摘要
为了提高园林景观图像的视觉效果和清晰程度,提出了多尺度Retinex算法的园林景观图像优化方法。利用模糊同组技术划分像素点中的平滑区域点、噪声点以及细节点,使用矢量中值滤波去除噪声点。在去噪后的图像中使用多尺度Retinex算法增强图像,分析平滑与细节区域点在局部窗口所占比例,融合单尺度增强结果实现图像初步优化,经动态截取拉伸操作恢复增强效果后的图像颜色,实现园林景观图像优化。经实验验证,该方法能够获得良好去噪和清晰优化效果的园林景观图像,同时还能够适当平衡图像对比度,保证图像具备良好的亮度和视觉效果。
In order to raise the visual effect and clarity of landscape image,the opti mization method of landscape image based on multi-scale Retinex algorithm is studied.The fuzzy group technology is used to divide the smooth region points,noise points and detail points,and the noise points are removed by using vector median filter.In the denoised image,the multi-scale Retinex algorithm is used to enhance the image,analyzing the proportion of smooth and detail area points in the local window,and the single scale enhancement results are fused to realize the preliminary optimization of the image,and the color of the enhanced image is restored by dynamic cutting and stretching operation to realize the optimization of landscape image.The experiment results show that the method can obtain good denoising and clear optimization effect of landscape image,and balance the image contrast properly to ensure that the image has good brightness and visual effect.
