The invention provides a method for changing up and down TDD (Time Division Duplexing) configuration. The method comprises the steps that user equipment measures interference of user equipment in an adjacent cell to the user equipment and reports the interference situation to a base station, and the base station changes the current up and down TDD configuration according to the interference situation reported by the user equipment and the current up and down service requirements. The method meets the requirement of the dynamically changing up and down service load under the condition that the serious interference between the adjacent cells is not caused.

A method and system for incorporating voice commands into the interactive process of image segmentation. Interactive image segmentation involves a user pointing at an image; voice commands quicken this interaction by indicating the purpose and function of the pointing. Voice commands control the governing parameters of the segmentation algorithm. Voice commands guide the system to learn from the user's actions, and from the user's manual edits of the results from automatic segmentation.
