The present invention is a method and system for measuring human emotional response to visual stimulus, based on the person's facial expressions. Given a detected and tracked human face, it is accurately localized so that the facial features are correctly identified and localized. Face and facial features are localized using the geometrically specialized learning machines. Then the emotion-sensitive features, such as the shapes of the facial features or facial wrinkles, are extracted. The facial muscle actions are estimated using a learning machine trained on the emotion-sensitive features. The instantaneous facial muscle actions are projected to a point in affect space, using the relation between the facial muscle actions and the affective state (arousal, valence, and stance). The series of estimated emotional changes renders a trajectory in affect space, which is further analyzed in relation to the temporal changes in visual stimulus, to determine the response.

The invention relates to a method of applying music to oviposition and insemination of four major Chinese carps and belongs to the technical field of fish propagation. In the artificial propagation of the four major Chinese carps, under the condition that parent fishes generate resistance to exogenous hormone drugs year by year, the music is introduced to induce estrus and spawning. In the invention, the music which is suitable for the estrus induction of fishes is selected and edited to corresponding segments and is correspondingly played according to emotional changes of the fishes from estrus beginning to spawning, ejaculation and insemination end phases to ensure that the fishes can naturally mate, spawn and inseminate under the synergistic action of the music and the hormone. Therefore, the problems that in the traditional artificial propagation of the four major Chinese carps, the fishes generate drug resistance because only the hormone drugs are injected to induce estrus and spawning, the estrus of the fish body is insufficient, and the parent fishes are wounded and the death rate is high because of forcibly extruding sperm and ovum artificially can be solved; and the method has the advantages of increasing the spontaneous labor rate of the parent fishes, reducing the death rate of the parent fishes and increasing the propagation efficiency of the fishes.
