In this paper, the conventional goals of visual reconstruction are generalized to include both visible and occluded forward facing surfaces. This larger fraction of the environment is termed the anterior surfaces. In this paper, we show that the boundaries of the anterior surfaces can be represented in viewer-centered coordinates as a labeled knot diagram. Where boundaries are not occluded and where surface reflectance is distinct from that of the background, boundaries will be marked by image contours. However, where boundaries are occluded, or where surface reflectance matches background reflectance, there will be no detectable luminance change in the image. Deducing the complete image trace of the boundaries of the anterior surfaces under these circumstances is termed the figural completion problem. The second half of this paper describes a computational theory of figural completion. A working model is demonstrated on a variety of illusory contour displays. The experimental system employs a two stage process of completion hypothesis and combinatorial optimization. The labeling scheme is enforced by integer linear inequalities so that the optimal feasible solution of an integer linear program defines a typologically valid surface organization.<<ETX>>","PeriodicalId":160667,"journal":{"name":"1994 Proceedings of IEEE Conference on Computer Vision and Pattern Recognition","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115017184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Object modeling from a sequence of range images has been formulated as a problem of principal component analysis with missing data (PCAMD), which can be generalized as a weighted least square (WLS) minimization problem. After all visible regions appeared over the whole sequence are segmented and tracked, a normal measurement matrix of surface normals and a distance measurement matrix of normal distances to the origin are constructed respectively. These two measurement matrices, with possibly many missing elements due to occlusion and mismatching, enable us to formulate multiple view merging as a combination of two WLS problems. The solution to the first WLS problem, which employs the quaternion representation of the rotation matrix, yields surface normals and rotation matrices. Subsequently the normal distances and translation vectors are computed by solving the second WLS problem. Experiments using synthetic data and real range images show that our approach is robust against noise and mismatch because it produces a statistically optimal object model by making use of redundancy from multiple views. A toy house model from a sequence of real range images is presented.<<ETX>>","PeriodicalId":160667,"journal":{"name":"1994 Proceedings of IEEE Conference on Computer Vision and Pattern Recognition","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117115621","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The key property that orientation-based representations share is that they rotate in the same way as the object rotates. Combinations of orientation-based representations of a model and of a sensed object determine inequalities that become equalities if and only if the object and model match both in identity and in attitude. This results in optimization problems that can be solved by standard numerical methods. The paper unifies and extends previous work based on the Extended Gaussian Image (EGI) representation. It provides the theoretical basis for new approaches to object recognition and attitude determination using dense surface data. It extends results on convex polyhedra to the domain of smooth, strictly convex surfaces. The class of shapes covered also is extended to include starshaped sets. The theoretical results lead to feasible algorithms that are both accurate and robust. A proof-of-concept system has been implemented and experiments conducted both on synthesized data and on data obtained from real objects.<<ETX>>","PeriodicalId":160667,"journal":{"name":"1994 Proceedings of IEEE Conference on Computer Vision and Pattern Recognition","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115332191","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
