Using several low-resolution images can provide better quality of a high-resolution image. The process of reconstructing a single high-resolution image from several low-resolution observations is called as superresolution.
Three directions are studied in this project:
- High-quality superresolution based on regularization methods.
- Non-iterative superresolution. A method of weighted median averaging is used to combine pixel values of given low-resolution images.
- Superresolution for video sequences. Two images are used here for high-resolution frame construction: current low-resolution frame and previous high-resolution frame.
