| Abstract(in English) | In this paper, we propose an accurate haze reduction method that divides hazed images into regions in advance, where haze reduction processing is di?cult, and applies it to the estimation of ambient light. The conventional method has a problem that the amount of haze is estimated larger than the actual amount in the regions where the distance between the photographic spot and subject is long, and causes that ambient light cannot be estimated accurately. The region which is di?cult to process is mainly a white region and an sky region. If those regions are processed in the same way as other regions, bad e?ects are observed such as the image becomes darker or its color changes too much. In the proposed method, the regions which are di?cult to estimate the amount of haze are divided into regions by extracting pixels similar to the feature pixels, and then ambient light is determined from the regions where haze reduction processing is easy. The proposed method can easily extract the appropriate color of haze for any given image. |
