In orde. to e.fe.tive.y make.biological image.classification and ide.tification, this pape. studie. the.biological owne. characte.istics, give. an e.cryption algorithm, and pre.e.ts a biological classification algorithm base. on the.e.cryption proce.s. Through studying the.composition characte.istics of palm, this pape. use. the.biological classification algorithm to carry out the.classification or re.ognition of palm, improve. the.accuracy and e.ficie.cy of the.e.isting biological classification and re.ognition approache., and compare. it with e.isting main approache. of palm classification by e.pe.ime.ts. e.pe.ime.tal re.ults show that this classification approach has the.be.te. classification e.fe.t, the.faste. computing spe.d and the.highe. classification rate.which is improve. ave.age.y by 1.46% than those.of the.main classification approache..
