【摘要】 Contourlet是一个真正的二维图像表示方法,变换由两层滤波器组成:拉普拉斯变换和多方向分解。Contourlet变换可以实现多分辨率和多向分解灵活掌握图像,与小波变换相比较,Contourlet变换首先提出将离散域数字化,然后扩展到连续域分析其属性,它能够更方便地将图像呈现出来。更多还原

【Abstract】 Contourlet is a true two-dimensional image representation,its transform consists of two layers of filter: Laplace transform and multi-directional decomposition.Contourlet transform can achieve multi-resolution and multi-image decomposition to flexibly grip the image.Compared with wavelet transform,Contourlet transform firstly proposes the digitized discrete domain,and then extends to the continuous domain to analysis its properties,it can be more convenient to present the image.更多还原
