Abstract: An electronic device is disclosed. The electronic device includes an inertial measurement element and a processor. The inertial measurement element is configured to obtain a first inertial measurement data when the electronic device moves. The processor is configured to perform the following operations: establishing a mixed reality environment coordinate system in correspondence according to the real space, and calculating a starting coordinate point of the electronic device in the mixed reality environment coordinate system; converting the first inertial measurement data into a first movement vector in the mixed reality environment coordinate system according to an inertial measurement data mapping model; calculating a first spatial operation point in the mixed reality environment coordinate system according to the starting coordinate point and the first movement vector in the mixed reality environment coordinate system; and executing a 3D scene editing program with the first spatial operation point.

Abstract: An extended reality space generating apparatus and method are provided. The extended reality space generating apparatus generates a plurality of plane plates, a plate coordinate and a normal vector corresponding to each of the plane plates based on a plurality of point clouds, wherein the point clouds correspond to a real space. The extended reality space generating apparatus compares the plate coordinates and the normal vectors of the plane plates in a visual window to generate an effective plane plate set. The extended reality space generating apparatus generates an extended reality space corresponding to the real space based on the effective plane plate set.

Abstract: The present invention provides a method for tracking face in a video, comprising steps of taking an image sample from a video; extracting and storing a target face feature according to the image sample; dividing the video into one or more scene; and labeling one or more face matching the target face feature. Accordingly, an actor's facial expression and motion can be extracted with ease and used as training materials or subject matters for discussion.

Abstract: An image processing method and an image processing device are provided. The image processing method includes the following steps. A light source is projected onto a 3D model via a plurality of projecting locations to generate a plurality of facial shadow pictures. The facial shadow pictures are superimposed to generate a composite shadow picture. An eye-eyebrow location, a nose location and a mouth location in a 2D facial map are obtained by way of analyzing according to the composite shadow picture. A plurality of characteristic points are calculated according to the eye-eyebrow location, the nose location and the mouth location in the 2D facial map.
