  • Patent number: 11979593
    Abstract: Method and apparatus for affine CPMV or ALF refinement are mentioned. According to this method, statistical data associated with the affine CPMV or ALF refinement are collected over a picture area. Updated parameters for the affine CPMV refinement or the ALF refinement are then derived based on the statistical data, where a process to derive the updated parameters includes performing multiplication using a reduced-precision multiplier for the statistical data. The reduced-precision multiplier truncates at least one bit of the mantissa part. In another embodiment, the process to derive the updated parameters includes performing reciprocal for the statistical data using a lookup table with (m?k)-bit input by truncating k bits from the m-bit mantissa part, and contents of the lookup table includes m-bit outputs. m and k are positive integers.

  • Patent number: 11942750
    Abstract: A laser inspection system is provided. A laser source emits a laser with a first spectrum and the laser is transmitted by a first optical fiber. A gain optical fiber doped with special ions is connected to the first optical fiber, and a light detector is provided around the gain optical fiber. When the laser with the first spectrum passes through the gain optical fiber, the gain optical fiber absorbs part of the energy level of the laser with the first spectrum, so that the laser with the first spectrum is converted to generate light with a second spectrum based on the frequency conversion phenomenon. The light detector detects the intensity of the light with the second spectrum, so that the power of the laser source can be obtained.
