摘要： A method, an image processing device, and a system for generating a disparity map are proposed. The method includes the following steps. Images of a specific scene are captured by two image sensors to generate two original images. A shrinking process is performed on the two original images to generate two shrunk images. A shrunk disparity map is generated by using the two shrunk images. A magnifying process is performed on the shrunk disparity map to generate a magnified disparity map. Whether each magnified disparity value of the magnified disparity map is reliable is determined so as to accordingly generate a refined disparity map.

摘要： A living body detection method and a living body detection system are provided. A radio-frequency signal reflected by an experiment living body is received, and raw sampling data of the RF signal are obtained. A feature extraction process is performed to generate initial training features of sampling datasets, wherein the initial training features respectively correspond to feature generation rules. A classification prediction model is established according to a posture of the experiment living body and the initial training features, and correlation feature weightings respectively corresponding to the initial training features are obtained. Preferred features corresponding to at least one of the feature generation rules are selected from the initial training features according to the correlation feature weightings. Another classification prediction model configured for determining a posture of a detection living body is established according to the posture of the experiment living body and the preferred features.

摘要： A live facial recognition method includes capturing a plurality of images of a face of a subject under recognition; obtaining time-varying data according to the images, the time-varying data representing a periodic variation of facial color of the subject under recognition due to facial vasoconstriction and vasodilation caused by heartbeat; and comparing the time-varying data with a predetermined frequency range. The subject under recognition is determined to be a living subject when the time-varying data is within the predetermined frequency range.

摘要： An electronic device includes a first main body, a second main body, a pivoting mechanism, and a heat dissipation module. The second main body includes a first housing, a second housing, and a cover plate. The pivoting mechanism is pivotally connected between the first main body and the second main body. Two sides of the cover plate are pivotally connected to the second housing and the pivoting mechanism respectively. The heat dissipation module is disposed in the second main body and includes at least one elastic member. The elastic member is fixed between the first housing and the cover plate. In response to that the first main body is in unfolded position relative to the second main body through the pivoting mechanism, the pivoting mechanism drives the cover plate to be located between an open position relative to the second housing, so that the elastic member is stretched.

摘要： A telescopic fan cage includes a main frame and a side frame which are slidably connected with each other to form a fan installation space. The side frame is capable of sliding toward the main frame to shrink the fan installation space, or sliding away relative to the main frame to expand the fan installation space. An apparatus case includes a casing and the telescopic fan cage. The telescopic fan cage is detachably disposed in the casing. Therein, the side frame is capable of sliding toward the main frame to shrink the fan installation space, so that the telescopic fan cage is at a transit state for moving in or out the casing; the side frame is capable of sliding away relative to the main frame to expand the fan installation space, so that the telescopic fan cage is at an installation state for being fixed in the casing.

摘要： A case module that is capable of installing a first electronic module and a second electronic module, includes a cage and a restraining component. The first electronic module can move relative to the cage to a first installation position along a first direction. The second electronic module can move relative to the cage to a second installation position along a second direction perpendicular to the first direction. When the first electronic module moves relative to the cage toward the first installation position along the first direction, the restraining component is driven to move relative to the cage toward a restraining position along the first direction. The second electronic module can be stopped by the restraining component when the restraining component is located at the restraining position.
