The document proposes a novel hybrid image denoising technique based on trilateral filtering and Gaussian conditional random field modeling. It combines trilateral filtering, which is an edge-preserving Gaussian filter, with Gaussian conditional random fields to deal with different noise levels in images. The technique involves first applying trilateral filtering to smooth the image, then using Gaussian conditional random fields on the smoothed image. Experimental results on test images show the proposed technique achieves better denoising performance than traditional trilateral filtering alone, as measured by higher peak signal-to-noise ratios and lower mean squared errors.
