Three-dimensional correlation filter sequence action recognizing method and device

The invention relates a three-dimensional correlation filter sequence action recognizing method and a three-dimensional correlation filter sequence action recognizing device. The three-dimensional correlation filter sequence action recognizing method comprises the following steps: firstly, establishing a sample database, and acquiring a training sample video column vector in allusion to a specific sequence action; secondly, establishing an action video maximum average correlation filter template, and acquiring a three-dimensional maximum average correlation height filter of the specific sequence action; and finally, comparing an optimized filter response value with a set threshold value, and judging whether the specific sequence action exists in a video to be detected. The three-dimensional correlation filter sequence action recognizing device comprises the three-dimensional maximum average correlation height filter, a filter response calculating module, a filter response optimizing module and a specific sequ
