Abstract
A video stream captured for an object is obtained. Features of S image frames in the video stream are extracted, and S N-dimensional feature vectors are generated. The S N-dimensional feature vectors are arranged in a chronological order corresponding to the order in which the image frames occur in the video stream to generate a feature matrix, wherein the feature matrix has N rows and at least S columns. The feature matrix is processed by using a pre-trained convolutional neural network, to obtain a processing result for the object captured in the video stream.
