摘要： Disclosed is a method of signal detection. A received input signal is divided into a frame unit and each input signal present in a first frame and a second frame is transformed into a frequency signal. Then, first power spectrum information and second power spectrum information are computed utilizing the transformed frequency signal and a delta spectrum entropy value corresponding to a difference of the two computed power spectrum information is obtained. A predetermined input signal is included in a predetermined frame among the input signal after judging through comparing the delta spectrum entropy value with a critical value. Desired signal can be detected in a noisy environment including a noise signal by using the delta spectrum entropy value.

摘要： Provided is a method of recognizing a control command from a finger movement detected from an image capturing apparatus of a mobile device, involving: capturing an image of a finger, determining a contour of the finger from the captured image, determining coordinates of a pointer that corresponds to a region of the finger based on the contour, and recognizing a control command based on a movement direction of the finger, a length of time for which the pointer is positioned on an object, or a change in the contour of the finger.
