Abstract: Disclosed are a method and apparatus for recognizing a landmark in a panoramic image. The method includes steps of performing projection transformation on the panoramic image so as to generate a projection image; conducting semantic segmentation on the projection image so as to determine a landmark region and a road surface region; correcting distortion in the landmark region so as to produce a corrected landmark region; and recognizing the landmark in the corrected landmark region.

Abstract: A device authentication method, a service access control method, a device, and a non-transitory computer-readable recording medium are provided. In the device authentication method, an authentication request device issues an authentication request transaction in a distributed ledger, and an authentication response device reads the authentication request transaction in the distributed ledger and performs authentication. Thus, no third-party authentication center or coordinate device is required to participate in an authentication handshake process, thereby reducing deployment overhead of an authentication system and improving efficiency of authentication and access service control.

Abstract: Disclosed are a method and apparatus for processing physiological signals. The method is inclusive of steps of obtaining the physiological signals; grouping the physiological signals based on their sampling frequencies and/or generation mechanisms, so as to acquire grouping results; and compressing, based on the grouping results, each group of physiological signals.

Abstract: An area restricted access system, method, and non-transitory computer-readable storage medium are provided. The system includes an access device and a first service device located in a service area, wherein the access device locates a user device via a first type of wireless signals and obtains a first location parameter. The first service device monitors and locates the user device via a second type of wireless signals and obtains a second location parameter. The area restricted access system generates a modified location parameter based on the first and the second location parameters and determines whether the user device is within or out of the service area based on the modified location parameter. The first service device allows the user device to access the first service device when the user device is within the service area, and forbids the user device to access the first service device when the user device is out of the service area.

Abstract: Disclosed is a method of recognizing a user of at least one mobile device by using an imaging device. The method comprises a first obtainment step of obtaining first positional information of the user of the at least one mobile device by using the imaging device; a second obtainment step of obtaining both second positional information and ID information of the at least one mobile device; a comparison step of comparing the first and second positional information so as to obtain a comparison result; and a determination step of determining, based on the comparison result, whether or not to let the ID information of the at least one mobile device be associated with the user of the at least one mobile device.
