429 (comment
430 ok here's the plan--
432 "genesis/language"
433 raw text -> START -> representations/memory -> story tree
435 "genesis/vision"
436 raw video -> blob detector -> representations/memory -> event/structure tree
438 first, we start off with a video.
439 the video get's passed through the blob detector.
441 (blob-detector
442 first-pass- divide up each frame into exasutive polygons. no temporal dependence
443 second-pass- do a pairwise comparison of frames to link the polygons from each frame.
444 polygons can either split apart or merge, but this step establishes their geneology.
445 third-pass- link the polygons together into higher objects using hueristic rules about motion
446 these rules are determined by the language system, but for now they will be hardcoded.
447 the only thing for now is that things that move together are the same object.
448 )
451 so now, we have a temporal history of polygons.
452 the language part of the story may specify that certain characters
453 with certain qualities do certain actions.
455 "Bob is wearing a red shirt. Shirts are big. Bob is a person.
456 Mary is wearing a green shirt.
457 Bob is person-sized.
458 Bob is moving.
459 The green object is a ball.
460 Bob gives the ball to Mary."
462 Now, Genesis can select just the polygons that are important to the story,
463 and it also learns important facts such as the relative size of a person to a ball.
465 The details which are captured in the polygon-transition space are--
466 x (location of the center of each polygon), dx/dt , ((d^2)x)/(dt)^2, color (average), [left|right], polygon area
467 polygon shape
469 This information recurses on every component polygon as well.
471 When genesis want's to learn about verbs in particular,
472 it selects the aproapiate blobs from the linguistic desctiption (in bob's
473 case it's "the big red blob on the left", for example.)
475 after selecting a subset of the blobs, it calculates the angles and distances between
476 those blobs' centers as erll as whether they are touching or overlaping.
478 From this sequence it derives an example of the verb.
480 From other examples it can do arch earning to refine the sequence to its salient features.
