為了取得最佳的特徵點,在實驗中採用了測試影像的深度值與之間的梯度大 小作為評判標準。但此方法雖然簡單易懂,但也導致仍有特徵點無法有效地形成 最佳的三角形。在演算法技術成熟的今日,我們或許可以測試其他不同的評判擷 取節點的方式,來找出一個兼顧影像品質和時間效能的演算法。

特徵點個數對於 PSNR 的整體表現有相關的現象。也就是說,三角形的切割 數目越多對於 PSNR 上的表現越好。然而,三角形的切割數目若是過於精細則與 VSRS 2.0 的結果是差不多的。所以能夠有個好的評判準則判定整體畫面切割的 三角形個數是非常重要的研究議題。

傳統的任意視點合成(FTV)的演算法架構通常都是針對空間域上的一致性提 出改善的方法[8][9][16][17][28],目前也有許多針對景深預估的演算法架構加強 了時間域上的一致性,且實驗結果有明顯的改善效果。然而,現有的場景還原技 術而言,並沒有太多演算法設計討論並改善時間域上的一致性。或許在視點合成 演算法日漸成熟的今後,能夠更好的演算法可以提出改善影像品質的新架構。
