In order to remove the noise of infrared images,an image denoising method based on total variation was proposed,which inherits the advantage of edge preserving of the total variation(TV)model.A novel diffusion function was derived from the theory of smooth diffusion.Simultaneously,an edge detector operator was introduced to improve the related parameters of regularization term and fidelity term,which makes the denoised image avoid the staircase effect to a great extent.Finally,the implement of the algorithm was derived and the experimental results demonstrated the superior performance of the modified denoising algorithm.
