| 目的 对数字印刷品大面积填充区域非均匀性感知质量的综合评价方法及其评价模型进行了研究。 方法 结合噪声功率谱和人眼视觉传递函数计算数字印刷品非均匀性质量指标,利用心理物理学实验获得人眼视觉对数字印刷品大面积填充区域非均匀性的主观感知评价得分,通过对 200 个印刷色块的主客观质量评价实验创建了非均匀性感知质量评价模型。 结果 非均匀性质量指标能较好地反映大面积填充区域在人眼视觉中的感知质量,非均匀性质量评价模型可有效提供定量的非均匀性感知质量综合评价。 结论 采用定量方式描述数字印刷品非均匀性的综合评价是完全可行的,具有很好的实用性和现实意义。 |

| Objective To study the comprehensive evaluation method and evaluation model for the perceptual non-uniformity quality of large areas in digital prints. Methods The non-uniformity quality metric was calculated to measure the integrated non-uniformity of the digital prints based on noise power spectrum and human vision transfer function, the subjective perceptual evaluation scale was obtained through psychophysical experiment, and the quality evaluation model for the visual perception of digital prints爷 non-uniformity was created based on the objective and subjective quality evaluation experiments for 200 digital printed patches. Results The results showed that the quality metric well reflected the perceptual quality of the large printed area, and the evaluation model provided a valid quantitative and comprehensive evaluation results. Conclusion It is feasible and practical to evaluate the non-uniformity of digital prints comprehensively and quantitatively. |
