Separating foreground objects from natural images and video plays
an important role in image and video editing tasks. Despite
extensive study in the last two decades, this problem still remains
challenging. In particular, extracting a foreground object in a
static image involves determining both full and partial pixel
coverage, also known as extracting a matte, which is a severely
under-constrained problem. Segmenting spatio-temporal video objects
from a video sequence is even harder since extracted foregrounds on
adjacent frames must be both spatially and temporally coherent.
Previous approaches usually require a large amount of user input
and still suffer from inaccurate results and low computational
efficiency. This book demonstrates efficient and accurate
foreground extraction methods and systems by combining advanced
computational algorithms with novel user interfaces. Our systems
are capable of extracting high quality foreground objects from
images and video with a limited amount of user input such as a few
paint strokes of the mouse. We also demonstrate a variety of
applications with the extracted foreground objects.
