Abstract :
Most modern consumer cameras are capable of video capture, but their spatial resolution is generally lower than that of still images. The spatial resolution of videos can be enhanced with a hybrid camera system that combines information from high-resolution still images with low-resolution video frames in a process known as super-resolution. As this process is computationally intensive, we propose a camera system that uses the spatial and temporal information measures SI and TI standardized by ITU as camera parameters to determine during capture whether super-resolution processing would result in an increase in perceived quality. Experimental results show that the difference of these two measures can be used to determine the feasibility of super-resolution processing.
