SPIE Co-sponsored Short Course Imagery must be digitized before processing.
Image processing can restore degraded imagery and enhance specific image features.
The success of image processing depends upon the original digitization process and the subsequent reconstruction into an analog image. Simply stated, image processing cannot be studied in isolation. You must know the limitations of the camera that created the image and the limitations of the display media. You cannot extract information that is not present. Any attempt to do so creates artifacts.
