Summary
Building on the scipy.interp1d function, we have implemented a collection of curve filters that are efficient (due to the use of lookup arrays) and easily extensible (due to an object-oriented design). Our work has included special-purpose curve filters that can make digital images look more like film shots. These filters can be readily integrated into an application such as Cameo, as demonstrated by the use of our Portra film emulation filter in Chapter 3, Processing Images with OpenCV.
