Face　recognition　is　a　popular　research　technique　in　the　field　of　computer　science.　Kinect　is　a　popular　somatosensory　device,　and　it　can　take　advantage　of　the　special　characteristics　of　Kinect　devices　to　play　its　advantages　in　the　study.　This　paper　mainly　describes　the　technology　of　face　recognition　as　the　center,　face　recognition　technology　research　background　and　significance　of　Chinese　and　foreign　research　status　of　facial　expression　recognition　technology　are　introduced,　including　facial　expression　recognition　of　the　significance,　the　development　direction　of　the　technology　and　algorithms　of　expression　feature　extraction　and　expression　recognition,　based　on　the　commonly　used　Kinect.　This　article　also　describes　the　use　of　Kinect　on　the　human　face　location,　as　well　as　facial　features　extraction　algorithm　selection　and　Hog　feature　extraction　principle.　Finally,　the　SVM　classifier　and　algorithm　analysis　are　introduced.
