Abstract: Various embodiments include techniques for encoding media frames using a multistage search without the processing overhead of pyramidal motion estimation techniques. The first stage of the multistage search generates many motion vectors, where each motion vector is based on a small range full pixel search of a pixel group in the media frame. The video encoder selects a full pixel best motion (FBM) vector for all pixel groups from the motion vectors generated during the first stage. The second and subsequent phases of the multistage search is based on the FBM vector from the prior stage as a starting point, where the search range for each subsequent phase is larger than the search range of the prior stage. The multistage search can be performed over a fixed number of stages. Alternatively, the multistage search can be terminated when the cost value for the current stage is below a threshold value.

Abstract: A nailing machine includes a closed first cylinder having a first working chamber and a second cylinder enclosed outside the first cylinder and having a second working chamber. The first working chamber communicates with the second working chamber. A first piston coupled to a striking pin having a limiting portion is installed inside the first cylinder, The nailing machine also includes a locking mechanism including a locking arm coupled to an upper part of a transmission shaft, and a swing arm coupled to the lower part. A second piston in the second cylinder is driven by a motor assembly to reciprocate. When the second piston is in the first position, the first piston moves inward and the limiting portion is engaged by the locking arm. When the second piston is in the second position, the motor assembly rotates the swing arm, disengaging the locking arm from the limiting portion.

Abstract: The present disclosure discloses a method and system for reconstructing missing information in a damaged turbulent flow field. A second mask is randomly generated based on a first mask and is utilized in the network training, which significantly enhances the generator network's ability to recognize multiple damaged regions and generalize different damage forms. A combined loss function is introduced, which not only evaluates the overall difference between a reconstructed turbulent flow field and an original turbulent flow field, but also evaluates the difference in feature mapping at different levels of a pretrained network. This dual evaluation ensures accurate reconstruction of flow field information from macro to micro scales. Such a semi-supervised learning strategy permits network training without complete turbulent flow field data.

Abstract: Various embodiments include techniques for parallel encoding of multiple rows of a media frame. The disclosed video encoder includes multiple controllers, where each controller encodes components, or blocks, included in a different row of a media frame. Each of the controllers encodes the respective blocks of the different rows by sending commands and data to different encoding resources that each perform different encoding functions. The controllers have concurrent and independent access to the encoding resources. As a result, the controllers can access any encoding resource to perform encoding functions without regard to what other encoding resources are performing encoding functions for other controllers. As a result, utilization of encoding resources is increased, and encoding performance is improved, relative to conventional techniques.

Abstract: Disclosed are apparatuses, systems, and techniques that may perform methods of pyramid optical flow processing with efficient identification and handling of object boundary pixels. In pyramid optical flow, motion vectors for pixels of image layers having a coarse resolution may be used as hints for identification of motion vectors for pixels of image layers having a higher resolution. Pixels that are located near apparent boundaries between foreground and background objects may receive multiple hints from lower-resolution image layers, for more accurate identification of matching pixels across different image levels of the pyramid.
