Marr poggio algorithmus
Webdeveloped by D. Marr and his school, zero-crossings detection is proposed as one of the first stages of human visual information processing. The justification of this theory reguires that the zero crossings are rich in information about the original image. In a paper, T. Poggio, H.K. Nishihara and K.R.K.

I979; Marr & Hildreth I980), and above that are edge segments. Zero-crossing here refers to the zero values in the convolution of the image I with a mask shaped like V2G, where V2 is the Laplacian operator, and G is a two-dimensional Gaussian distribution. These zero crossings can be thought of
WebIn the first model, Marr and Poggio performed simulations to demonstrate the effectiveness of their algorithm on random-dot stereograms, first introduced by Bela Julesz (Julesz, 1971). The elegant simplicity of the network model was anticipated in earlier research @ev, 1975; Nelson, 1975), but the interpretation of the constraints and the ... WebIndeed, a recent theory of human stereo vision (Marr and Poggio 1979, 1980; Grimson, 1981, see Marr 1982) proposes that the two images are filtered through about four independent channels, each with a different center-surround receptive field size; and that stereo-matching is based on zero- crossings-boundaries between regions of positive and ...
