Some of the methods for retrieving digital images and videos were easier than others.

Visual imagery and information is assessed and evaluated according to multiple forms (e.g., still images, video, sequences, computer graphics, animations and stereoscopic images), which extend to multi-view devices and 3D videos. This was one of the reasons why the following websites were selected for this discussion and evaluation (Chang, Smith, Beigi, & Benitez, 1997).
