The invention discloses a segment method to image sequences based on motion prediction and partial three-dimensional constraints and in combination with an active contour model and belongs to the technical field of image processing. The invention takes a control point on the active contour model as a starting point of the deformation of a prediction model; the method expresses the gliding property and consistency of object changes as the consistency of the position changes of the control point and predicts the position of a corresponding control point of a next image in the sequence with the changing trend of the control point and then adopts a diamond search algorithm used by MPEG-4 by taking a predicted position as a matched initial searching position. The invention introduces the notion of the partial three-dimensional constraints as one of the energies of the active contour model, which avoids the influences caused by wrong matching and achieves better predicting effect under the condition of simplicity and small computational amount.
