1.2 Distortion Characterization
- Limits to global brightness or contrast (easily
compensated for automatically)
- Varying brightness over the whole image dure to: tilt, glare,
charge buildup, reflection, polarization, etc.
- Regions of saturated (light or dark) pixels - in the extreme
(when fully saturated) there is no way to recover the lost information
- Out of focus
- Image shape distortion (e.g. bow-tie or trapezoidal) - can be due to stray, or
out of calibration or alignment magnetic fields in some imaging hardware
- Motion blur (not likely in FA context)
