Publication number: 20240168954Abstract: Techniques and solutions are described for implementing virtual table schemas. A virtual table schema includes a logical pointer that is used to target a table that includes data and is defined according to the virtual table schema. Values assigned to the logical pointer can be used to target tables at different locations, such as in-memory storage or in dynamic storage of a database management system. The dynamic storage includes an in-memory buffer cache and persistent storage. The logical pointer can be updated to point to the in-memory storage or the dynamic storage, including based on use statistics. Similarly, a table having data for the virtual table can be transitioned between the in-memory buffer cache and the persistent storage, including based on use statistics for the virtual table. A value for the logical pointer can be updated when the table is transferred between the in-memory buffer cache and the dynamic storage.Type: ApplicationFiled: January 29, 2024Publication date: May 23, 2024Applicant: SAP SEInventors: Ruediger Karl, Mihnea Andrei, Juchang Lee, Stefan Baeuerle, Seyeong Bae, Joo Yeon Lee

Patent number: 11741582Abstract: Techniques for enhancing an image are described. For example, a lower-resolution image from a video file may be enhanced using a trained neural network applying the trained neural network on the lower-resolution image to remove artifacts by removing artifacts by generating, using a layer of the trained neural network, a residual value based on the proper subset of the received image and at least one corresponding image portion of a preceding lower resolution image in the video file and at least one corresponding image portion of a subsequent lower resolution image in the video file, upscale the lower-resolution image using bilinear upsampling, and combine the upscaled received image and residual value to generate an enhanced image.Type: GrantFiled: January 4, 2022Date of Patent: August 29, 2023Assignee: Amazon Technologies, Inc.Inventors: Silviu Stefan Andrei, Nataliya Shapovalova, Walterio Wolfgang Mayol Cuevas

Patent number: 11425448Abstract: An input video stream corresponding to input video content may be received over one or more networks. The input video stream may include a first image frame. An input visual feature of the first image frame may be matched to a reference visual feature of a reference image. The reference image may have a higher image quality than the first image frame. A replacement visual feature may be generated for the input visual feature. The replacement visual feature may be generated based at least in part on the reference visual feature. An enhanced image frame corresponding to the first image frame may be generated by at least replacing the input visual feature in the first image frame with the replacement visual feature. An enhanced video stream may be provided. The enhanced image frame may be a substitute for the first image frame in the enhanced video stream.Type: GrantFiled: March 31, 2021Date of Patent: August 23, 2022Assignee: Amazon Technologies, Inc.Inventors: Tejas Shamrao Khot, Nataliya Shapovalova, Silviu Stefan Andrei, Walterio Wolfgang Mayol Cuevas, Wasiq Bokhari

Patent number: 11017506Abstract: Techniques for enhancing an image are described. For example, a lower-resolution image, for example from a video file, may be enhanced using a trained neural network by applying the trained neural network to enhance a middle lower-resolution image of a plurality of lower-resolution images using a generator with filters of a generative adversary network. In some examples, a plurality of sequential feature processing acts are performed on the lower-resolution images to generate a residual which is added to a filtered version of one of the lower-resolution images to generate an enhanced image.Type: GrantFiled: May 3, 2019Date of Patent: May 25, 2021Assignee: Amazon Technologies, Inc.Inventors: Walterio Wolfgang Mayol Cuevas, Silviu Stefan Andrei, Nataliya Shapovalova
