Randomized trial demonstrates high-fidelity image processing in visual graphic design, improving color reconstruction accuracy.

This research aims to develop a high-fidelity framework for colorless image processing that overcomes limitations of traditional methods.
Developed a dual-channel processing pipeline for RGB-D images.
Implemented a weighted non-local Laplacian algorithm and a brightness-guided edge preservation mechanism.
Conducted rigorous testing on benchmark datasets including Middlebury Stereo and MIT-Adobe FiveK.
Reduced color reconstruction error to 0.020 ± 0.003, a 60% improvement over the Welsh method.
Achieved a PSNR of 38.5 ± 0.4 dB and SSIM of 0.942 ± 0.008 with 9.4 FPS on MIT-Adobe FiveK.
Improved matching recall from 62.3% to 91.4% ± 2.1% while reducing semantic alignment error from 12.4 to 3.1 ± 0.7 pixels.
