Given a few training image of the same target object (same object, but may be viewed from different angles or position), the goal of object recognition is to retrieve the same object in other unseen images. It is a difficult problem because the target object in unseen image may appear different from what it appears in the training image, due to the variation of view points, background clutter, ambient illumination, partially occluded by other object or deformation of the object itself. A good object recognition algorithm is supposed to be able to recognize target object given all of the above variations.
