摘要： Provided is a system that estimates pose data of a person with high accuracy at low cost. At a time step at which image data is to be captured and obtained, a pose data generation system obtains pose data based on the image data. At a time step at which image data is not to be obtained, the pose data generation system predicts pose data at a current time step from a previous time step using IMU data and performs interpolation processing to obtain pose data. Thus, even when a rate of obtaining the image data is low, the pose data generation system performs the above interpolation processing using IMU data to obtain pose data with a high frame rate.

摘要： Provided is a processor for a neural network whose high-performance compact model can be incorporated into low-spec devices such as embedded devices or mobile devices without requiring re-training. The processor for a neural network, which uses a multi-valued basis matrix, widens the range of integer values that can be taken by each element of the multi-valued basis matrix; thus, the number of dimensions (the number of elements) of a scaling coefficient vector is reduced accordingly. The elements of the scaling coefficient vector are real numbers, and thus reducing the amount of processing of real number calculation processing allows for reducing the number of dimensions (the number of elements) of the scaling coefficient vector. As a result, this neural network processor significantly reduces the amount of calculation processing while ensuring the calculation accuracy when performing matrix calculation processing using the binary basis matrix.
