An improved method for Rotation Estimation Using Photometric Spherical Moments

Using spherical moments to estimate the rotation of camera is an effective method. However, after the camera rotates, the scene in the captured image will change, which will cause a certain error. This paper proposes a method to reduce this error by removing the non-common part between the two images during rotation. Through multiple iterations, the error caused by scene changing will become very small. The experimental results using manual generated image are provided to show the efficiency of this proposed method.
