Hakiki kila swali8 maswali

Majibu na maelezo huonekana unapojibu maswali.

  1. Je, mtiririko wa macho unakadiria nini?
    • Mwendo dhahiri wa saizi kati ya fremu zinazofuatana
    • Joto la rangi ya kila sura
    • Idadi ya vitu katika picha moja
    • Mtindo wa wimbi la sauti unaoambatana na video
  2. Je, dhana ya 'uthabiti wa ung'avu' inayotumika katika mtiririko wa kawaida wa macho ni upi?
    • Kila fremu lazima iwe na mwangaza sawa wa wastani
    • Sehemu inayosogea huweka takribani mwangaza sawa kwenye fremu
    • Mwangaza lazima uongezeke kwa kasi zaidi ya video
    • Video nyeusi na nyeupe pekee ndiyo inaweza kuchanganuliwa
  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. Ni programu gani inayotegemea moja kwa moja kukadiria mwendo kati ya fremu?
    • Ufafanuzi wa fremu ya video kwa mwendo laini wa polepole
    • Kukagua hati ya maandishi
    • Inapanga picha kulingana na saizi ya faili
    • Kubadilisha hotuba kuwa maandishi
  6. Ni nini shida ya 'kuziba' katika mtiririko wa macho?
    • Wakati video ina mwanga mkali sana
    • Pikseli inapofichwa au kufichuliwa, kwa hivyo hakuna ulinganifu halali kati ya fremu
    • Wakati kasi ya fremu ni ramprogrammen 30 haswa
    • Wakati video mbili zimeunganishwa pamoja
  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
