    摘要: The present invention relates to a full-reference (FR) objective method for assessing perceptual quality of decoded video frames in the presence of packet losses and coding artifacts. A method of assessing perceptual quality is provided. First, a value indicating an amount of distortion in a corresponding portion is accessed. Then, that value is classified as packet-loss distortion or coding-artifact distortion. Next, the classified value is modified to account for visibility differences of the human visual system, based on the classification, and then the modified values are combined for the multiple portions, to form a value indicating a total amount of distortion for the multiple portions.

    摘要: The invention relates to a rotary seal chuck of an optical fiber preform rod deposition lathe, comprising a fixed socket sleeve and a rotary shaft. The fixed socket sleeve is provided with a central hole base. The central hole base bears the rotary shaft through a bearing. An end of the central hole base is connected to an air hose. The rotary shaft is a hollow rotary shaft provided with a through hole. One end of the through hole communicates with the air hose, and the other end of the through hole is provided with a liner tube connecting sealing hole base. A magnetic fluid seal ring is disposed at a joint between an inner side of the rotary shaft and the central hole base of the fixed socket sleeve, to form a rotary dynamic seal. An outer side of the rotary shaft is connected to a rotary driving disk.
