Communication Engineering National Central University Video-Audio Processing Laboratory 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

Communication Engineering National Central University Video-Audio Processing Laboratory 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 。

Communication Engineering National Central University Video-Audio Processing Laboratory 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.

Communication Engineering National Central University Video-Audio Processing Laboratory 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
Communication Engineering National Central University Video-Audio Processing Laboratory 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
Communication Engineering National Central University Video-Audio Processing Laboratory 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。vap-ta@vaplab.ee.ncu.edu.tw 實驗室位置: R3-306, 分機: 57969
