Recognizing An Object Through High-level Vision
To go further than just perceiving the object is to recognize the object. Recognizing an object plays a crucial role in resolving ambiguous images, and relies heavily on memory and prior knowledge. To recognize an object, the visual system detects familiar components of it, and compares the perceptual representation of it with a representation of the object stored in memory. This can be done using various templates of an object, such as "dog" to represent dogs in general. The template method is not always successful because members of a group may significantly differ visually from each other, and may look much different if viewed from different angles. To counter the problem of viewpoint, the visual system detects familiar components of an object in 3-dimensional space. If the components of an object perceived are in the same position and orientation of an object in memory, recognition is possible. Research has shown that people that are more creative in their imagery are better able to resolve ambiguous images. This may be due to their ability to quickly identify patterns in the image. When making a mental representation of an ambiguous image, in the same way as normal images, each part is defined and then put onto the mental representation. The more complex the scene is, the longer it takes to process and add to the representation.

Famous quotes containing the words recognizing an, recognizing, object and/or vision:
“Is a democracy, such as we know it, the last improvement possible in government? Is it not possible to take a step further towards recognizing and organizing the rights of man?”
—Henry David Thoreau (1817–1862)
“A radical is one of whom people say “He goes too far.” A conservative, on the other hand, is one who “doesn’t go far enough.” Then there is the reactionary, “one who doesn’t go at all.” All these terms are more or less objectionable, wherefore we have coined the term “progressive.” I should say that a progressive is one who insists upon recognizing new facts as they present themselves—one who adjusts legislation to these new facts.”
—Woodrow Wilson (1856–1924)
“The hero is a feeling, a man seen
As if the eye was an emotion,
As if in seeing we saw our feeling
In the object seen and saved that mystic
Against the sight, the penetrating,
Pure eye.”
—Wallace Stevens (1879–1955)
“A novel is a mirror carried along a high road. At one moment it reflects to your vision the azure skies at another the mire of the puddles at your feet. And the man who carries this mirror in his pack will be accused by you of being immoral! His mirror shews [sic] the mire, and you blame the mirror! Rather blame that high road upon which the puddle lies, still more the inspector of roads who allows the water to gather and the puddle to form.”
—Stendhal [Marie Henri Beyle] (1783–1842)
