A combination of transformations can sometimes be described using a single transformation, eg when a shape is transformed by two consecutive translations, the result can be expressed as a single ...

These reflected rectangles are example of congruent shapes. When transforming a shape, either through translation, reflection or rotation, a congruent shape is produced. Enlargements create shapes ...

Abstract: Extracting rotation and translation invariant features is a difficult task for palmprint recognition. Traditional methods have difficulty in dealing with palmprint images degraded by those ...

Abstract: The inherent challenge of detecting symmetries stems from arbitrary orientations of symmetry patterns; a reflection symmetry mirrors itself against an axis with a specific orientation while ...
