多視角影像的色彩校正是一項基本但具有挑戰性的任務，旨在生成顏
色一致的組合影像，並在三維影像重建中獲得更好的渲染效果具有重要應
用。在本論文中，我們提出了一種新穎且有效的多視角影像色彩校正演算
法。我們首先利用修改過的顏色差距度量 (MCD)，計算每對圖像 Vi 和 Vj
的重疊區域的殘差，並將其作為邊 (Vi, Vj) 的權重，其中 Vi 和 Vj 也被視
為兩個節點。接下來，我們提出了一種最小權重優先的方法來選擇第一個
進行顏色校正的目標影像 It。然後，我們提出了一種將直方圖均衡化和雙
邊插值法結合的方法，對 It 進行色彩校正。在此之後，更新 It 與其重疊
影像之間的權重。上述基於最小權重優先法的目標影像選擇、色彩校正和
權重更新的過程將重複進行，直到所有多視角影像的色彩校正完成。根據
大規模測試多視角影像資料集，綜合實驗結果證明了我們的演算法在定量
和定性品質方面相對於最先進色彩校正方法的優勢。

Color correction for multiview images is a fundamental but challenging task to generate a color consistent composite image, and has important
applications in rendering better 3D geometric reconstruction. In this paper,
we propose a novel effective color correction algorithm for multiview images. Using our modified color distance (MCD) metric, we first estimate
the residual of the overlapped region of each image pair, Vi and Vj, as the
weight of the edge (Vi, Vj) where Vi and Vj are also viewed as two nodes.
Next, a minimum weight-first approach is proposed to select the first target
image It to be performed for color correction. Then, we propose a fusion
based method, which integrates the histogram equalization and the joint bilateral interpolation, to correct color for It. After that, the weights between
It and its overlapped images are updated. The above minimum weightfirst based target image selection, color correction, and weight updation
process are repeated until the color correction for all multiview images is
completed. Based on large-scale testing multiview image datasets, comprehensive experimental results demonstrated the quantitative and qualitative quality merits of our algorithm relative to state-of-the-art methods.
