  3. Introduction • 動機 ─ 隨著時代的進步，大家越來越注重相片的運用，在課堂上聽到老師介紹全景照片合成，因此對此方向感興趣，作為期末的project。 • 設備平台 ─ CPU:Intel(R) Core(TM)i5-480M ─ Memory:4.00GB ─ OS:Windows 7 ─ Software:Visual C++ 2010 Professional Edition ─ Other:OpenCV、GLUI

  4. Method • 利用SIFT去找特徵點作matching • Blend image ─ LaplacianPyramid Blending 1.Build Laplacianpyramids for each image. 2.Build a Gaussian pyramid of region mask. 3.Blend each level of pyramid using region mask from the same level: 4.Collapse the pyramid to get the final blended image.

  5. Use • glui介面 ─ 在sorce1、 sorce2、 sorce3分別點選想要 的照片。 ─ 當選定好照片之後按下start，稍待片刻， 當處理完成後，會把結果儲存並且show到 銀幕上。

  6. Demo 連結 • 影片連結http://youtu.be/b4wYPllWsT8 • 測試相片 ─ 採用之前旅遊實際拍攝 ─ 解析度：3648*2736
