[0062] The implementation process of the present invention is further described below in conjunction with the accompanying drawings.
[0063] like figure 1 As shown, the present invention provides a method for detecting abnormal infant behavior based on meanshift algorithm and SVM, comprising the following steps:
[0064] 1. Obtain baby videos and perform unified preprocessing.
[0065] 2. Take 15s of the baby video in step 1 into one copy, and name them uniformly. The images converted into frames are also named uniformly.
[0066] 3. Baby motion trajectory tracking: For the frame images obtained in step 2, the meanshift algorithm is used to track the baby's limbs and the overall motion trajectory of the whole body, which specifically includes the following steps:
[0067] 3.1 Select the kernel function of the meanshift operator, and weight each sample point according to the distance from the center point. The kernel function we use is the Epantechnikov kernel function, and...
