Large diaphyseal bone defects often are reconstructed with large structural allografts but these are prone to major complications. We therefore asked whether impacted morselized bone graft could be an alternative for a massive structural graft in reconstructing large diaphyseal bone defects. Defects in the femora of goats were reconstructed using a cage filled with firmly impacted morselized al...

In this report, we present a 3D building reconstruction method based on a structural approach. It consists in reconstructing buildings by assembling simple urban structures extracted from a grammar of 3D parametric models. This method is composed of two stages. The rst one, which has already been tackled in previous works, consists in extracting the building footprints through con gurations of ...

This paper presents and develops an integrated system for 3D object reconstruction and recognition, which contains three key functional subsystems: superquadric based structural description extraction, multipart object reconstruction and 3D object recognition. These three subsystems are relatively independent and also connected each other, which accomplish the conversion from 3D object data to ...

background: massive bone allograft is an option in cases of limb preservation and reconstruction after massive benign and malignant bone tumor resection. the purpose of this study was to analyze the outcome of these procedures at imam reza hospital, mashhad university of medical sciences. methods: in this study, 113 cases have been presented. eleven cases were excluded (patients has a traumatic...

A successive structural analysis using wavelet transform is proposed to remove the blocking artifacts associated with block-based coding techniques such as JPEG. The successive structural analysis is based on a study of the magnitude of the wavelet coe$cients using a set of threshold values. This allows the structural information in an image and the information about the block boundaries to be ...
