Image Flickering - a Method for Visually Comparing 2D Gels
- Flickering is the rapid alternate display of two
images which overlay the same visual space
- Images are locally aligned by moving one image with
respect to other one while flickering
- Images appear to fuse together if:
- Flicker rate is adjusted to (0.1 to 1 second)
for type of material and person viewing
- User is reasonably close to display
- Local regions are well aligned with most features
aligned
- Differential flicker (display one image longer than
the other) useful for comparing light and dark samples
- Mechanical and computer flickering was used in
astronomy, 2D gel analysis, and other image comparisons
