An evaluation method of lower limb motor ability based on improved convolutional neural network |
| abstract |
The invention discloses a lower limb movement ability evaluation method based on an improved convolutional neural network. The depth data is binarized by the bilateral filtering method to obtain the gait contour image; the knee joint angle is calculated by the space vector method; the gait contour feature of the gait contour image is extracted by the improved convolutional neural network; The contour feature and the knee joint angle were serially combined and normalized, and then the feature dimension was reduced by the kernel principal component analysis method. This method automatically extracts video image features by using an improved convolutional neural network with a spatial pyramid pooling layer and COCOB optimization algorithm added to the traditional convolutional neural network, which greatly reduces the complexity and improves the evaluation accuracy. |
