This work shows the performance evaluation of a face tracking features algorithm, applying active shape models (ASM) and using the Kinect sensor as the capture image device. The development was implemented by using OpenCV libraries, in a laptop with processor core i5 at 2.4 GHz, 4 GB of RAM, and Windows 7 operative system. In order to perform the evaluation, the algorithm was run to analyze the response under different facial expression poses. The stabilization times of the points over the image were measured and the localization of the points in the image was manually evaluated. The face was divided in regions: face contours, eyebrows, nose, eyes and mouth. Finally, the results are presented as the average time of the face matching, the average number of frames required to perform matching, and the average error of the positioning in different faces conditions. The results show the strength of this work and the adaptability for future work.
