Joseph has excellent judgment for his research and work. He showed this ability in his master thesis and scientific projects. After surveying the references or materials, Joseph would analysis them based on all his knowledge and objectively. Even more, he would conduct some experiments to verify the correctness of the paper or information which he acquired. For example, many articles claimed that the ASM algorithm has excellent accuracy in detecting the contour of eyes and lips. However, Joseph kept his skeptical about verifying those paper’s methods and found that the result was not as excellent as they said. Therefore, improving the accuracy of localizing the contour of mouth and eyes is one of the critical parts of his master thesis. It is a piece of excellent evidence that he has excellent judgment.
