Abstract: A method to update reference verification information used for electrocardiogram (ECG) signal verification includes: identifying a first ECG signal measured from a user; verifying the first ECG signal by comparing a second ECG signal included in a reference ECG signal set with the first ECG signal; in response to the first ECG signal being successfully verified, setting the successfully verified first ECG signal to be a third ECG signal, and adding the third ECG signal to a verified ECG signal set; and updating the reference ECG signal set by setting the third ECG signal added to the verified ECG signal set to be an additional second ECG signal, based on the reference ECG signal set and the verified ECG signal set.

Abstract: A pose estimation method includes obtains an event stream from an event-based vision sensor configured to capture a target object to which light-emitting devices flickering at a predetermined first frequency are attached, obtains a polarity change period of at least one pixel based on the event stream, generates an image frame sequence using at least one target pixel having a polarity change period corresponding to the first frequency, among the at least one pixel, extracts a feature sequence including feature vectors corresponding to the at least one target pixel, from the image frame sequence, and estimates a pose sequence of the target object by applying the feature sequence to a deep neural network (DNN) model.

Abstract: A method and apparatus for processing sparse points. The method includes determining spatial hierarchical point data based on a key point set and a local point set of a sparse point set, determining relationship feature data by encoding a spatial hierarchical relationship between points of the spatial hierarchical point data, generating a global feature and a local feature of the sparse point set through a conversion operation associated with the relationship feature data, and generating a processing result for the sparse point set based on the global feature and the local feature.
