An Extraction and Composing Method for Moving Image Synthesis.
Seiki Inoue, Koyama Hiroki · The Journal of The Institute of Image Information and Television Engineers · 1993
We have already proposed an object extraction method for still images which can automatically extract an object after it is roughly specified.This paper proposes a new method which is based on the still extraction method.Based on only the input of rough boundary lines for the first two fields, this new method can automatically extract an object from moving images by conducting object extraction of the field image and generating the next rough boundary.To generate the next rough boundary the moving vectors between the two previous objects are used.The next boundary line is predicted using a vector of the whole region and expanding it to a rough boundary line using the vectors of the boundary pixels.This improves the accuracy of extraction.This paper also describes applications to objects with changing topological features.Moreover, a new soft-key technique for natural synthesis is also proposed.It can make a soft key by considering local edge strength and moving vectors.1.
