摘要： A depth detection method includes the following steps. First, first and second video data are shot. Next, the first and second video data are compared to obtain initial similarity data including r×c×d initial similarity elements, wherein r, c and d are natural numbers greater than 1. Then, an accumulation operation is performed, with each similarity element serving as a center, according to a reference mask to obtain an iteration parameter. Next, n times of iteration update operations are performed on the initial similarity data according to the iteration parameter to generate updated similarity data. Then, it is judged whether the updated similarity data satisfy a character verification condition. If yes, the updated similarity data is converted into depth distribution data.

摘要： A gesture detecting method includes steps of defining an initial reference point in a screen of an electronic device; dividing the screen into N areas radially according to the initial reference point; when a gesture corresponding object moves in the screen and a trajectory of the gesture corresponding object crosses M of the N areas, selecting a sample point from each of the M areas so as to obtain M sample points; and calculating a center and a radius of the trajectory of the gesture corresponding object according to P of the M sample points so as to determine a circular or curved trajectory input. Accordingly, the invention is capable of providing a center, a radius, a direction and an arc angle corresponding to a gesture in real-time without establishing a gesture model.

摘要： A system for estimating a location of an occluded skeleton, a method for estimating a location of an occluded skeleton and a method for reconstructing an occluded skeleton are provided. The method for estimating a location of an occluded skeleton comprises the following steps: Firstly, a trace of a reference central point of a body is estimated according to a plurality of continuously moving images. Next, a human movement state is estimated according to the trace and a motion information of the continuously moving images free of skeleton occlusion. Then, a possible range of the occluded skeleton for maintaining human balance is calculated according to the human movement state. Afterwards, a current motion level of the occluded skeleton is predicted according to a historic motion information of the occluded skeleton. Lastly, the location of the occluded skeleton is estimated according to the current motion level and the possible range.
