SUMMARY:

The problem of highlight removal from image data refers to an open problem in computer vision concerning the estimation of specular reflection components and the removal thereof. In recent applications, highlight removal methods have been employed for the reproduction of specular highlights on high dynamic range displays; in specular reflection control technologies to increase glossiness of images; to improve image quality in display systems such as TVs; and to enhance the dynamic range of low dynamic range images. However, the underlying processing required by state-of-the-art methods is computationally expensive, and it does not meet real-time operational requirements in image processing pipelines found in consumer electronics applications. In addition, these applications may require that methods work with a single frame in imaging or video streams. That said, this work has the objective of proposing a novel method for the real-time removal of specular highlights from a single image. The essence of the proposed method is to match the histogram of the luminance channel of a pseudo-specular-free image using as reference the luminance channel of the input image. The operations performed by the proposed method have, at most, linear time complexity. In experimental evaluations, the proposed method presented competitive results when compared to the state of the art. The proposed method has high industrial applicability, and targeted use cases can take advantage of contributions of this work by incorporating the proposed method as a building block in image processing pipelines.
