what exactly is it that you don't understand? the "weighted" elements take the luminance of the blobs and interpret them as 'mass': this mans, the brighter a pixel in the blob gets, the more important it is. "centerX(weighted)" is the X coordinate of the centre of gravity, "size(weighted)" is he total 'weight' of the blob, the 'unweighted' elements, are mere 2D geometric properties, "minY" is the minimum Y coordinate of the blob, and "area" is a (normalized) count of all pixels covered by a blob. > I know [pix_multiblob] makes a matrix to get the results, but I > don't know how does that work neither. a matrix is a 2D array of N*M elements to store numbers. N is the number of rows in the array, in our case the number of detected blobs. M is the number of columns in the array, in our case 8 (centerX(weighted)...area) the iemmatrix library deals with these arrays (if you don't want to parse the simple message yourself) fgmasdr IOhannes -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk6AJ7QACgkQkX2Xpv6ydvQtYQCfeoFHcxTdI0796kk0XrG6NxB/ 8eEAoNlqXH9vGlJJ8m5AeC4CKB+Jclmb =ti55 -----END PGP SIGNATURE-----
