Abstract: A method and a system for depth selective segmentation of an object are provided. The method comprises the following steps. An image is captured in an invisible domain of the optical spectrum by illuminating a scene of interest under an illumination corresponding to said invisible domain of the optical spectrum by an invisible light illumination unit. A binary mask is obtained from the image according to a threshold. Part of the image is eliminated by applying the binary mask to the image, and resulting in another image. The threshold is changed and another binary mask is obtained. The latest obtained binary mask is applied to the latest captured image. The step of changing of the threshold, the step of obtaining a mask and the step of applying the latest obtained binary mask on the latest captured image are performed at least once.

Abstract: A hole filling method for multi-view disparity maps is provided. At least one disparity map is respectively captured as a plurality of known views among a plurality of views for capturing an object. As for a plurality of virtual views among the views excluding the at least one known view, disparity maps of the virtual views are synthesized by sequentially using the disparity maps of the known views according to a distance of a virtual camera position or a transformed angle between each virtual view and each known view. Hole filling information of the disparity maps of other virtual views having the distances or the transformed angles smaller than that of the virtual view is used to fill holes in the synthesized disparity maps of the virtual views.
Abstract translation: 提供了一种用于多视角视差图的孔填充方法。 在用于捕获对象的多个视图中，分别捕获至少一个视差图作为多个已知视图。 对于除了至少一个已知视图之外的视图中的多个虚拟视图，虚拟视图的视差图是通过依照虚拟相机位置的距离或者虚拟相机位置的距离或者在 每个虚拟视图和每个已知视图。 使用具有小于虚拟视图的距离或变换角度的其他虚拟视图的视差图的填孔信息来填充虚拟视图的合成视差图中的空洞。
