影像合成的目的是將多張相同場景的影像之資訊合併。影像合成的結果是一張新影像,這張新影像更合適於人或機器感知、或用來進行更進一步的影像處理作業。在這篇論文中,我們提出了一個新的方法來合成兩張失焦部分有部分重疊的照片,讓合成出來的圖片在失焦重疊的部分能有更好的視覺效果。這個新方法是使用離散小波轉換來進行合成並找出失焦重疊的部份,再使用兩階段的動態規劃演算法進行像素配對,最後根據配對的結果,我們利用內插法來修補重疊部分的灰階值,以達到更好的視覺效果。
The objective of image fusion is to combine information from multiple images of the same scene. The result of image fusion is a new image which is more suitable for human and machine perception or further image-processing tasks. In this paper, we propose a new method to fuse two out-of-focus images where the out-of-focus area are overlapped that the fused image has the better human visual effect. This method first fuses two out-of-focus images and locates the overlapped out-of-focus area, then it matches pixels by using two level dynamic matching algorithm, and finally we reconstruct the graylevel values of pixels in overlapped out-of-focus area by interpolation method for better human visual effect.
