The NHK Broadcasting Technology Research Institute published a technical demonstration of applying super-resolution technology to image codec at the "Technology Exhibition 2011". This technology avoids excessive compression ratio during encoding to reduce image quality by "adding" video reduction (down-conversion) and super-resolution (up-conversion) based on the original image encoding and decoding technology. Deterioration. The specific method is to first perform image reduction processing on an image with high resolution. The image is then encoded using the original H.264. After transmission, it is decoded by H.264. At this point, the size of the image is reduced, so it is necessary to restore it to the original image size using super resolution technology. The advantage of this is that the codec can be improved with additional techniques and systems without changing the original codec technology. A reasonable compression ratio can be selected for encoding, which has the effect of reducing image quality deterioration. The image quality deteriorated as the image is reduced. The reason is that various parameters and image quality compensation information used when the image is reduced are transmitted as auxiliary information to a different image receiving end than the image data for use in restoring the image using the super-resolution technique. The reason why the above technology can be realized is because of the development of super resolution technology. "The original super-resolution technology has technical problems in edge processing" (narrator). Recently, the subject has been greatly improved, so the application was realized. However, the current problem is that data processing is complicated, and the load and delay during processing are large. In general, the more complicated the encoding processing of the image encoding technique, the larger the processing scale, the more the image compression effect with less deterioration can be obtained. Whether this method is really superior to the above general codec improvement method will be a topic to be explored in the future. “Water flow priority†or “edge priority� This time, NHK Technical Research proposed two methods, A and B, as specific installation methods. Method A is a method of changing the pixel compression ratio according to a pattern when the image is reduced. The complex part of the pattern reduces the compression ratio, while the part with a simple pattern boldly separates the pixels to greatly reduce the image. Thus, the reduced image becomes a deformed image in which the compression ratio is significantly different from the pattern. This is used when data with different compression rates is sent as auxiliary information to the receiving end and recovered using super-resolution technology. "Method A is suitable for reproducing random dynamic data such as the flow of water and the reflection of light. However, many problems need to be solved in the hardware installed in the processing circuit." Method B is a method in which the image degradation information originating from the image reduction and encoding processing algorithm is grasped by the transmitting end and used to optimize the image reduction technique. Specifically, the image data reduced by the encoding is first decoded by the transmitting end and restored by the super-resolution technique. Then, the restored image is compared with the original input image, and the parameters at the time of image reduction are adjusted to minimize image degradation due to the image processing algorithm. The degradation information is also sent to the receiving end as auxiliary information. Method B "is best suited for edge processing where images are not continuously changing. Sometimes techniques such as wavelet analysis are easy to implement hardware circuits, and it is easier to install" (narrator). According to NHK Technical Research, the method of combining Method A and Method B will be discussed in the future. An overview of new image coding techniques using super resolution technology. It can be seen from the demonstration that the image output by the new technology is significantly reduced compared to the image formed by the original coding technique.
