image reconstruction

Neil Fazel
102 posts
I have an image created from placing a rectangular mask in front of an intense source of light. The mask has gaps (slots) in it, so looking at the image the human eye can still tell how the original intensity would have been without the mask; it has circular or elliptical symmetry and declines radially moving away from the center. Can this original intensity (i.e. without the mask) be reconstructed in ImageJ? Is ImageJ the right tool?

It seems you're looking to operate a 2D interpolation function on an image.

I don't think ImageJ is necessarily what you need, since it's suite of
functions are higher level and applicable for biological image
processing.
While the most suitable tool would depend on your familiarity (and
others in your lab) some options to consider are:
- python and numpy.  Here is the scipy interpolate page:

- matlab
