(2) Grayscale symbiosis matrix<br>Cov grayscale symbiotic matrix (GL CM) npaj siab ua Haralick assumes tias tus duab muaj 2,56 sib grayscale, thiab nug xub ua ib matrix nrog 256 (i) txhua thiab (j) 256 natwm. Nyob hauv matrix yog tus zaus cov pixels muaj grayscale kuv thiab j ib li siab xav meej hab xaav tau, thiab feem ntau cov xaav yog mus 1, nrog rau qhia mas 0, 45, 90 thiab 1 35 degrees, uas ua rau muaj plaub matrices. Tom qab ntawd, tus yam ntxwv tshwm ntawm txhua matrix payment, thiab ces tus coj tshwj xeeb txhais cov lus qhia tseem ceeb plaub yog payment. Muaj ntau tus tshiab feature extraction txoj kev yog tam sim no nyob rau GL CM, thiab cov ntsiab teeb meem nrog tus GL CM txujci no yuav teev cov xaav qhov luaj li cas. Piv txwv li, rau ib tug duab los ntawm ib qho me me n-me me, lub xaav yuav tsum noj 1 thiab n, thiab yog hais tias koj tau siv tas nrho lub displacements, coob tus nta cov generated. Tam sim no, cov soj ntsuam ntawm neej ntawd mus 1.
