Jawaabaha iyo sharraxaadaha waxay soo baxayaan markaad qaadanayso kediska.

  1. Waa maxay tirada qaladka ee ka hooseeya xisaabinta caadiga ah ee PSNR?
    • Macnaha qalad pixel sax ah
    • Cilada pixel ugu badnaan
    • Ciladda pixel-ka ee dhexdhexaadka ah
    • Jajabka pixels ee u dhigma sida saxda ah
  2. Muxuu PSNR-ga sare ku muujinayaa isla heshiiska baaxadda xogta?
    • Heshiis qoraaleedka sare
    • Khaladka dib u dhiska ee labajibaaran yahay celceliska hoose
    • Ogaanshaha shay aad u sax ah
    • Midabaynta midabada ka wanaagsan xaaladaha oo dhan
  3. Waa kuwee guryaha maxaliga ah ee ay SSIM barbardhigto?
    • Kaliya qiimaha pixel celceliska caalamiga ah
    • Kaliya farqi labajibaaran oo madax banaan oo pixel kasta ah
    • Kaliya isku-duwayaasha cidhifyada joomatari
    • Iftiinka, isbarbardhigga iyo qaab-dhismeedka
  4. Maxay tahay sababta tirada xogta PSNR ay tahay mid cad marka la barbar dhigo fulinta?
    • Its peak value depends on the image representation
    • It determines the SSIM window size
    • It removes spatial alignment needs
    • It decides which image is the reference
  5. Why can a shifted edge reduce PSNR even when it looks visually similar?
    • Matching resolution makes spatial alignment irrelevant
    • PSNR automatically corrects every spatial offset
    • Pixelwise differences penalize misalignment
    • PSNR compares object identity without considering pixel positions
  6. Does a high SSIM guarantee that an image is useful for a specific task?
    • Yes; SSIM validates every downstream decision
    • No; task-specific details may still be lost
    • Yes, if the image is grayscale
    • No; SSIM has no numerical meaning
  7. Maxay tahay in si joogto ah loo qabto marka la barbardhigo PSNR/SSIM cadaalad ah?
    • Isticmaalka isla xallinta magac ahaan waa ku filan xitaa haddii sawiradu ay khaldan yihiin
    • Isticmaalka qaab fayl isku mid ah waxay hagaajinaysaa kala duwanaanshaha kala duwanaanshaha firfircoon
    • Celceliska buundooyinka sawirkiiba iyo in ka badan pixels ayaa had iyo jeer bixiya natiijooyin isku mid ah
    • Toosinta, kala duwanaanta, dalagga, midabka maaraynta iyo isu geynta
  8. Maxay PSNR ka warbixisaa marka celceliska khaladka labajibaaran yahay eber hoos yimaado qaacidadeeda ku habboon?
    • Qiimo aan xad lahayn
    • Eber
    • Dhab ahaan hal decibel
    • Qiimaha la mid ah xoojinta pixel-ka ugu sarreeya sawirka
