摘要翻译：
皮尔士梅花形投影是一个球面到正方形内部的映射。除了赤道上的四个点，它是一张共形图。这些不符合性点在照相应用中会造成显著的伪影。在本文中，我们提出了一个算法和用户界面来减轻这些伪影。此外，为了方便交互式用户界面，我们提出了一种快速计算球面图像Peirce梅花形投影的算法。然后，在某些情况下，我们推广了皮尔士梅花形投影作为更流行的赤平投影的一种可行的替代方案。

英文摘要：
  The Peirce quincuncial projection is a mapping of the surface of a sphere to the interior of a square. It is a conformal map except for four points on the equator. These points of non-conformality cause significant artifacts in photographic applications. In this paper, we propose an algorithm and user-interface to mitigate these artifacts. Moreover, in order to facilitate an interactive user-interface, we present a fast algorithm for calculating the Peirce quincuncial projection of spherical imagery. We then promote the Peirce quincuncial projection as a viable alternative to the more popular stereographic projection in some scenarios.
