Patent number: 12205249Abstract: Devices, methods, and non-transitory program storage devices are disclosed to provide enhanced synthetic Shallow Depth of Field (SDOF) images, e.g., by using information from images captured by image camera devices and one or more Deep Neural Networks (DNNs) trained to determine how much blurring should be applied to pixels in a mask region (e.g., a region of pixels having an indeterminate foreground or background status and threshold level of gradient magnitude) within an image, given context from surrounding pixels in a reference image and/or an unenhanced synthetic SDOF image. To train the DNNs, various sets of ground truth DSLR images of static scenes, captured at varying aperture settings, may be analyzed.Type: GrantFiled: June 2, 2022Date of Patent: January 21, 2025Assignee: Apple Inc.Inventor: Libin Sun

Patent number: 10713250Abstract: A system and method for identifying whether data skew is causing delays in a map phase and/or a reduce phase of a query of a distributed database. The system and method identify the values of various metrics relating to a database query. These metrics include map phase and reduce phase durations and various related metrics. The system and method gather statistics of multiple queries to determine correlation levels between the metrics and the map phase and reduce phase durations. Based on the statistics, the system and method determine whether one or both of the map and reduce phases for a query/response are taking longer than expected. If the durations are longer than expected, the system identifies the delay as caused by data skew and informs the originator of the query.Type: GrantFiled: November 13, 2015Date of Patent: July 14, 2020Assignee: eBay Inc.Inventors: Tan Chen, Hao Chen, Yong Zhang, Libin Sun, Xin Li
