According to the characteristics of space domain, the cervical vertebra video picture dynamic selection is carried out.Through image processing and pattern recognition technology, video images for neck movement areAutomatically analyze the patient's cervical spine image in each video image.Using the first blank area on the left side of the patient's cervical spine image,And the proportion of the second blank area on the right side of the patient's cervical spine image in the whole video image and the position of the cervical spine.Calculate the degree of variation of neck flexion or / and neck extension in the patient's cervical spine image.It is used to select a picture image with equal degree of variation during neck bending or / and neck extension.It can provide a more convenient and accurate analysis of movement trajectory of cervical vertebra for medical staff.一種依據空間域特性進行頸椎視訊畫面動態選擇，針對頸部運動之視訊畫面透過影像處理以及圖形識別技術，自動分析每一張視訊畫面中病患頸椎圖像，利用病患頸椎圖像左側的第一空白區，及病患頸椎圖像右側的第二空白區所佔整個視訊畫面的比例以及頸椎所在位置對照，計算出病患頸椎圖像中頸部彎曲或/及頸部伸展的變異程度，用以選擇出頸部彎曲或/及頸部伸展動作過程變動程度均等的畫面影像，可提供醫療人員更方便且更精確之頸椎動作時移動軌跡分析。
