中文摘要: 提出了一种快速的自适应图像增强算法。算法首先对原始图像进行高斯平滑滤波，然后根据原始图像的整体信息和局部信息对图像的像素值进行偏移。最后，利用偏移后的图像信息和非线性函数对图像进行变换，从而实现了对图像细节的增强。通过将RGB图像变换到HSV彩色空间，将增强算法推广到了彩色图像的处理。实验结果表明，该算法运行速度快，能有效改善图像质量。同时能够根据环境的亮暗，自动调整增强效果，具有自适应的功能。
Abstract:A fast and adaptive algorithm for image enhancement is proposed. The algorithm first filters the image with Gaussian smoothing filter, and then offsets the image pixel values on the basis of global and local information. Finally, the offset pixel values and non-linear function is used to transform the image, thus enhancing the details of the image. By transforming the RGB image to HSV space, the method is extended to the color image enhancement. Experimental results demonstrate that the proposed method can efficiently improve image quality, and can also self-adaptively adjust the enhancement according to the environment.
