  • Publication number: 20240141505
    Abstract: A gas permeable metal with a porosity gradient and a method of manufacturing the same are provided. A second lamination layer and a third lamination layer are respectively connected to two opposite sides of a first lamination layer. A pore diameter of the first lamination layer is larger than that of the second lamination layer. Thereby while being applied to molds, a mold cavity is mounted in the second lamination layer with smaller pore diameter so that products formed have fine and smooth surfaces. The arrangement of the first lamination layer with larger pore diameter is used for effective escape of gas generated during product production process. According to production requirements for products, a pore diameter of the third lamination layer can be adjusted to be not larger than that of the first lamination layer. Thus mechanical strength and gas exhaust capacity can be balanced.

    Abstract: Various schemes pertaining to pre-encoding processing of a video stream with motion compensated temporal filtering (MCTF) are described. An apparatus determines a filtering interval for a received raw video stream having pictures in a temporal sequence. The apparatus selects from the pictures a plurality of target pictures based on the filtering interval, as well as a group of reference pictures for each target picture to perform pixel-based MCTF, which generates a corresponding filtered picture for each target picture. The apparatus subsequently transmits the filtered pictures as well as non-target pictures to an encoder for encoding the video stream. Subpictures of natural images and screen content images are separately processed by the apparatus.
