Abstract
Object-based technology is important
for computer vision applications including gesture
understanding, image recognition, augmented reality,
etc. However, extracting the shape information of
semantic objects from video sequences is a very
difficult task, since this information is not explicitly
provided within the video data. Therefore, an
application for exttracting the semantic video object
is indispensable and important for many advanced
applications.
An algorithm for semi-automatic video object
extraction system has been developed. The performance
measures of video object extraction system;
including evaluation using ground truth and
error metric is shown, followed by some practical
uses of our video object extraction system.
The principle at the basis of semi-automatic object
extraction technique is the interaction of the user
during some stages of the segmentation process,
whereby the semantic information is provided
directly by the user. After the user provides the initial
segmentation of the semantic video objects, a
tracking mechanism follows its temporal
transformation in the subsequent frames, thus
propagating the semantic information.
Since the tracking tends to introduce boundary
errors, the semantic information can be refreshed by
the user at certain key frame locations in the video
sequence. The tracking mechanism can also operate
in forward or backward direction of the video
sequence.
The performance analysis of the results is described
using single and multiple key frames; Mean Error
and “Last_Error”, and also forward and backward
extraction. To achieve best performance, results from
forward and backward extraction can be merged.
