  • Publication number: 20240129519
    Abstract: Implementations of the disclosure provide systems and methods for motion refinement in a video. The method may include determining an initial motion vector for a video block of a video frame from the video. The method may include determining a matching target based on a weighted combination of a first reference block from a first reference frame in the video and a second reference block from a second reference frame in the video. The method may include performing a bilateral matching based motion refinement process at a block level to iteratively update the initial motion vector based on the matching target until a refined motion vector is obtained. The method may include refining a motion vector for each sub-block in the video block using the refined motion vector of the video block. Refining the motion vector at a sub-block level applies an affine motion model of the video block.

  • Patent number: 7113403
    Abstract: A centrifugal fan type cooling module includes a centrifugal fan and a radiator. The centrifugal fan provides a fan rotor with fan blades and an axial shaft and a fan stator set with an axial core, an upper cover and a frame. The fan blades extend straight forward radially with the outer end of each fan blade has an enlarged curve end part and the rest part of the respective fan blade has a width shorter than the axial shaft. The frame encloses and fits with the top of the radiator and the axial shaft is rotationally joined to the axial core such that a hollow space is formed between the radiator and the fan rotor. Heat from an electronic component is transmited to the radiator and removed outward quickly in all directions by way of upward suction force of the centrifugal fan instead of contacting other electronic members directly.
