shading effect, we proposed three searching algorithms to solve the problems. Using
this method, we hope that the segmented result will not be influenced by the back-
ground with similar color. With adaptively updating eigen-subspaces according to
the search routes, the proposed method can obtain a distinct object. The three search
algorithms will be described as follows. The square spiral search (SSS) algorithm is
showninFig. 2.11 . The four quadrant search (FQS) algorithm is shown in Fig. 2.12 .
The slant horizontal vertical search (SHVS) algorithm is shown in Fig. 2.13 .The
