for each child node c of c that is not visited { s.push(c); mark c as visited; } } } However this way we lost track of the finish time. If we want to also mark the finish time, we can not pop the node out when we discovered the node. we need to keep it in the stack ...

For a picture I, the part of the portrait we are interested in is called foreground F, and the rest is background B, then image I can be regarded as a weighted fusion of F and B: I = alphaF + (1-alpha)BI= alpha∗F+(1−alpha)∗B, and the matting task is to find the...
