Seeing the Forest For the Trees

swframe writes "A new object recognition system developed at MIT and UCLA looks for rudimentary visual features shared by multiple examples of the same object. Then it looks for combinations of those features shared by multiple examples, and combinations of those combinations, and so on, until it has assembled a model of the object that resembles a line drawing. Popular Science has a summary of the research. I've been working on something similar and I think this accomplishment looks very promising."

  1. This is a realization of David Marr's early work. by bezenek · · Score: 4, Interesting

    David Marr proposed the idea of a primal sketch as the first stage of converting the two-dimensional image on the retina to a full understanding of what is being looked at. This work culminated in a paper published in 1980 called "Theory of edge detection."

    Marr was a faculty member at MIT, so it is appropriate for this work to have been done there.

  2. While you chaps theorise by Rogerborg · · Score: 4, Interesting

    Honda just gets on with implementing it. Oh, look, it's even got an automobile analogy: Asimo just did a drive-by on your research.

  3. dogs etc by jrraines · · Score: 4, Interesting

    I certainly haven't worked in this area but for years have wondered how people including fairly young children recognize a dachshund, a bulldog and a great dane as dogs and other things as goats, cats, etc. Dogs are amazingly varied in shape and size and color. It seems like a VERY hard problem.
