Head Pose Estimation: c# & 3D math

Estimate the rotation of human face/head (refer image: [login to view URL]) from the provided coordinates. The input to the system is the x,y coordinates of a human face. (refer image: face coordinates [login to view URL]) You have to find the method/algorithm which can estimate the rotation of the face/head, ie, Yaw, Pitch, Roll of the face/head. (refer image:[login to view URL]). You also have to estimate the center of the head in x,y coordinates of the image. Acceptance criteria: * Maximum tolerance is 5%. * A total of 50 test cases will be provided. All should pass Language: c# Tool: VS2010 A basic system for parsing the coordinates from the XML is also attached (refer: [login to view URL]). After unzipping this file, you can see a folder named "imgNxml", where you can see 5 test-cases. example: [login to view URL]
