Description
picture_dependency_maps[i][j]は、jに等しいview_idを有する非アンカーピクチャが、iに等しいview_idを有する非アンカーピクチャに依存することを示す。non_anchor_picture_dependency_maps[i][j]は、anchor_picture_dependency_maps[i][i]が1に等しい場合のみ存在する。anchor_picture_dependency_maps[i][j]が存在し、0に等しい場合、non_anchor_picture_dependency_maps[i][j]は、0に等しいと推論されるものとする。
I=P*[Xw:Yw:Zw:1]
ただし、Iは、同次座標I=[λ・Ix:λ・Iy:λ]で表される。
