Figures and FG/BG-selective filtering

Some figures for the write-up:

The next two figures show the results of flash/no-flash integration (still very hacked, since hardware support for timing flash isn't available in the current FCam release). The alternating flash/no-flash shots are used to determine foreground (FG) from background (BG); filter is then applied only on FG or BG.

Some more figures:

The remaining figure will be the perf measurements.

Live flash/no-flash integration

We implemented a very hacked version of flash/no-flash integration. The difficulty is in maintaining proper synchronization between successive flash and no-flash shots.

Nevertheless, with the hacked flash toggle implementation, a joint bilateral filter was set up. It would also be interesting to do foreground-background detection by flash/no-flash difference images. There can be a lot of neat effects enabled by this technique, e.g. cartoonization applied only to foreground (or background), or synthetic blurring of background, etc.

[March 6th]: Alas, Nvidia just confirmed that the two methods for Flash control are lacking: (1) FireAction does not support timing in the current FCam implementation; (2) TorchAction is completely asynchronous and hence this is not really the means to get an alternating stream of flash/no-flash.

If/when Nvidia releases stereo camera, we might try shuffling the two stereo cams to the two SharedBuffers.

My walk to Stanford campus this morning. Will take more shots later when the sun is in a more favorable spot relative to the Memorial Church:

Was inspired to take a short walk outside today:
