Perspective (graphical)

Perspective (from Latin perspicere, to see through) in the graphic arts, such as drawing, is an approximate representation, on a flat surface (such as paper), of an image as it is seen by the eye. The two most characteristic features of perspective are that objects are drawn:
  • Smaller as their distance from the observer increases
  • Foreshortened: the size of an object's dimensions along the line of sight are relatively shorter than dimensions across the line of sight

Perspective (geometry)

A diagram of perspective triangles
In geometry, two triangles are perspective (or homologic) if, when the sides of each triangle are extended, they meet at three collinear points. The line which goes through the three points is known as the perspectrix, perspective axis, homology axis, or axis of perspectivity. The triangles are said to be perspective from the line.[1] The point at which the lines joining the vertices of the perspective triangle intersect is called the perspector, perspective center, homology center, pole, or center of perspectivity.
Karl von Staudt introduced the notation ABC \doublebarwedge abc for the relation of triangles ABC and abc.[2]

I know that I have given up the greatest chance ever when I was an undergrad

I barely remember stuffs from my ECE 161C class..
and now I am reading his paper after almost a half decade...

Biologically inspired object tracking using center-surround saliency mechanisms

Salience (neuroscience) -From WIKI

The salience (also called saliency) of an item – be it an object, a person, a pixel, etc. – is the state or quality by which it stands out relative to its neighbors. Saliency detection is considered to be a key attentional mechanism that facilitates learning and survival by enabling organisms to focus their limited perceptual and cognitive resources on the most pertinent subset of the available sensory data.
Saliency typically arises from contrasts between items and their neighborhood, such as a red dot surrounded by white dots, a flickering message indicator of an answering machine, or a loud noise in an otherwise quiet environment. Saliency detection is often studied in the context of the visual system, but similar mechanisms operate in other sensory systems.
When attention deployment is driven by salient stimuli, it is considered to be bottom-up, memory-free, and reactive. Attention can also be guided by top-down, memory-dependent, or anticipatory mechanisms, such as when looking ahead of moving objects or sideways before crossing streets. Humans and other animals have difficulty paying attention to more than one item simultaneously, so they are faced with the challenge of continuously integrating and prioritizing different bottom-up and top-down influences

Helloooo World..?

I decided to start keeping my blog again for the research that I'll be conducting this year 2013!! Hope all things go great~
