“…Depth-map is typically made of smooth regions separated by sharp transitions along the boundaries between different objects [28]. Therefore, existing semi-automatic methods require that user scribbles do not cross object boundaries; otherwise, the quality of produced depth degrades significantly.…”

Semi-automatic 2D-to-3D conversion provides a cost-effective solution to the problem of 3D content shortage. The performance of most methods degrades significantly when cross-boundary scribbles are present due to their inability to remove unwanted input. To address this problem, a residual-driven energy function is proposed to remove unwanted input introduced by cross-boundary scribbles while preserving expected user input. Firstly, confidence of user input is computed from residuals between the estimation and user-specified depth values, and it is applied to the data fidelity term. Secondly, the residual-driven optimization is performed to estimate dense depth from user scribbles. The procedure is repeated until a maximum number of iterations is exceeded. Input confidence based on residuals avoids the propagation of unwanted scribbles and thus enables to generate high-quality depth even with cross-boundary input. Experimental results demonstrate that the proposed method removes unwanted scribbles successfully while preserving expected input, and it outperforms the state-of-the-art when presented with cross-boundary scribbles.
