Embodiment Construction
[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0030] A method for evaluating visual comfort of stereo images based on multi-scale dictionaries proposed by the present invention, its overall realization block diagram is as follows figure 1 As shown, it includes two processes of training phase and testing phase; in the training phase, multiple stereo images of five different comfort levels are selected to form an initial training image set; and then by obtaining each stereo image in the initial training image set The disparity statistical feature vector and the neural response feature vector of each stereo image in the initial training image set are obtained to reflect the visual comfort feature vector; then according to the initial training image set of all stereo images for reflecting the visual comfort The feature vector constructs a multi-scale dictionary, and determines the multi-scale...
