Visual Interpolation and Partially Occluded Nude

The human brain evolves to perform visual interpolation, visual extrapolation, and visual completion.


The image on the right depicts an Assam tiger occluded in the Kaziranga National Park, India. When confronted with such a situation in the wild, the human brain must be able compute with the electrical signals transmitted by the photosensors in the eyes, distinguish between different shades of yellow and brown colors, interpolate between the color shades, isolate unimportant information (i.e. grass), and generate a group of electrical signals to represent the predator. When these signals are relayed to the amygdala, the emotional CPU of the brain, a "run" signal will be generated and get cascaded to motor control CPU of the brain.

A human brain which failed to perform the above visual interpolation is bound to become the lunch of another species. So, our brain has the natural tendency to do interpolation and enjoy doing so.

Now, let's turn our attention to the image on the left, which depicts a Chinese model named Zhou Weitong (周韦彤). In this photo, she was captured by a skillful photographer in a natural pose, in which the areola regions were occluded by her arm and hair. This can provide a visual stimulus for the brain to happily perform the visual interpolation and visual completion for the areola regions, and explains why a partially occluded nude is more seductive than a complete nude.
