Abstract: A method to build a 3D model for a physical object includes the following steps. First, depth information of a plurality of images is converted into a plurality of 3D point clouds. Then, the motion parameters of the camera to gather each image relative to a previous image are determined according to the 3D point clouds. Next, a registration energy estimate value of each image's 3D point cloud, as being integrated into a previous image's 3D point cloud, is determined according to corresponding motion parameters. Then, the motion parameters are varied to minimize the estimate value. An optimal camera path is determined according to the varied motion parameters. Finally, a 3D model of the physical object is built according the optimal camera path.

Abstract: An electromagnetic shielding case and an electronic device having the same are introduced. The electronic device includes a PCB, which has at least one electronic component mounted thereon and is provided around the electronic component with multiple positioning holes. The electromagnetic shielding case includes a casing body internally defining a shielding space and multiple fixing pins formed on lower edges of the casing body corresponding to the positioning holes on the PCB. Each fixing pin includes a neck portion and an end portion with an angle included therebetween. After the fixing pins are correspondingly extended through the positioning holes, the end portions can be deflected by an angle to thereby hold the casing body to the PCB with the electronic component located in the shielding space and shielded against EMI. With these arrangements, the electromagnetic shielding case can be quickly mounted to and dismounted from the PCB.

Abstract: An electronic device having a heat-dissipating structure includes a housing, a printed circuit board, a heat-dissipating element, and a thermal conductive element. The housing has an opening and internally defines a receiving space. The printed circuit board is located in the receiving space and has an electronic component mounted thereon. The heat-dissipating element has a first surface and an opposing second surface, and is disposed above the printed circuit board to locate in the receiving space of the housing wile the first surface is exposed from the housing via the opening. The thermal conductive element is disposed between the heat-dissipating element and the electronic component for transferring heat generated by the electronic component to the heat-dissipating element, so that the heat is directly dissipated into ambient air via the opening. Accordingly, heat produced by the electronic component can be efficiently removed without accumulating in the electronic device.

Abstract: A method for achieving segmentation of a picture according to one aspect of the present invention comprises: determining a first foreground of a picture based on a predetermined mask; applying Gaussian Mixture Models with weighted data (GMM-WD) to the first foreground to generate a second foreground; determining a first background of the picture based on the second foreground; applying the GMM-WD to the first background to generate a second background; and determining an unknown region based on the second background and the second foreground.
