基于斜坡边缘模型的经典插值方法把所有边缘归为强边缘,导致弱边缘过分增强而失真。
Classical interpolation method based on ramp edge model considers all the edges as strong edges, which results in weak edges' distortion.
定量的全参考和弱参考质量评价方法必须借助原始的非失真图像作为参考,从而使他们的应用范围受到极大限制。
The full-reference and reduced-reference image quality assessment assume the knowledge of a reference image. This assumption limits their application domain.
