根据照明、镜面反射、反射和阴影的不同，对象的图像可能会发生很大的变化。将这些附带的变化与图像的内在方面分开通常是有利的。我们描述了一种拍摄玻璃后面物体的方法，并以数字方式去除玻璃表面的反射，保持玻璃后面物体的图像完好无损。我们描述了这种方法的细节，它使用了简单的光学技术和独立分量分析，并用几个例子说明了它的有效性。
The image of an object can vary dramatically, depending on lighting, specularities, reflections, and shadows. It is often advantageous to separate these incidental variations from the intrinsic aspects of an image. We describe a method for photographing objects behind glass and digitally removing the reflections from the surface of the glass, leaving the image of the objects behind the glass intact. We describe the details of this method, which employs simple optical techniques and independent component analysis and show its efficacy with several examples.
