Patent number: 11113802Abstract: An adaptive approach to image bracket determination and a more memory-efficient approach to image fusion, which are designed to generate low noise and high dynamic range (HDR) images in a wide variety of capturing conditions, are described. An incoming preview image stream may be obtained from an image capture device. When a capture request is received, an analysis may be performed on an image from the preview image stream that has a predetermined temporal relationship to the image capture request. Based on the analysis, a set of images (and their respective capture parameters, e.g., exposure time) may be determined for the image capture device to capture. As the determined set of images are captured, they may be registered and fused in a memory-efficient manner that, e.g., places an upper limit on the overall memory footprint of the registration and fusion operations—regardless of how many images are captured in total.Type: GrantFiled: September 9, 2019Date of Patent: September 7, 2021Assignee: Apple Inc.Inventors: Hao Sun, Giancarlo Todone, Farhan A.

Patent number: 11094040Abstract: A noise detection method for time-series vegetation index (TSVI) derived from remote sensing images. Firstly, unit root test is used to classify observation values of each pixel into a stationary series or a non-stationary series; for the non-stationary, an appropriate mathematical model is used to model discrete TSVI, then differences between actual observation values and prediction values of the model are calculated and recorded as a deviation. As the deviation has removed seasonal components, the non-stationary series is transformed into a stationary series. For a stationary series or deviation data, noise detection is performed based on the assumption that observation values are distributed within a certain range around mean values; then model fitting and noise detection are iteratively carried out with remained observation values—until the iterations reached the maximum number or no noise is detected at one iteration.Type: GrantFiled: November 19, 2019Date of Patent: August 17, 2021Assignee: ZHEJIANG UNIVERSITY OF TECHNOLOGYInventors: Wei Wu, Jiancheng Luo, Ying Shen, Tingting Chen, Weiwei Ge, Zhenqian Chen, Liegang Xia
