Figure 10From: Chroma Noise Reduction in DCT Domain Using Soft-ThresholdingThis example shows a critical case. The images are 200% zoomed. On the left there are the images obtained by applying the JPEG encoder and by disabling the chroma denoiser; on the right are show the outputs of the JPEG with the chroma noise reduction enabled. As visible, some blocking artefacts are introduced, but they are progressively masked at lower bit rate.Back to article page
