当我们在户外拍照时，经常会出现意想不到的雨纹以及亮区和暗区的像素曝光不足/过度。为了解决这些问题，我们针对不同曝光时间拍摄的图像序列引入了一种基于多尺度图像分解的新混合方法。具体来说，混合曝光不足/过度曝光的图像以扩展小波域中像素的动态范围，同时消除雨纹。
When we take a photograph in outdoors, which is often having unexpected rain streaks and under-/over-exposed pixels in bright and dark regions. To address these problems, we introduce a new blending method based on multi-scale image decomposition for an image sequence taken with varying exposure time. Specifically, under-/over-exposed images are blended for extending the dynamic range of pixels in the wavelet domain, while removing rain streaks.
