- W171314095 abstract "This thesis uses the learner expression recognition of the E-learning system which can do some emotional cognitive interaction as the background. Firstly, we use a method which combines the method which based on skin color with the improved Adaboost algorithm to detect the learners face. On this basis, we use the gray scale which is smaller than a certain threshold value to count the vertical and horizontal pixel of the eyes image. Using the largest connected region quarter of the maximum of the count to locate the pupil center and the length of the axle. The experimental result shows that the method can quickly locate the pupil coordinate, and can be better to eliminate the spot and the impact of the eyelash." @default.
