An image signal design method based on structural similarity

文章为了表征具有结构相似性的数字图像测试信号,依据空间向量分解和合成原理,采用向量范数和夹角等参量,给出一种与空间结构相似性相关的测试图像设计方法,以及对应的设计实例和实验结果。该方法丰富了信号设计的类型,有利于结构相似性的标准测试信号的建立,以及结构化图像质量评价实验的考察。

Aiming at denoting the digital image test signals whose structure are similar, and based on the principles of decomposition and synthesis of image space vector, a test image design method in relation to the spatial structural similarity is given by using the norm and angle parameters of vectors. And the corresponding design example and experimental results are also presented. This method enriches the types of signal design, and it is conducive to the establishment of standard test signals whose structure are similar and the research on the structuralized experimental evaluation of image quality.
