An important contribution is made towards the overall knowledge base of automatic 2D-to-3D conversion techniques, through the collation of existing information, expansion of existing methods and development of newer concepts. Novel contributions are made in the sub-speciality fields of ROI estimation, OOI matting, LDOF image classification, Gestalt-based region categorisation, vanishing point detection, relative depth assignment and hole-filling or inpainting. Each stage of the proposed model is benchmarked against data from several significant publications. To minimising the effects of the lateral striations, specific directional Gaussian and circular averaging smoothing is applied independently to each view, with additional average filtering applied to the border transitions.

Hole-filling of the remaining dis-occlusions is performed through nearest-neighbour horizontal interpolation, which incorporates depth as well as direction of warp. To minimise some of the dis-occlusions that are generated through the 3D warping sub-process within the DIBR process the depth map is pre-smoothed using an asymmetric bilateral filter.

Depth is assigned to each of the six labels by correlating Gestalt-based principles with vanishing point estimation, gradient plane approximation and depth from defocus (DfD). Subsequently the OOI is extracted from within the ROI through analysis of the dominant gradients and edge saliencies together with k-means segmentation. Figure 4 shows a block diagram of the 2D-3D continuous conversion paradigm. Refinement of the ROI is performed using k-means segmentation and CIEDE2000 colour-difference matching. optical-ow-based depth maps and depth image-based rendering techniques, common among most 2D-3D conversion techniques, in favour of simpler methods for estimating a measure of pixel displacements between consecutive frames. This is achieved through the correlation of edge, gradient and higher-order statistics (HOS) saliencies. Initially the in focus foreground or region-of-interest (ROI) is separated from the out of focus background. The matting of the OOI is also performed in two stages. The second involves the global object and region grouping of the non-OOI regions. The first involves the delineation of the dominant object-of-interest (OOI). The objects and regions in the image are initially assigned to one of six proposed groups or labels. Subsequently the left and right disparity images are produced through depth imagebased rendering (DIBR). Initially a depth map is produced through the assignment of depth to every delineated object and region in the image.
