我们重新审视传统图像合成技术背后的假设。通过分析过程,我们将颜色操作与覆盖操作分开,并表明这有效地导致了比以前使用的更通用的合成方程。然后,我们更详细地检查颜色操作,并展示如何将新操作轻松地纳入标准合成器中。实际的例子展示了新的方法,并揭示了一些有益的效果,而不是以前在一个合成器中实现。
We revisit the assumptions behind traditional image compositing techniques. By analysing the process we separate the colour operations from those for coverage and show that this usefully leads to a more general compositing equation than previously used. We then examine the colour operations in more detail and show how new operations can easily be incorporated in a standard compositor. Practical examples show the new approach and reveal some beneficial effects, not previously achievable within a compositor.
