| 摘 要： | 目的探讨利用MATLAB的小波变换进行图像压缩的方法。方法对图像进行小波变换,保留低频部分,高频部分置0。结果第一次压缩时压缩效果较好,压缩比较小,第二次压缩时压缩较大,图像视觉效果也令人满意。结论本方法是一种简单、有效的压缩方法。

| Abstract: | Objective: To study the method of image compression based on wavelet transform.Methods: The image was processed by wavelet transform,and then the information of low frenquency was retained and the information of high frenquency was home zero.Results: The quality of the first image compression was high,but the compression ratio was low.The compression ratio of the second time was higher,and the image quality was good.Conclusion: The method is simple,reliable and effective in image compression. |
