[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0026] A non-reference high dynamic range image objective quality evaluation method based on tensor space proposed by the present invention, its overall realization block diagram is as follows figure 1 As shown, it includes the following steps:
[0027] ① Denote the distorted high dynamic range image to be evaluated as S dis ; then put S dis Represented in the form of a third-order tensor, denoted as V dis ; Then use the existing Tucker3 decomposition algorithm to V dis Perform tensor decomposition to obtain V dis The kernel tensor of , denoted as ξ dis ; Then put ξ dis The 1st channel of the S dis The first eigenimage of ξ will be dis The 2nd channel of the S dis The second eigenimage of ξ will be dis The 3rd channel of the S dis The third eigenimage of ; where, S dis has width W and height H, S dis for color images.
