    Abstract: Aspects of the disclosure provide a method and an apparatus for monitoring a paging occasion (PO). For example, the apparatus can include receiving circuitry and processing circuitry. The receiving circuitry can be configured to receive an SS block burst set including a sequence of SS blocks that are each associated with a paging early indicator indicating whether a paging massage is presented in at least one PO that comes later than the SS block burst set. The processing circuitry can be configured to monitor the at least one PO for the paging message when the paging early indicator indicates that the paging message is presented in the at least one PO, and enter a sleep state without monitoring the at least one PO when the paging early indicator indicates that the paging message is not presented in the at least one PO.

  • Publication number: 20220005202
    Abstract: The invention provides an image segmentation method and an electronic device. The image segmentation method includes the following steps. Regression analysis is performed on a first gray-scale image to obtain a residual image having an object backbone area. A pixel value of each pixel in the object backbone area is defined as an average gray-scale value of the object backbone area in the residual image, and a second gray-scale image having the object backbone area is generated. It is recursively determined whether a residual polarity of each adjacent pixel adjacent to edge pixels of the object backbone area in the residual image is the same as a residual polarity of the corresponding edge pixel, and whether a pixel value of each adjacent pixel is greater than a first threshold, so as to expand the object backbone area in the second gray-scale image, which is extracted as a target object.
