  1. VAP HW3 Suggestion 指導教授：張寶基 　研究生：鄭玉欣 音視訊處理實驗室 2006 / 10 / 24

  2. Agenda • Part 2 -- Laboratory Exercise • (2a)：Creating your Video Sequence • (2b)：Decimation and Interpolation of Video Frames in the temporal domain • (2c)：Pyramid Decomposition in Time • Part 3 -- Laboratory Write-Up • Attention

  3. Part 2 -- Laboratory Exercise (1/3) • (2a)：Creating your Video Sequence • image17：suzie40.y，image18：suzie60.y • 在適當的位置填入你的程式碼 • 請用不同的 frame rate (fps) 觀察 video sequence • 可以試著用不同的係數內插，形成新的 video sequence，並比較新舊之間的 PSNR，那一種比較好。

  4. Part 2 -- Laboratory Exercise (2/3) • (2b)：Decimation and Interpolation of Video Frames in the temporal domain • 在適當的位置填入你的程式碼 • How does the video sequence look after decimation? • How close is the reinterpolated image to the original image for both image sequences (i.e. the sequence you created and the sequence I gave you.)? Express it by PSNRs . • 何謂 PSNR ? 寫出 PSNR 的公式並解釋它.

  5. Part 2 -- Laboratory Exercise (3/3) • (2c)：Pyramid Decomposition in Time • 在 report 中說明原理 • 在適當的位置填入你的程式碼 • Describe how you would implement pyramid decomposition in the spatial domain (i.e. a 512x512 image).

  6. Part 3 -- Laboratory Write-Up • 請討論你在此作業裡看到的每種使用不同方法得到的 video sequence 有什麼不同，你得到什麼樣的結論。 • 如果你覺得程式碼無法表現出你要的結果，你也可以自己寫出自己的程式碼，讓它更完美。

  7. Attention • 作業須包含程式碼及報告兩部份，程式碼請在截止時間前 E-mail 給助教，報告請在 10/31(二) 以紙本交給助教。 • 程式碼請加入詳細的註解，範例程式只有部份解答，你還必需自行修正，當然也歡迎全部重新撰寫。 • 請務必確認 e-mail 為vap-ta@vaplab.ee.ncu.edu.tw，寄信時可設定要求讀取回條。 • 實驗室位置：R3-306, 分機：57969
