has an extension of an .amc and defines the actual channels of the animation. Each
frame starts with a line declaring the frame number. The next line contains the data
for the bone animation comprised of the bone name and the data for each channel
(defined in the .asf file) of that bone. The frame sections in the file continue until the
end of the file[11]. A snapshot of a small portion of AMC file is in Figure 1.4.
This thesis concentrates on indexing of motion data which is one of the issues
related to motion-based animation. The chapter 1 of this thesis describes motion in-
dexing, motion representation, and motion file formats. The chapter 2 describes the
two different PCA-based techniques for motion indexing and also explains them from
an implementation point of view. The chapter 3 describes the idea and implementa-
tion details of a geometric feature-based motion indexing technique. Dynamic time
warping based indexing techniques are described in the chapter 4. The chapter 5 of
the thesis describes the two types of performance evaluation: Time performance and
