1. A method for pose estimating, the method comprising: recognizing, by way of a processor, a pose of a user from a depth image; estimating the pose of the user based on a result of the recognition; recognizing the pose of the user from a subsequent depth image when a confidence of the result of the recognizing satisfies a predetermined condition; tracking the pose of the user, using a user model when the confidence of the result of the recognizing fails to satisfy the predetermined condition; and estimating the pose of the user based on a result of the tracking.
