Patent number: 11570374Abstract: Devices, methods, and computer-readable media are disclosed, describing an adaptive, subject-aware approach for image bracket selection and fusion, e.g., to generate high quality images in a wide variety of capturing conditions, including low light conditions. An incoming image stream may be obtained from an image capture device, comprising images captured using differing default exposure values, e.g., according to a predetermined pattern. When a capture request is received, it may be detected whether one or more human or animal subjects are present in the incoming image stream. If a subject is detected, an exposure time of one or more images selected from the incoming image stream may be reduced relative to its default exposure time. Prior to the fusion operation, one of the selected images may be designated a reference image for the fusion operation based, at least in part, on a sharpness score and/or a blink score of the image.Type: GrantFiled: June 24, 2021Date of Patent: January 31, 2023Assignee: Apple Inc.Inventors: Hao Sun, Farhan A.

Patent number: 11562470Abstract: Devices, methods, and computer-readable media are disclosed describing an adaptive approach for image bracket selection and fusion, e.g., to generate low noise and high dynamic range (HDR) images in a wide variety of capturing conditions. An incoming image stream may be obtained from an image capture device, wherein the incoming image stream comprises a variety of differently-exposed captures, e.g., EV0 images, EV? images, EV+ images, long exposure (or synthetic long exposure) images, EV0/EV? image pairs, etc., which are received according to a particular pattern. When a capture request is received, a set of rules and/or a decision tree may be used to evaluate one or more capture conditions associated with the images from the incoming image stream and determine which two or more images to select for a fusion operation. A noise reduction process may optionally be performed on the selected images before (or after) the registration and fusion operations.Type: GrantFiled: April 7, 2021Date of Patent: January 24, 2023Assignee: Apple IncInventors: Marius Tico, Alok Deshpande, Anita Nariani Schulze, Hao Sun, Jun Hu, Justin Michael Faryabi-Allen, Morten Poulsen, Tak Shing Wong, Wu Cheng

Publication number: 20220267681Abstract: An improved process and catalyst composition for cracking hydrocarbons in a fluidized cracking process are disclosed. The process employs circulating inventory of a regenerated cracking having a minimal carbon content. The regenerated catalyst comprises a catalyst/additive composition which contains a pentasil zeolite, iron oxide, and a phosphorous compound. In accordance with the present disclosure, the catalyst/additive contains controlled amounts of iron oxide which is maintained in an oxidized state by maintaining low amounts of carbon on the regenerated catalyst inventory. In this manner it was discovered that the catalyst composition greatly enhances the production and selectivity of light hydrocarbons, such as propylene.Type: ApplicationFiled: July 6, 2020Publication date: August 25, 2022Applicant: W.

Patent number: 11207661Abstract: A process for preparing a peptized alumina having increased solids and acid contents and a decreased water content. The process comprising mixing a boehmite or pseudoboehmite alumina and acid with a high intensity, high energy mixer at a ratio of 0.16 to 0.65 moles acid/moles alumina for a time period sufficient to form a substantially free-flowing solid particulate having a solids content of 45 to 65 wt %. When used in catalyst manufacture, peptized alumina produced by the process provides an increased rate in catalyst production and decreased costs due to high solids concentration and the presence of less water to be evaporated.Type: GrantFiled: July 25, 2017Date of Patent: December 28, 2021Assignee: W.R.

Patent number: 11113801Abstract: Devices, methods, and computer-readable media describing an adaptive approach to reference image selection are disclosed herein, e.g., to generate fused images with reduced motion distortion. More particularly, an incoming image stream may be obtained from an image capture device, which image stream may comprise a variety of different image captures, e.g., including “image frame pairs” (IFPs) that are captured consecutively, wherein the images in a given IFP are captured with differing exposure settings. When a capture request is received at the image capture device, the image capture device may select two or more images from the incoming image stream for fusion, e.g., including at least one IFP. In some embodiments, one of the images from the at least one IFP will be designated as the reference image for a fusion operation, e.g., based on a robust motion detection analysis process performed on the images of the at least one IFP.Type: GrantFiled: September 6, 2019Date of Patent: September 7, 2021Assignee: Apple Inc.Inventor: Wu Cheng

Patent number: 11094039Abstract: Devices, methods, and computer-readable media describing an adaptive approach for image selection, fusion, and noise reduction, e.g., to generate low noise and high dynamic range (HDR) images with improved motion freezing in a variety of capturing conditions. An incoming image stream may be obtained from an image capture device, wherein the image stream comprises a variety of differently-exposed captures, e.g., EV0 images, EV? images, EV+ images. When a capture request is received, a set of rules may be used to evaluate one or more capture conditions associated with the images from the incoming image stream and determine which two or more images to select for a fusion operation. The fusion operation may be designed to adaptively fuse the selected images, e.g., in a fashion that is determined to be optimal from a noise variance minimization standpoint. A fusion-adaptive noise reduction process may further be performed on the resultant fused image.Type: GrantFiled: September 6, 2019Date of Patent: August 17, 2021Assignee: Apple Inc.Inventors: Tak Shing Wong, Gijesh Varghese, Farhan A.

Patent number: 11074678Abstract: Embodiments relate to biasing an image noise filter to reduce edge and texture blurring of image data. Pixel values used to determine photometric coefficients for a bilateral filter are modified by offset values. The offset value for a pixel value is determined by applying a high pass filter to the pixel (referred to as the center pixel) and neighboring pixels of the center pixel. By adding the offset value to the center pixel value, the pixel value difference between the neighboring pixels and the center pixel becomes smaller for pixels on the same side of an edge as the center pixel. Thus, pixels on the same side of the edge get more weight in the bilateral noise filter. Conversely, pixels on the opposite side of the edge as the center pixel get less weight in the bilateral filter. As a result, the biased bilateral filter reduces blurring of edges and increases preservation of texture in the image data.Type: GrantFiled: April 24, 2019Date of Patent: July 27, 2021Assignee: Apple Inc.Inventors: Sheng Lin, Wu Cheng, Maxim Smirnov
