Object recognition software needs no training
Object recognition software needs no training: "Typically, object recognition algorithms need to be 'trained' using digital images in which objects have been outlined and labeled by hand. By looking at a million pictures of cars labeled 'car,' an algorithm can learn to recognize features shared by images of cars. The problem is that for every new class of objects — trees, buildings, telephone poles — the algorithm has to be trained all over again. But Antonio Torralba and Computer Science and his colleagues at MIT have developed an object recognition system that doesn't require any training. Nonetheless, it still identifies objects with 50 percent greater accuracy than the best prior algorithm. The system uses a modified version of a so-called motion estimation algorithm, a type of algorithm common in video processing. Since consecutive frames of video usually change very little, data compression schemes often store the unchanging aspects of a scene once, updating only the positions of moving objects. The motion estimation algorithm determines which objects have moved from one frame to the next. In a video, that's usually fairly easy to do: most objects don't move very far in one-30th of a second. Nor does the algorithm need to know what the object is; it just has to recognize, say, corners and edges, and how their appearance typically changes under different perspectives.

Where to Find High Quality Industrial / Machine Vision Lenses at a Fair Price
I am often asked where to find fair pricing on quality industrial and machine vision lenses?
Industrial Vision Components sells machine vision lenses, bandpass filters, as well as sensors and other components. They have an online store with readily available pricing and free US shipping on order over $300.00. This keeps the freight bills down.
If you are looking for a Kowa Lens or Fujinon Lens here are some quick links:
