1. A method of generating a mask for use in generating 2-D to 3-D conversion of an object within an image, said image being present as an image-set across multiple frames of said image, said method comprising: establishing, on a processor-based system, a polygon of said object within a subset of said image-set; selecting, on the processor-based system, at least one feature of said image-set; tracking all endpoints of vertices of said polygon for all frames of said multiple frames of said image-set; determining if said at least one selected feature is missing from certain frames of said multiple frames of said image-set; auto-correcting a vertex of said polygon associated with said at least one selected feature into said certain frames when said at least one selected feature is determined by the processor-based system to be missing from said certain frames; and generating a mask of said object to fit said at least one selected feature.
