  • This curious image is a digitized x-ray of a muscovy duck. It provides a demonstration of a restoration on a non-optical image.
  • Restored Image. As you can see, much greater detail is seen when the degration is removed. (The straight line on the right was not orignially imaged, but superimposed for demonstrative purposes. Thus it appears distorted after deconvolution.)
  • A sonogram of the baby boy's feet . This image is a screen shot that was printed out on paper, and then digitally scanned.
  • Restoration of the sonogram. This restoration could be further improved if the data was processed before printing the hard copy of the image.
  • A sonogram of the baby boy's fist . This image is a screen shot that was printed out on paper, and then digitally scanned.
  • Restoration of the sonogram. This restoration could be further improved if the data was processed before printing the hard copy of the image.
  • This is a digital dental panoramic X-ray of human teeth. The original image had a bit depth of 8 bits, and had jpeg compression.
  • Restored Image. Despite the low bit depth, the resolution of this image is drastically improved. However, if you closely at the gray areas, you can see some artifacting that results from the jpeg compression.
  • Ultrasound showing my son's profile before birth.
  • A restoration of the ultrasound.
  • This is another digital X-ray of teeth, pretty typical of all digital X-rays found on many websites.
  • Restored Image. The deconvolved image was noisy. So we applied a noise reduction filter to reduce noise and emphasize the main features.
  • This image is an x-ray of a penguin.
  • Restored Image.

Top: This curious image is a digitized x-ray of a muscovy duck.

 

Bottom: Restored Image. As you can see, much greater detail is seen when the degration is removed.  (The straight line on the right was not orignially imaged, but superimposed for demonstrative purposes.  Thus it appears distorted after deconvolution.)  A deconvolution of a penguin X-ray is also included in the slide show above.

This is a digital scan of an ultrasound image that was printed on paper.  The feet belong to my oldest son.  The restoration is noticeable, but not dramatic.  With each step that occurs before the scanning, there is potential for information about the blur function to be lost.  The slideshow includes two other ultrasound scans, one for each of my other kids.
