Abstract: Computer automated interactive activity recognition based on keypoint detection includes retrieving, by one or more processors, a temporal sequence of image frames from a video recording. The one or more processors identify first and second keypoints in each of the image frames in the temporal sequence using machine learning techniques.

Abstract: Provided are a series of crocins compounds and related pharmacological applications thereof in prevention and treatment of Alzheimer's disease. The series of crocins compounds are obtained by taking the Chinese herb, namely Gardenia jasminoides Ellis, as a raw material and separating same by means of various methods. The compounds playing a role in preventing oxidative injury caused by hydrogen peroxide (H2O2) and excitatory amino acid injury caused by L-glutamic acid are screened out by in-vitro cell experiments. The results show that the crocins compounds have good effect in preventing cell injury caused by H2O2 and L-glutamic acid. The compounds have good effect in preventing and treating Alzheimer's disease due to the fact that significant rise of oxidative stress and excitatory amino acid is a key factor for nerve injury in Alzheimer's disease, and have broad development and application prospect.
