Jawaabaha iyo sharraxaadaha waxay soo baxayaan markaad qaadanayso kediska.

  1. Muxuu dhab ahaantii ku qiyaasaa socodka indhaha?
    • Dhaqdhaqaaqa muuqda ee pixels inta u dhaxaysa fiimyada isku xiga
    • Heerkulka midabka ee jir kasta
    • Tirada walxaha ku jira hal sawir
    • Qaabka mowjada maqalka ah ee la socota muqaal
  2. Waa maxay malo-awaalka 'soo-noolaanshaha joogtada' ee loo isticmaalo socodka indhaha ee caadiga ah?
    • Jir kastaa waa inuu lahaadaa dhalaal dhexdhexaad ah oo isku mid ah
    • Barta dhaqaaqa waxay ilaalinaysaa qiyaastii isla dhalaalka guud ahaan fareemada
    • Iftiinku waa inuu si joogto ah u kordhaa marka loo eego fiidiyowga
    • Fiidiyow madow iyo caddaan ah oo keliya ayaa la falanqeyn karaa
  3. Which method uses a 4D correlation volume and recurrent updates for optical flow?
    • Tesseract
    • Mask R-CNN
    • RAFT
    • Swin patch merging
  4. Why can classic optical-flow assumptions fail in fast motion?
    • Because frames contain no pixels
    • Because flow is a text-only task
    • Because all motion is uniform
    • Large displacement, occlusion, or brightness changes violate local smoothness or brightness-constancy assumptions
  5. Waa kuwee codsi si toos ah ugu tiirsan qiyaasidda dhaqdhaqaaqa u dhexeeya xayndaabyada?
    • Fiidiyowga isdhexgalka si tartiib tartiib ah u socdo
    • Higaada-hubinta dukumeenti qoraal ah
    • Ku kala soocida sawirada cabirka faylka
    • U beddelashada hadalka qoraal
  6. Waa maxay dhibaatada 'dhaqashada' socodka indhaha?
    • Marka muuqaalku aad u iftiimo
    • Marka pixel uu qarsoomo ama la muujiyo, markaa ma jiro ciyaar sax ah oo u dhaxaysa fareemada
    • Marka heerka jirku uu yahay 30fps
    • Marka laba fiidiyoow la isku daro
  7. What is the output of dense optical flow?
    • One class label for the whole clip
    • A 3D mesh with metric scale
    • A displacement vector estimate for each image pixel
    • A transcript of the audio
  8. What is one reason flow can be uncertain in a textureless region?
    • Every pixel is assigned a unique object name
    • The region has too many labels
    • Optical flow only works on text
    • There may be too little local visual information to identify a unique match
