Versatile high dynamic range coding for high efficient transmission

高动态范围(HDR)图像比传统图像具有更多的细节，因此有望应用于目标检测、目标跟踪或缺陷检测。然而，大多数多层HDR编码技术不能在提高准确率的同时提高编码效率，该研究提出了可逆色调映射技术来提高SIFT目标跟踪的精度。我们利用色调映射的可逆性实现了一种高效的多层HDR编码，它可以选择性地解码两种色调映射效应：用于目标检测的边缘保持平滑效应和用于目标跟踪的细节增强效应。

High dynamic range (HDR) images have more details than conventional images therefore it is expected to apply to object detection, object tracking or flaw detection. Most of multi-layer HDR coding techniques, however, cannot achieve both improving accuracy of them and high coding efficiency.This research proposed invertible tone-mapping technique which can improve the accuracy of SIFT object tracking. We achieved a high efficient multi-layer HDR coding by using invertibility of tone-mapping, and it can selectively decode two types of tone-mapping effects: edge-preserving smoothing effect for object detection and detail enhancement effect for object tracking.
