| Outline of Final Research Achievements |
The results of super resolution using multiple images depends on the accuracy of translational displacement between images. For this reason, the accuracy of the discrete cosine transform (DCT)-sign phase correlation which uses only signs of DCT coefficients was clarified using the images that are captured by a commercial-off-the-shelf product camera and an industrial product camera. and the fundamental study for super resolution in the DCT domain was completed. Also, the difference of the accuracy between simulated images and captured images was clarified. Through theoretical analysis of the correlation between signals, the double correlation was developed, which is useful for matching of a reversed signal.
