Ubuchwepheshe bokukhishwa kwesici somunwe esithombeni seminwe esithombeni sokulawula ukufinyelela kweminwe

Izici zeminwe ezisetshenziswa ngokusetshenziswa kwemishini yokulawula ukungena kweminwe ekuhlonzeni kweminwe kuma-pointprint poitication yizindawo, amaphuzu alodwa nemigqa, njll. Izindawo zifaka phakathi izindawo zokugcina namaphoyinti afaka amaphuzu aphezulu. Izici zeminwe ezikhishwe zisetshenziselwa ukufana kweminwe. Ubuchwepheshe obuhle kakhulu obuthintekayo ekukhishweni kwesici somunwe buka ikakhulukazi ukubalwa kokubhaliwe, ukubalwa kwemvamisa ye-Treasuection kanye nokutholwa kwe-Triangleprint, ukuthuthukiswa kweminwe, ukukhishwa kweminwe kanye nokukhishwa, ukukhishwa kwe-node. Ukubalwa njll.

Ukubalwa kokuqondiswa kokuthungwa kuyisisekelo sokukhonjwa kweminwe. Iningi lama-algorithms ekuhlonzeni kweminwe lisuselwa ekuqondisweni, njengokubala imvamisa, ukulandelela ukuthungwa, ukutholwa kwamaphoyinti aphezulu, ukuthuthukiswa kweminwe, ukuhambisana kweminwe, ukuhambisana kweminwe, njll. Iningi lama-algorithms asuselwa ekuqondisweni. Indlela yokubala ye-Teacture isuselwa ezingeni elingwevu phakathi kwamaphikseli, iqhathanisa ibhulokhi ngalinye le-2x2 ngezifanekiso ezine ezinqenqemeni ukuze zikhiphe indlela ye-pixel block, bese yenza isilinganiso esiphakathi nendawo ngokususelwa endaweni enkulu uma kunzima Ukuthola ukuqondiswa, umplali usebenzisa indlela yokuqondanisa ye-Grayscale ukubala ukuqondiswa kwe-grayscale ukubala ukuqondiswa kokuthungwa, nokuqonda ukuqondiswa kwezindlela eziyi-16, futhi kubale ukungaguquguquki kwe-grayscale yephikseli ngayinye. Thatha ukuqondiswa ngokuvumelana okuhle kakhulu njengokuqondisa kwekhaya, bese ubala ushintsho lwe-greyscale eceleni ngakunye, ushintsho olunemibala egangeni luncane kakhulu, futhi i-grayscale iguqukela eceleni okusanhlamvu okusanhlamvu ngobukhulu. Guqula kube amaphikiseli abhalwe phansi namaphikiseli angezincwadi, asuse ukuqondiswa kokubhaliwe abe yizinkomba eziyi-16, bese ubala ukuvumelana kwe-pixel yephikseli ngalinye endaweni ngayinye, sebenzisa indlela yokuqagela ukubala ukuqondiswa kokuthungwa, bese uhlukanisa isithombe somunwe ku Ubukhulu be-32n32 block, bese ubale ukuqagela kwebhulokhi ngayinye ngezindlela ezihlukile, thatha ukuqondiswa ngohlobo olukhulu lokuqagela njengokuqondisa okuthe mpo kokuthungwa, bese usebenzisa inethiwekhi ye-Hierarchical Neural ukubala inkambu yokuqondisa. Njengamanje, indlela yokubala eyayisetshenziswa kakhulu ye-Testructure yokubala isuselwa ku-gradient. Indlela imbi. Le ndlela ibala i-gradient veter yesithombe somunwe ePixel ngayinye. Ukuqondiswa kwe-gradient vector kumelela ukuguqulwa okusheshayo kwe-grayscale yesithombe somunwe ngalesi siqondiso ePixel, kanti usayizi we-gradient vector umele ijubane lokushintsha kwe-grayscale. I-pixel gradient emaphethelweni wokuthungwa esithombeni inkulu, ukuqondiswa kokuthungwa okubalwe ngale ndlela ngokuyisisekelo kunqunywa yilawo maphikseli ane-gradient enkulu, kanye nesiqondisi se-gradient yesithombe emaphethelweni ngokuyisisekelo indlela yokuqondisa. Ukuqondiswa kokuthungwa kwendawo ngayinye kususelwa kuwo wonke amadolobha akule ndawo.
I-gradient verel ye-pixel ibalwa, kanye nokuqondiswa kwe-gradient vector yekhebula lesithombe ngakwesokunxele nakwesokudla kokwehla kokuthungwa kuphambene, ukuze kugweme ukwesulwa okubonakalayo ekubalweni. Esibalweni, i-antimony degree veector isikwadi, kanye ne-squared gradient vevely yamaphikseli angakwesokunxele nakwesokudla kokwelashwa kuzokhomba ngokulingana okulinganayo, bese kuba ukuqondiswa okuphakathi kwe-squared GradientE. Ngoba ukuqondiswa kwe-squared gradient veiect kuyinto kabili le-vevector ye-squared gradient, 1 NI yesihloko esicishe sibe somaphakathi se-vetector ephansi esilinganiselwe ukuqondisa okuthe mpo kokuthungwa okuthe xaxa. Inkinga ngendlela esekwe ku-Gradient-based ukuthi lapho isiqondisi lapho isiqondisi se-gradient samaphikseli anqenqemeni singalungele ukuqondiswa kokuthungwa, indlela engalungile izobalwa njengesithombe sokuqala, okuwumphumela wokulinganisa. Kunokulinganiselwa okuningi kwenkomba engalungile endaweni yase-Elliptical, okungukukhulisa kancane kancane kwesithombe sendawo sendawo, kusuka lapho kusondeza isithombe sikazwelonke, kungabonakala ukuthi imibhalo ye-gradient yamaphikseli amaningi angeyona i-Pixels ukuqondiswa kokuthungwa, ngaleyo ndlela kuholele ekulinganiselweni kwenkomba engafanele. Indlela ingalungisa indlela engalungile yomsebenzi ohlukanisiwe, kepha lapho indlela engalungile endaweni ethile iyona iningi, hhayi kuphela umuzwa wokuqondisa okungalungile ongalungiswa. Indlela efanele izolungiswa ngokungalungile, futhi ukuqondisa eduze kwephoyinti eliyisisekelo kuzoshintsha kuvela esiqondisweni sangempela ngemuva kokuhlunga okuphansi. Lapho i-curvature yokuthungwa eduze kwephuzu eliyisisekelo inkulu.
