Embodiment Construction
[0075] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0076] A method for objective evaluation of stereoscopic image quality based on image decomposition proposed by the present invention, its overall realization block diagram is as follows figure 1 As shown, the process is as follows:
[0077] Firstly, three-level wavelet transform is performed on the left view image of the original undistorted stereo image and the left view image of the distorted stereo image to be evaluated, and then according to the obtained wavelet coefficients of the three direction subbands corresponding to each wavelet transform Matrix, to obtain the restored image and interference image of the left viewpoint image of the distorted stereoscopic image to be evaluated; similarly, implement 3 levels for the right viewpoint image of the original undistorted stereoscopic image and the right viewpoint image of the distorted ste...
