Direct self-calibration of central catadioptric omnidirectional cameras. (Une approche directe pour l'auto-calibration des caméras catadioptriques omnidirectionnelles centrales)

Calibrating a camera means determining the geometric properties of the imaging process, i.e., the transformation that maps a three-dimensional point, expressed with respect to a reference frame, onto its two-dimensional image whose coordinates are expressed in pixel units. This process is required when recovering 3D information. More precisely, we have to know the translation and rotation of th...

Congenital short tendo calcaneus.

It is common to see children who walk on their toes, and many different diseases are found to be the cause of this. During the past eight years we have recognised that some children, who appear to be otherwise normal, have a contracture of the calf muscles. We have not read of this condition in the literature and we call it congenital short tendo calcaneus. Between 1958 and 1964 twenty patients...

Fractures of the calcaneus

Objectives 1. Describe the anatomy of the calcaneus; including the articular facets and their orientation, the sustentaculum tali, and the apophysis 2. Describe the ossification of the calcaneus, and differences between the immature and adult calcaneus 3. Describe a classification system of calcaneal fractures useful for assessing such fractures in the immature foot 4. Discuss the imaging of a ...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2013009954 DESCRIPTION A 22-year-old man was presented to our orthopaedic clinic with right ankle pain after an inversion injury. On physical examination, there was no swelling and range of motion of the ankle joint was normal. The only symptom was pain on the dorsal pa...
