Abstract: Method and apparatus for analyzing an orientation of a subject. An image of an area that includes a subject to be monitored is captured, so that a model can be produced. A consistency test is then performed on the produced model to determine predetermined features of the subject. In response to a predetermined result of the consistency test, an undesired orientation of the subject is indicated.

Abstract: An apparatus and method for determining a characteristic of a selected skin lesion. A capture device produces data representing an image of an object. A processing device processes the data to derive a three-dimensional model of the skin lesion, which is stored in a database. A reporting device indicates at least one specific property of the selected skin lesion. The processing device determines a change in at least one specific property of the skin lesion by comparing the three-dimensional model with at least one previously derived three-dimensional model that is stored in the database.
