[0067] The implementation process of the present invention will be further described below in conjunction with the accompanying drawings.
[0068] Such as figure 1 Shown, the present invention provides a kind of baby abnormal behavior detection method based on meanshift algorithm and SVM, comprises the following steps:
[0069] 1. Obtain baby videos and perform unified preprocessing.
[0070] 2. Cut the baby video in step 1 into 15s as a copy, and name it uniformly, and name the images converted into frames uniformly.
[0071] 3. Tracking of the infant’s movement trajectory: For the frame image obtained in step 2, use the meanshift algorithm to track the infant’s limbs and the overall movement trajectory of the whole body, specifically including the following steps:
[0072] 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 Epannechnikov kernel function, a...
