图像质量客观评价方法研究与实现

Research on Objective Evaluation Methods in Image Quality Filed

本文对图像质量主观评价和客观评价方法进行了介绍和优缺点分析,针对主观评价方法耗时耗力、随机性大等缺点,构建了一种图像质量客观评价模型,介绍几种常用的图像质量客观评价算法并对其进行计算机仿真,实现了多路图像质量高低定量排序.进行对比实验,对该图像质量客观评价模型进行验证,实验结果表明该模型所采用的客观图像质量评价与主观评价基本保持一致.

The advantages and disadvantages of subjective evaluation and objective evaluation methods in image quality filed were introduced in this paper.Some algorithms for image quality objective evaluation were expounded aiming at time-consuming and randomicity of subjective evaluation method.A comparative experiment was conducted to verify the objective evaluation model of image quality.The experiment results showed that the objective image quality evaluation adopted by the model was basically consistent with the subjective evaluation.
