In this paper, a novel image sub-division and quadruple clipped adaptive histogram equalization (ISQCAHE) technique is proposed for the enhancement of low exposure images. The proposed method involves, computation of the histogram which includes a new approach of image sub-division, enhancement controlling mechanism, modification of probability density function (PDF) and histogram equalization (HE). The original histogram is segmented into sub-histograms based on exposure threshold and mean, to preserve the brightness and entropy. Then, individual sub-histogram is clipped separately to control the enhancement rate. For enhancing the visual quality, HE is applied to individual sub-histogram using the modified PDF. The experimental results show that, the proposed ISQCAHE method avoids the unpleasant artifacts effectively and provide a natural appearance to the enhanced image. It is simple, adaptive and performs superior than other techniques in terms of visual quality, absolute mean brightness error, entropy, Natural image quality evaluation, brightness preservation, structure similarity index measure and feature similarity index measure.
本文提出了一种新颖的图像细分和四重剪切自适应直方图均衡（ISQCAHE）技术，用于增强低曝光图像。所提出的方法涉及直方图的计算，包括图像细分的新方法、增强控制机制、概率密度函数（PDF）的修改和直方图均衡化（HE）。原始直方图根据曝光阈值和平均值分割成子直方图，以保持亮度和熵。然后，对各个子直方图分别进行剪切，以控制增强率。为了提高视觉质量，使用修改后的 PDF 对各个子柱状图进行 HE 处理。实验结果表明，所提出的 ISQCAHE 方法能有效避免令人不悦的伪影，并为增强后的图像提供自然的外观。该方法简单、自适应，在视觉质量、绝对平均亮度误差、熵、自然图像质量评估、亮度保持、结构相似性指数测量和特征相似性指数测量等方面都优于其他技术。
