Embodiment Construction
[0055] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.
[0056] This implementation example discloses a moving target extraction method based on difference and semantic information fusion, such as figure 1 shown, including the following steps:
[0057] S1. Acquire N frames of image sequences from the zoom dome camera;
[0058] The image frames acquired from the zoom dome are all 3-channel 24-bit RGB images, and the length of the image sequence needs to be kept as N. In order to reduce the impact of noise on subsequent steps, all acquired image frames need to be firstly filtered by Gaussian. The Gaussian kernel expression used is as follows:
[0059]
[0060] When the image sequence is initialized, all image frames in the sequence use the first frame. As the number of acquired frames increases, the replacement starts. Wh...
