  1. Fi fun awọn fọto ti iṣẹlẹ kan, kini kolaginni wiwo aramada gbiyanju lati gbejade?
    • Lati compress awọn aworan sinu awọn faili kekere
    • Lati tumọ awọn akọle aworan si awọn ede miiran
    • Lati ṣawari awọn nkan ni fọto ẹyọkan
    • Lati ṣe iwoye kan lati awọn iwo kamẹra ti a ko gba ni akọkọ
  2. Kini aaye Radiance Neural (NeRF) ṣe maapu ipo 3D kan ati itọsọna wiwo si?

    • Nipa didakọ aworan ikẹkọ ti o sunmọ julọ taara
    • Nipa aropin gbogbo awọn piksẹli ninu dataset

  4. What distinguishes 3D Gaussian Splatting's scene representation from an original NeRF-style per-ray network evaluation?
    • Explicit 3D Gaussian primitives rendered through a differentiable rasterization approach
    • A representation containing no scene parameters or image observations
    • Only a table of audio phonemes
    • A method that copies a single input photo for every viewpoint
  5. Kini idi ti awọn ọna NVS le ṣe ẹda awọn iṣaro ati awọn ifojusi didan?
    • Wọn foju ina patapata
    • Wọn ṣe awoṣe irisi ti o gbẹkẹle, nitorinaa awọ le yipada pẹlu itọsọna wiwo
    • Wọn mu nikan ni grẹyscale
    • Wọn lo awọn ipoidojuko GPS
  6. What representation technique is central to Instant-NGP's acceleration of neural graphics tasks?
    • Removing all input observations from training
    • Converting the scene into a spreadsheet of filenames
    • A guarantee of the same training time for every scene
    • A multiresolution hash encoding
  7. What supplies the photometric training target in original NeRF scene optimization?
    • Observed pixel colors in the training images, compared with rendered colors
    • A required ground-truth 3D mesh for every scene
    • Only the scene's written caption
    • Only the final image's file size
  8. Why did original NeRF use positional encoding on its coordinate inputs?
    • To identify the camera's serial number
    • To supply surveyed coordinates without measurements
    • To help the network represent high-frequency spatial and directional variation
    • To eliminate every need for a radiance-field network
