Hollywood at that time, because of the monopolization of the so-called ＂eight movie companies＂, the shooting and operation of a film followed rigorous steps of ＂producer system.＂ The target of the ＂producer system＂ entirely aimed at the market in order to get the maximum profits; therefore, although this system brought a lot of money to the film industry, it also limited the filmmakers＇ play space. Thus, a group of filmmakers got rid of the eight movie companies＇ control and made self-financing, or even wrote and direct red by themselves, they shot a lot of strong ideological films which were different with commercial films, known as the＂ Independent Film ＂.展开更多

Based on the assumption that similar persons have similar facial expression appearance and shape, the person-similarity weighted expression feature is proposed to estimate the expression feature of test persons. As a result, the estimated expression feature can reduce the influence of individuals caused by insufficient training data, and hence become less person-dependent. The proposed method is tested on Cohn-Kanade facial expression database and Japanese female facial expression （JAFFE） database. Person-independent experimental results show the superiority of the proposed method over the existing methods.展开更多
