Abstract: An activity recognition method and a computer-readable media are disclosed. The activity recognition method is applied to an activity recognition system configured to recognize several activities. The activity recognition method includes: obtaining an original activity image corresponding to a first time point, wherein the original activity image includes several pixels indicating whether several sensors are triggered; determining an image feature according to a second activity corresponding to a second time point, wherein the second time point is prior to the first time point; integrating the original activity image and the image feature to generate a characteristic activity image; and determining a first activity corresponding to the first time point according to the characteristic activity image.
