Combining with the advantages of curvelet transform and TV model
proposes a denoising method based on curvelet transform and TV model
which detects the edges of the image with the high-frequency coefficients of curvelet transform
introduces the edge detecting function to guide the TV model diffusion
the new model can not only remove noise
but protect the edges of the image.use peak signal-to-noise ratio to evaluate the denoising results
the experimental results show that the denoising effect of the new model is significantly better than that of the curvelet transform threshold method and TV model.
