NUTIK is the non-uniform version of TIK, Temporal Imaging from Kentucky. It can create and process IMEV (IMage EVolution) TDCI (Time Domain Continuous Imaging) data streams that record a waveform per pixel describing how the light level varies over time. From the IMEV TDCI data, TIK can then render virtual exposures for any time period, selected after capture, that is covered by the waveforms. NUTIK can do that too, but it also allows specification of how the exposure contribution can change over time, and it allows multiple different formulas for different regions identified by a mask. For example, NUTIK was used to produce the above image from a single capture of a ball rolling down an incline,.
NUTIK is described in:
The NUTIK software (which basically replaces tik, so it compiles to an executable by that name) is available here. Releases are listed in most recent first order, so the first is the current release.
Additional materials will soon be posted here.
The only thing set in stone is our name.
