To this end, this research proposes a deep learning-based color correction framework and a halftoning algorithm developed from previous methods to effectively enhance the accuracy of color reproduction and spatial continuity, overcoming the limitations of traditional approaches. To validate the method's feasibility and real-time performance on edge computing devices, we deployed the model on an NVIDIA Jetson Orin NX and employed a post-training quantization strategy to convert the model from full precision to INT8 precision. Experimental results demonstrate that the quantized model achieved a nearly five-fold increase in inference speed with only a slight degradation in image quality, significantly reducing memory and computational resource requirements. This research provides a low-cost, high-efficiency, and measurement-free AI color tuning solution.電子紙深度學習顏色校正半色調演算法邊緣運算色調再現E-paperDeep LearningColor CorrectionHalftoning AlgorithmEdge ComputingTone Reproduction學術論文
