Embodiment Construction
[0057] like figure 1 As shown, a video semantic segmentation method based on optical flow feature fusion provided by the present invention includes the following steps:
[0058] Step 1, determine that the current video frame image of the video sequence is a key frame image or a non-key frame image; if it is a key frame image, then perform step 2, if it is a non-key frame image, then perform step 3;
[0059] Step 2, extracting the high-level semantic feature map of the fusion position-dependent information and channel-dependent information of the current video frame image;
[0060] Step 3, obtaining the high-level semantic feature map of the current video frame image by calculating the optical flow field;
[0061] Step 4: Upsampling the high-level semantic feature maps obtained in steps 2 and 3 to obtain a semantic segmentation map.
[0062] The features and performances of the present invention will be further described in detail below in conjunction with the embodiments.
