摘要
该文提出了一种基于快速滤波的HDR图象对比度调整新技术。我们首先将图象分为两个层：基层和细节层（编码图象细节信息），然后保持细节层不变，对基层进行对比度调整，从而在进行对比度调整的同时较好的的保持了输入图象的细节信息。我们通过对输入图象进行滤波来获取基层。本文主要探讨了两种滤波器在新的对比度调整框架下的应用效果，并给出了详细的结果和深入的分析比较。
The paper provided a new technique to adjust the contrast of High-Dynamic-Range Images based on filtering. Our new scheme is based on a two-scale decomposition of the image into a base layer, encoding rough variations, and a detail layer. We adjust the contrast on the base layer only so as to preserve the detail. To get the base layer, we apply filtering technique on the input High-Dynamic-Range Image. We explore the effect of two different filtering techniques. Detailed results are shown and compared.
