Ukutholwa kokukhubazeka kwesihlalo sevalvu yomjovo wezimoto ngokusekelwe ekuhlanganisweni kwesici(ingxenye 3)

Ngenxa yalokho, ekutholweni kwesihlalo sevalvu yomjovo, isithombe sidinga ukucindezelwa, futhi usayizi wesithombe ucutshungulwa ku-800 × 600, ngemva kokuthola idatha yesithombe esijwayelekile esihlanganisiwe, indlela yokuthuthukisa idatha isetshenziselwa ukugwema ukushoda kwedatha, futhi ikhono lemodeli elijwayelekile liyathuthukiswa. Ukuthuthukiswa kwedatha kuyingxenye ebalulekile yokuqeqesha amamodeli okufunda ajulile [3]. Ngokuvamile kunezindlela ezimbili zokwandisa idatha. Enye iwukwengeza isendlalelo sokuphazamiseka kwedatha kumodeli yenethiwekhi ukuvumela isithombe ukuthi siqeqeshwe njalo, kukhona enye indlela eqonde kakhudlwana futhi elula, amasampula ezithombe athuthukiswa ngokucubungula izithombe ngaphambi kokuqeqeshwa, sandisa isethi yedatha sisebenzisa. izindlela zokuthuthukisa isithombe njengejometri nesikhala sombala, futhi usebenzise i-HSV esikhaleni sombala, njengoba kukhonjisiwe kuMfanekiso 1.

Ukuthuthukiswa kwemodeli yesici esisheshayo se-R-CNN Kumodeli ye-algorithm esheshayo ye-R-CNN, okokuqala, udinga ukukhipha izici zesithombe sokufaka, futhi izici zokukhiphayo ezikhishiwe zingathinta ngqo umphumela wokugcina wokutholwa. Umnyombo wokutholwa kwento ukukhishwa kwesici. Inethiwekhi yokukhipha isici esivamile kumodeli ye-algorithm ye-Faster R-CNN inethiwekhi ye-VGG-16. Le modeli yenethiwekhi yaqala ukusetshenziswa ekuhlukaniseni izithombe [4], futhi ibe yinhle kakhulu ekuhlukaniseni kwe-semantic [5] kanye nokutholwa kobuhlakani [6].

Inethiwekhi yokukhipha isici kumodeli ye-algorithm esheshayo ye-R-CNN isethelwe ku-VGG-16, nakuba imodeli ye-algorithm inokusebenza okuhle ekutholeni, isebenzisa kuphela okuphumayo kwemephu yesici kusukela kusendlalelo sokugcina ekukhishweni kwesici sesithombe, ngakho kuzoba khona okunye ukulahlekelwa kanye nemephu yesici ayikwazi ukuqedelwa ngokugcwele, okuzoholela ekungalungisweni kokutholwa kwezinto ezincane okuqondiwe futhi kuthinte umphumela wokugcina wokubonwa.
