| Zusammenfassung: | An image processing apparatus and method are provided which obtains an image captured by an image capture device and stored in a memory, extracts one or more regions of interest in the obtained image, normalizes the extracted one or more regions of interest to be at a same scale or some predefined scales, extract the frequency information of regions of interest, determines a sharpness of the obtained image by aggregating the frequency information in each of the one or more extracted regions of interest, and labels the obtained image with the determined sharpness score. |
