  • Patent number: 10997746
    Abstract: Feature descriptor matching described herein may include receiving a first input image and a second input image. A feature detector may detect features from the first and second input images. A descriptor extractor may learn local feature descriptors from the features of the first and second input images based on a feature descriptor matching model trained using a ground truth data set. The descriptor extractor may determine a listwise mean average precision (mAP) rank of a pool of candidate image patches from the second input image with respect to a queried image patch from the first input image based on the feature descriptor matching model, the first set of local feature descriptors, and the second set of local feature descriptors. The descriptor matcher may generate a geometric transformation between the first input image and the second input image based on the listwise mAP and a convolutional neural network.

  • Patent number: 10873885
    Abstract: A wireless communication system may support two types of networks, such as a 4th-Generation (4G) network and a 5th-Generation (5G) network. The 4G network is accessed through Long-Term Evolution (LTE) base stations. The 5G network is accessed through New Radio (NR) base stations. During idle mode, a communication device may scan 5G RF frequencies to determine whether a 5G signal is available and whether to display a 5G network symbol in the status bar of the device. The communication device is configured to detect conditions indicating whether a user of the device is likely viewing the device and/or the display of the device. If it is unlikely that the user is viewing the device or its screen, RF frequency scanning is paused to reduce power consumption and the currently displayed network symbol is maintained until RF frequency scanning is resumed.
