State-Based Motion Transitions using Framespace Interpolation

by Golam Ashraf
Results supporting Ph.D. Dissertation, (SCE, NTU, Singapore)
(Submitted: Sep. 2001; Degree Awarded: June 2002)

The material here has been organized under two broad sections:
A) Experimental results in support of the thesis (Experiments and Result Highlights)
B) Additional material on functional components of the MAFI framework (General Overview)

Section A has been further decomposed into the following threads:
1) Detailed set of results from the 20 chosen test interpolation blocks + transition chaining +  metadata
2) A concise presentation of results, summarizing inferences and a select set of rendered results.

The three threads shown in the navigation bar above are navigable from the combo-boxes. Pls. ensure that Javascript is enabled in your browser, and follow the hints for a smooth ride through all the results. It will be easier to cope with the large amount of results presented in the transition cases, by browsing the Result Highlights-->Transition Highlights section first, which groups the results of the Transition Cases semantically and then provides a summary presented in perspective of the thesis.

The experimental cases have been demonstrated in wireframe, from a perspective that presents strong silhouettes of the result. Both telescopic and wide-angle views are provided for each animation, unless there is very little horizontal motion to justify a wide angle perspective. In some cases, real life examples are provided for comparison. In the spirit of true research, none of the results have been massaged in order to accurately evaluate the limitations of the framework. Some of the artifacts evident in section two can be easily removed by tweaking the transition function, but even this has been avoided. All animations are encoded in the Cinepac Codec by Radius AVI format for portability. Almost all images are linked to animations, so please click them to view the results. The presentation format in the experiments section is as shown below. See hint for irritation-free browsing of clips.

Caution: Some animations do not show on the browser for strange reasons. Disable your browser playback plugin (link files to mplayer32.exe) or view  these files manually on the mediaplayer. (Locations of the file appear on the status bar upon cursor-placement on links)
Hint: A "new" window is created for the animation clip in case you have a browser playback plugin. Keep this manageably resized at one corner of the monitor to prevent it from popping up repeatedly.
