High Dynamic Range Imaging

posting some results (need to complete later on)

grade so far (0-10): 8.5, malapit na!:)

This is a Plasma Image seen thru a viewing Window:

These are Plasma Images taken with the same camera but with different exposure times per picture:

For each image, 5 pixel locations were chosen within the viewing window,(row, col) =

800,600

600,900

1000,900

1000,370

600,370

these locations were chosen so that we have some locations which are dark and some which are bright to capture a wide range of possible pixel values.

and for each of these pixel locations, we have varying pixel values as we change from different images(i.e. varying exposure times)

But, for each exposure time, we can get the log of delta T (T=exposure time), and plot the pixel values (same mark = same pixel location) as we change exposure times as shown below:

These points can actually make up the new "transfer function" to increase the dynamic range of our camera by calculating a best fit for the group of points above and combining all "sub_groups" into one smooth function that "extends" both ranges of the pixel values and the exposure times.
