| 摘 要： | 鉴于高速摄像图像亮度低、对比度差的缺点,提出基于小波分析技术将高速摄像图像进行增强处理.首先将图像进行小波分解;分别对低频、高频小波系数放大;最后通过将处理后的小波系数重构,实现对高速摄像图像增强;并且介绍了选择不同小波基、放大系数对图像增强效果的影响.利用MATLAB程序中小波分析的工具箱可以轻松地实现增强处理.处理结果证明了该方法的可行性,该方法为提高高速摄像图像质量提供了一种新途径.

| Abstract: | Because of the weakness of the lower brightness and contrast of the high-speed photography system,a method of wavelet analysis technique is presented to enhance the image quantity.Using the wavelet analysis,the high and low frequency decomposing coefficients are enhanced,and the influence of the different wavelets is introduced and the coefficients to the images are amplifited.Making use of the wavelet toolbox of MATLAB program can handle the images easily.Experiment result proofs the feasibility of the method.The method provides a new approach to increase the image's quantity of high-speed photography. |
