基于小波变换的林业图像处理研究

Forestry Image Processing Based on Wavelet Transform

从工程应用角度出发,介绍了二维离散小波变换的一般形式,应用二维小波分析技术对图像进行消噪、压缩等处理,指出小波变换在图像处理中有着较好的效果,具有压缩比高、速度快、去噪效果好的优点, 这是由于小波的多分辨率特性决定的。

This paper has briefly introduced the wavelet transform and its application in image procession, such as denoising and compressing, and pointed out that image procession with wavelet technology has such characteristics as high compression ratio, rapid speed, good denoising effect, etc. , and this is depended on the wavelet multiresolution.
