resolution methods, is a super-resolution technique that realizes strong edge sharpening and reconstruction of fine patterns . However, there is a possibility that ShockFilter degrades image quality depending on the processed image, and the case learning method has a problem that the processing time becomes enormous due to a large amount of correlation calculation. These problems are applied to various images, and it is difficult to apply it to moving images etc. where real time property is required. In this research, by applying Bilateral Filter as pre-processing of ShockFilter, we realized speedup of case learning method by improving image quality degradation and using multi-frame. As a result, we succeeded in improving the image quality by not causing jaggies compared to conventional edge sharpening, and achieving a total speed of 2.8 times as fast as the conventional method, and.confirmed that it can operate sufficiently in real time moving images. |
