Jawaabaha iyo sharraxaadaha waxay soo baxayaan markaad qaadanayso kediska.

  1. Muxuu luminta L2-ku-saleysan pixel-ku inta badan u xukmiyaa isu ekaanshaha sawirka marka la barbar dhigo luminta garashada?
    • Waxay ciqaabaysaa isbeddellada yaryar iyo isbeddellada qaab-dhismeedka bini'aadamku si dhib yar ayay u ogaadaan
    • Si tartiib ah ayey u socotaa si ay u noqoto mid la taaban karo
    • Waxay is barbar dhigi kartaa oo kaliya sawirada cawl
    • Waxay u baahan tahay shabakad horay loo tababaray si loo xisaabiyo
  2. Muxuu LPIPS ugu horrayn is barbar dhigaya labada sawir?
    • Qiimaha pixel RGB ceeriin
    • Cabbirrada faylka ka dib cadaadis
    • Dhaqdhaqaaqyada lakabyada dhexe ee shabakad horay loo tababaray
    • Histograms midabka
  3. Sidee baa loo go'aamiyay miisaanka kanaalka LPIPS?
    • U deji dhammaan-kuwa si caadi ah
    • Ka soo horjeedda xukunnada la mid ah aragtida aadanaha
    • Gacma-hagaajinta qorayaashu
    • Ka soo jeeda miisaska cadaadiska JPEG
  4. What does a lower LPIPS value indicate for a tested image pair?
    • Proof that the two images have identical pixels
    • A guarantee that every human will prefer the lower-scoring image
    • A measurement of the images' compressed file size
    • A smaller distance under the chosen learned perceptual metric
  5. Shabakaddee laf dhabarta ayaa inta badan la xiriirta luminta garashada caadiga ah?
    • ResNet-152
    • YOLO
    • VGG
    • U-Net
  6. Hawshee sida tooska ah uga faa'iidaysanaysa isticmaalka luminta garashada halkii L2 saafi ah?
    • Sawir-dhab ah oo heer sare ah
    • Tirinta pixels ee sawirka
    • Akhrinta xogta badan ee EXIF ​​
    • Ku kala soocida sawirada magaca faylka
  7. What image-input convention does the official LPIPS Python example specify?
    • Raw compressed JPEG bytes used directly as feature maps
    • Only filename strings with no decoded image data
    • A single grayscale class label for each image
    • RGB tensors with image values scaled to the range minus one to plus one
  8. Which differences receive learned per-channel weighting inside LPIPS?
    • Differences between the images' filename lengths
    • Squared differences between normalized deep feature representations
    • Only differences between JPEG quality settings
    • Only the number of object class labels predicted
