Abstract
This paper analyzes a new high dynamic range infrared image enhancement algorithm, based on a guided image filter with hierarchical techniques. This algorithm adopts a base component and a detail component extracted by the guided image filter, and the two components are compressed through gamma transform to fit the dynamic display range, and then recombined to obtain the output enhancement image. Independence from the filter radius and the image gray value range increases the execution efficiency and calculation speed of the guided filter technique. In addition, guided filter is a local linear model with better edge-keeping, which allows it to avoid in curring gradient flip and causing "pseudo edge" on the edge of the image, where the gray-level change is dramatic, unlike other filters. The experiments described in this paper show that image enhancement using this algorithm results in strong detail enhancement and better visual performance, regardless of subjective(human eyes) or objective evaluation. Moreover, this algorithm also has the potential for use in real-time processing.关键词
