Ideal matrices and clutters are prevalent in Combinatorial Optimization, ranging from balanced matrices, clutters of T -joins, to clutters of rooted arborescences. Most of the known examples of ideal clutters are combinatorial in nature. In this paper, rendered by the recently developed theory of cuboids, we provide a different class of ideal clutters, one that is geometric in nature. The advan...

One of the main goals of computer vision has been understanding the overall scene and the various components in the scene from an image. In order to guarantee that the resulting output is valid in three dimensions, three dimensional reasoning must be done. My previous work on reconstruction of indoor building structures and detecting cuboid and rectangular objects have made use of strict three ...

Tarsal coalitions are a group of osseous anomalies where there is bridge between two or more bones that normally does not exist. This often results in decreased abnormal motion which can lead to pain and deformity over time. case report centers on 41-year-old male with rare coalition the lateral cuneiform cuboid foot was identified magnetic resonance imaging (MRI) after plain radiographs failed...

Purpose: To evaluate 2 surgical prosedures in treatment of congenital clubfeet in children younger than 24 months. Materials and Methods: Data were analyzed on 319 patients (448 feet) from July 1990 to December 2005. Clinical and classification for all patients according to Diméglio. Operated patients were divided into two groups: group 1, selective soft tissue release; and group 2, selective s...

Tarsal coalitions appear in 2% of the population, although for some the incidence of tarsal coalitions ranges from 0.03% to 0.38%1. Talonavicular and talocalcaneal coalitions are the most common symptomatic coalitions. Their presence in other tarsal joints such as talonavicular, calcaneus cuboid and naviculocuneiform joints is very rare. Leonard2, in a long series of tarsal coalitions, found th...

Missing data due to occlusion is a key challenge in 3D acquisition, particularly in cluttered man-made scenes. Such partial information about the scenes limits our ability to analyze and understand them. In this work we abstract such environments as collections of cuboids and hallucinate geometry in the occluded regions by globally analyzing the physical stability of the resultant arrangements ...
