摘要：In this paper, we propose a method for the detection of actual moving objects in a moving image obtained by a moving camera. First, we construct a basic method for the detection of actual moving objects by utilizing motion signals of a camera. In this method, actual moving objects are detected based on the difference between the actual image flow observed and the predicted image flow computed by utilizing motion signals of a camera. The basic method has some requirements which are difficult to satisfy, such as exact computation of depth values in the surroundings. Therefore, we improve this method to perform the correct detection of actual moving objects without depth signals. In the improved method, the detection is performed based on whether the actual image flow is involved in a subregion of the image flow which is computed as that of stationary objects or not. In this method, the exact computaion of depth values in the surroundings and the computation of a speed component for the translational motion of a camera are not required.
