You can construct an aspect graph by making each aspect a node in the graph and connect neighboring aspects with edges. 1.4 Problems with multiple views approach While the multiple views approach is sound in theory, this idea does not work well in practice due to too many aspects that are needed. Another problem with this method occurs because of bad segmentation. The line drawing is then matched with different aspects for recognition. This method relies on segmentation, which is not too good right now.
People recognize objects easier in familiar views.
For example, people can recognize horses easier from the side view or the front view but it is harder for people to recognize the horse from a top or bottom view. For example, in the figure below, in general it would be a straight line but there is an accidental view where it could be a circle that is viewed from the side. Similarity among visually perceived forms Eric Goldmeier studied how people judge shapes to be similar back in the 1930s and hypothesis that two shapes are more similar if their feature vectors are more similar. This meant proportional changes of parts of a figure results in a more similar figure. In the example below, people pick the graph to the right to be more similar to the original image, which contradicts the hypothesis.
