(a) Comparison of warping methods across a broad range of denoisers shows that the overall denoising performance is greatly improved when data warping is performed. (b) Without warping, the denoising performance is suboptimal, especially for the GP denoiser, which performs similarly to other traditional denoising methods. (c) With stationarity warping, the denoising performance drastically improves for all methods, and classical denoisers can perform as well as modern denoisers without warping. The red dashed line indicates how similar the denoised signal is to our `clean' reference spectrum, with values below unity representing improved quality.
