A system for diagnosing an object that includes a preset of an object, a visual representation associated with one or more sub objects of at least part of the object, and a module to analyze the applicable visual representation. The visual representation is captured by a device and provides a specified status of the object. Further the analysis provides a measure of fit between the preset and the specified status of the object as captured and is carried out based on keypoint descriptors used to separate sub objects on the applicable visual representation. The device has a reproduction capturing device and data connectivity.
