By theanalysis of target infraredfeatures, first the three-dimension gray plane image is projected into two two-dimension images, then theedge, angle and areafeatures can beextracted respectivelybThese features are syncretized to obtain the planenull s features. The conclusion expressesthat thecomplexity of feature extraction system is simplified obviously and the circuit is easy to implementationbKey words: projection; gray image; featureextraction; parallel processing1 null„nullýHø„u×^m^¥ñ×1+˜bHø+˜^œñm^MY¥$,^˜+˜„u×+˜4|¥-4b˜+˜u×+˜4|„"STs Ë Ÿªû^×1¥b"S™8¥‚]†Ê¥ õ¤)A–™îC˜,ƒtC˜YÈ^Bñ†Ê¥ 7S)²S½, VT¹È^¥ eŐ|b'Ӑ¨1ä_/¿©M+˜4|¥±^[1],f"S+Ÿs¥$,54|çm^¥Hø+˜,–ª4|m^Ï¥‚MŸ˜+˜[2]„u×+˜,¨¯ VIñ† qCPLD ŸLCb2 nullçm^+˜4|ZE'Ó|HøZE„u×ZE²†B,n5¨ðÄ¥m^¥uא„Hø,–ªm^sé©M÷„˜Ä¥©M÷¥·/, æ¨Hø¥Ú’Ÿ„uא¥a‹Ÿ,[uא¹ö,Hø¹€ , V[4Ú+˜4|¥ZÿŸ,h"Ä bŒfƒÕ+ç¥MY`,¨¿©M¥+˜4|ZE„¿g•¥+˜4|ZE[3]!9çm^+˜4|"d,4|¨¿MYf†Ê¥çm^+˜bçm^+˜4|È^¨i›) Ø„LH) Ø¥!9±X, æ¨CPLD VIñ† q ŸLCbnull 2.1 null¿©M¥çm^+˜4|¿©M¥çm^+˜4|4Ú"d¥a‹ŸaÚ’Ÿ„ yΟ µ×1¥ilb'Óùî¥f"S^[‚]¥Î„Úf›¥bfòñ†Ê¥£“£•v‚]bÑ{΄ð{ÎÕf›Î/ç°Zm¥î„sƒûµA÷¥‚]b©¤ž¥f£“£•m^۝‚Û¥‚]7?3bv„êl¥MÄbîÿÍ  ÖL”î^H,m^öµA÷¥•wM™b"SÍu×=¤¥†–áím^ Ÿª,A¶LH4|m^¥+˜,fV"S-(m^Àµ›†¤ž-),›îf†Ê¥MY,ióIÄbyN,A¶Ê¹ƒÕáím^!9BÕ+˜4|È^bÐ.dm^+˜4|M1,'Ӑ¨v?i›) ØÈ^,‚Œ1¤žHø¥]HÉ›u×sé,_©Hø+˜„˜+˜,7OÎ1‚¥HWà|ƒtu× õ¤Ó"S¥ †m^,i4|+…™+˜„ õ¤1"báí¥ÄBHYm^û9FB,’‚¹Vm^Ï4|¥+˜@[MY"S¥Œöÿ„t†ÊH,MY"dü‚?Ãá훜ñ"S,°¤óMY²T,^ö†bnull 2.2 null¿g•¥çm^+˜4|m1nullçm^ ë8USm©¤ž£“;|ªÜVbvas),Mî¹m)çm^,Âm1îUb'Ó4BÕ¿g•¥çm^+˜4|ZE:²†áíî^¥H½Ÿ,|Ø»çm^g•žXO YÜë„YOZÜëbƒ Ú1ÿi^YOZÜë¥g•^BñáíH Yç´¥g•bg•MÐ^|Ø»çm^Ĺñ=»=´m^,YVh” ¥»” ŸržeÄ) ØVñ,£i›) Ø΄hl"d8¥"¥b5y ëçm^US",•vm1, X๝jÆáVf561nulllà°ù: 2002-01-16T€eº:”òù(1972-),o,Š28Œg¦,b¿vÐÈ0ýñ"ƒ=,pV,ö1VYÚÎm^MY„¦ýÆ?Zë¥ùîb¥áíHWà,US¹"H Y; Yà‹¿Nñ†îB†¥©í,BH Y©ž"S¥©í
