Câu đố về trường bức xạ thần kinh

Câu trả lời và giải thích xuất hiện khi bạn làm bài kiểm tra.

1. Which task does the original NeRF representation support from its posed scene images?
   • A guarantee of complete hidden geometry from any two photos
   • Synthesis of views not identical to the training cameras
   • Translation of every scene into a text caption
   • Mandatory face identification for every image
2. Which quantities are predicted by the original NeRF field for queried scene coordinates?
   • RGB appearance and volume density
   • Only one complete final image returned by every point query
   • The camera’s required GPS address
   • Only the training image filename
3. What does the conceptual five-dimensional input in the original NeRF paper combine?
   • Five separate input photographs
   • Five independent color channels
   • One date and four document labels
   • A 3D position and a viewing direction with two angular degrees of freedom
4. How does original NeRF rendering use queried samples along a camera ray?
   • It takes only the brightest sample regardless of every other contribution
   • It ignores sample distances and every density value
   • It composites density and color with sample distances and transmittance
   • It selects an unchanged training image solely by filename
5. What purpose does positional encoding serve in the original NeRF experiments?
   • Helping the MLP represent high-frequency coordinate-dependent detail
   • Guaranteeing a complete scene from no observations
   • Changing all spatial coordinates into camera GPS readings
   • Eliminating every optimization step
6. Hạn chế thực tế chính của NeRF ban đầu là gì?
   • Nó chỉ có thể xuất âm thanh
   • Quá trình đào tạo và kết xuất từng cảnh diễn ra chậm
   • Nó không yêu cầu ảnh nào cả
   • Nó chỉ hoạt động trong nhà
7. Which camera information is supplied with images in the stated original NeRF training setup?
   • Only a universal claim that all photo collections share one pose
   • Only a text prompt with no image-camera information
   • Known camera poses
   • A required list of real-world product prices
8. In the original NeRF architecture, how is density’s dependence on input coordinates restricted relative to color?
   • Density must depend only on viewing direction and ignore position
   • Both outputs must be constant across all positions
   • Color must ignore both position and direction
   • Density uses position only; color can also use viewing direction
