Final Project on MFC 201401 Outline u Project

計算攝影學 Final Project 影像縮放內插法 on MFC介面 2014/01

Outline u. Project 說明 u最近相鄰內插法(nearest-neighbor interpolation) u立方內插法(cubic interpolation) u線性內插法(linear interpolation) u. MFC介面簡介 u速度分析比較 u. DEMO u應用 page 2

結果比較 1 -D linear interpolation(線性內插法)

結果比較 1 -D cubic interpolation(立方內插法) 1 -D cubic interpolation影像較圓滑，鋸齒狀沒那麼明顯

結果比較 nearest-neighbor interpolation(鄰近內插法)

結果比較 cubic linearest

應用The Laplacian Pyramid as a Compact Image Code u The encoding process is equivalent to sampling the image with Laplacian operators of many scales. u Thus, the code tends to enhance salient image features.

應用The Laplacian Pyramid as a Compact Image Code 可以簡化影像融合時的運 算，只須對金字塔中每一 層的資訊利用簡單的混和 係數進行縫合，就可以經 由重建過程中使用的濾波 器擴大效應 P. Burt and T. Adelson. The Laplacian Pyramid as a Compact Image Code. IEEE Transactions on Communication, COM-31: 532– 540, 1983. page 21

應用 加快運算時間 如: Laplacian Pyramid Ref: 1983_IEEE_The Laplacian Pyramid as a Compact Image Code 影像品質提升 如: Bilsteral Grid Ref: 2007_ACM_Real-time Edge-Aware Image Processing with the Bilateral Grid 影像細節保留 Ref : 2007_ACM_Detail preserving shape deformation in image editing
