Abstract: An electronic device and a control method using the same are provided. The electronic device may include: a photoplethysmography (PPG) sensor having a plurality of channels arranged isotropically; and a processor configured to: detect a center of gravity of an external force applied to a measurement area of the PPG sensor by an object, based on PPG signals that are detected from the plurality of channels when the object is in contact with the measurement area of the PPG sensor, and generate a control command based on a change in the detected center of gravity.

Abstract: An apparatus and a method for segmenting a steel microstructure phase are provided. The apparatus includes a storage configured for storing a machine learning algorithm and a processing device that segments a microstructure phase using the machine learning algorithm. The processing device is configured to receive label data, to learn a machine learning model by use of the label data as learning data for the machine learning model, and to segment a phase of a steel microstructure image by use of the learned machine learning model.
