  • Publication number: 20250117909
    Abstract: In some embodiments, a method receives a first image and a second image for a comparison of film grain. The first image and the second image are converted from a spatial domain to a frequency domain to generate a first frequency domain representation for the first image and a second frequency domain representation of the second image. The method compares a first distribution of frequency components from the first frequency domain representation to a second distribution of frequency components from the second frequency domain representation. A score for an assessment of differences of the film grain in the first image and the second image is generated based on the comparing.

  • Publication number: 20250116001
    Abstract: A semiconductor processing chamber may include a pedestal configured to support a substrate during a plasma-enhanced chemical-vapor deposition (PECVD) process that forms a film on a surface of the substrate. The chamber may also include one or more internal meshes embedded in the pedestal. The one or more internal meshes may be configured to deliver radio-frequency (RF) power to a plasma in the semiconductor processing chamber during the PECVD process. An outer diameter of the one or more internal meshes may be less that a diameter of the substrate. The chamber may further include an RF source configured to deliver the RF power to the one more internal meshes. This configuration may reduce arcing within the processing chamber.

  • Publication number: 20250106408
    Abstract: In some embodiments, a method analyzes flagged locations from a plurality of locations in an encoding of a video to form a cluster of locations. Draft micro-chunk boundaries for the cluster are determined based on searching for a first start location and a first end location in the encoding. The method searches in a first search range before the first start location and a second search range after the first end location for a second start location in the first search range and a second end location in the second search range. The second start location and the second end location form a micro-chunk. An encoding parameter set is determined for the micro-chunk formed by the second start location and the second end location based on content characteristics of the micro-chunk. The method uses the encoding parameter set to encode the micro-chunk for insertion in the encoding of the video.
