Pfupiso
Pasina iyo, ma detectors anoshuma motokari imwe chete kashanu kana gumi.
Kudzika Kwakadzika
Ma detectors echinhu anowanzo kufanotaura mabhokisi akawanda evamiriri akatenderedza chinhu chimwe nechimwe chaicho, rimwe nerimwe riine zvibodzwa zvekuvimba. NMS inochekerera iyi redundancy. Iyo yakasarudzika yekukara algorithm inoronga ese mabhokisi nezvibodzwa, inochengeta yepamusoro-zvibodzwa, yobva yabvisa chero bhokisi rasara iro rinopindirana naro (rinoyerwa neIntersection over Union, IoU) rinodarika chikumbaridzo chakaita se0.5. Inodzokorora izvi pamabhokisi asara kusvika pasisina anosara. Mhedzisiro ibhokisi rinomiririra rimwe pachinhu. NMS iri nyore, inokurumidza, uye parameter-mwenje, asi ine kushaya simba: yakatarwa IoU chikumbaridzo chinogona kudzvanya zvisizvo chinhu chaicho chiri padyo munzvimbo dzakazara vanhu, uye inobata kupindirana sebhinari. Variants seSoft-NMS decay scores pane kudzima mabhokisi zvachose kugadzirisa izvi.

Ramangwana reKusanyanya Kudzvinyirira
NMS inoramba iri yakasarudzika post-processor, asi munda uri kufamba wakananga kuibvisa. Yakapfava-NMS, DIoU-NMS, uye akasiyana akadzidza anovandudza kubata-kwenzvimbo, nepo magumo-kusvika-kumagumo madetector seDETR anoshandisa set-based bipartite matching kufanotaura akasiyana mabhokisi zvakananga, kubvisa NMS zvachose. Tarisira kuti zvikumbaridzo zvakagadziridzwa nemaoko kuti zvipe nzira yekudzidza kana NMS-yemahara madhizaini, kunyanya sezvo transformer detector yakakura uye chaiyo-nguva masisitimu anoda deterministic, bazi-isina post-processing.
Kuzvishandisa
Nei zvichikosha
- Kumhanya uye chiyero. Visual AI inogona kuita otomatiki yekuongorora, yekuona, uye yekumaka mabasa pachiyero.
- Vaka sarudzo. Zvikwata zvekugadzira zvinogona prototype pfungwa nekukurumidza nekudzokororwa kwemaoko mashoma.
- Team uye workflow. Mashandisirwo anogona kushandisa masaini emifananidzo nemavhidhiyo ayo aimbove akaoma kugadzirisa.
Chenjera
- Kodzero dzemifananidzo uye kubvumirwa kunogona kuve njodzi dzepamutemo kana provenance isina kujeka.
- Kuita kwemuenzaniso kunogona kusiyanisa kupenya, huwandu hwevanhu, uye nharaunda.
- Manyepo enhema anogona kusacherechedzwa kunze kwekunge zvikumbaridzo zvekuvimba zvikatariswa.
Matanho anotevera
- Tsanangura maitiro ekugamuchirwa echokwadi, kurangarira, uye mutengo wekukanganisa.
- Edzai nedata rinoenderana nemamiriro chaiwo ekugadzira.
- Wedzera ongororo yemunhu kune yakaderera-kusavimbika kana yakakwirira-inokanganisa kufanotaura.
- Tevera modhi kudonha uye simbisa mushure mekuchinja kwekamera kana dataset.

Chii chinonzi Non-Maximum Suppression?
Non-Maximum Suppression (NMS) inhanho yekuchenesa inoshandura murwi wakashata wemabhokisi ekuona anoputika kuita bhokisi rimwechete rakatsvinda pachinhu chimwe nechimwe. Pasina iyo, ma detectors anoshuma motokari imwe chete kashanu kana gumi.
Chii chinangwa chikuru cheNon-Maximum Suppression mukuonekwa kwechinhu?
NMS inobvisa akawanda anopindirana mabhokisi emumiriri anogadzirwa ne detector, ichisiya bhokisi remumiriri pachinhu chimwe chete.
Ndeipi metric inoshandiswa neNMS yakajairwa kusarudza kana mabhokisi maviri akawandisa?
NMS matanho anopindirana neIoU: nzvimbo yemharadzano yakakamurwa nenzvimbo yemubatanidzwa yemabhokisi maviri.
MuNMS ine makaro, bhokisi ripi rinosarudzwa kutanga muround rega rega?
Inokara NMS inoronga mabhokisi nekuvimba uye inochengeta iyo yepamusoro-zvibodzwa, yobva yadzvanya anopindirana mabhokisi ane zvibodzwa zvakaderera.
Chii chinonzi kushaya simba kunozivikanwa kweNMS ine makaro munzvimbo dzakazara vanhu?
Nekuti inobvisa chero bhokisi riri pamusoro peiyo IoU chikumbaridzo, NMS inogona zvisirizvo kubvisa kutariswa kwechokwadi kwechinhu chakasiyana chinoitika kupindirana.
Ko Soft-NMS yakasiyana sei neNMS yakajairwa?
Soft-NMS inodzikisa (kuora) kuvimba kwemabhokisi anoputika pane kuirasa, kuderedza kudzvanyirirwa kwenhema munzvimbo dzakazara vanhu.
