摘要
研究了全变分最小化模型在图像去噪中的应用,用变分法推导出与之相应的偏微分方程,并用差分法对该方程进行了数值仿真。仿真试验结果表明,该方法在去除噪声的同时,能更好地保持图像边缘细节,具有较好的处理效果。
Image denoising technique based on minimization of the total variation(TV)is researched.The partial differential equations corresponding to it are also deduced,and the direct difference method is used to simulate the equation.Experimental results demonstrate that the method is effective for noise removal and can better preserve the sharp edge.It illustrates that the effect of total variation technique is excellent.
