Video target segmentation method, device and equipment

The invention provides a video target segmentation method, device and equipment, and the method comprises the steps: carrying out the segmentation target region labeling of a first frame of image in avideo, and obtaining a segmentation target label; sequentially predicting each frame of image according to a time sequence through a video target segmentation network by utilizing the first frame ofimage and the segmentation target label to obtain a segmentation thermodynamic diagram of each frame of image, wherein the prediction comprises the step of predicting a next frame of image by utilizing a previous frame of image and a prediction result of the previous frame of image; and carrying out binarization processing on the segmentation thermodynamic diagram to obtain the segmentation targetarea. According to the method, multi-frame feature information can be effectively combined, target segmentation in the query frame is guided, the target segmentation result is more accurate through the transformation predictio
