提出了一种对低对比度图像进行增强处理的新技术。在对传统的伪彩色增强技术改进的基础上,将小波分析和伪彩色两种方法有机地相结合,从而克服了这两种方法的缺陷,获得了良好的增强效果。同时对实现低对比度图像增强的基本方法和基本步骤进行了详细的阐述,并将该技术应用到透视图像分析中。实验结果证明了该方法的可行性,该方法为低对比度图像增强处理提供了一种新途径。 A new technique for enhancing low contrast images is proposed. Based on the improvement of the traditional pseudo-color enhancement technology, the two methods of wavelet analysis and pseudo-color are organically combined to overcome the shortcomings of the two methods and obtain a good enhancement effect. At the same time, the basic methods and basic steps to achieve low-contrast image enhancement are described in detail, and the technology is applied to the perspective image analysis. Experimental results prove the feasibility of this method, which provides a new approach for low-contrast image enhancement.
