A method and a wearable communication system for personal face-to-face and wireless communications in high noise environments are provided. A noise cancellation device (NCD) operably coupled to a wireless coupling device (WCD) includes a speech acquisition unit, an audio signal processing unit, one or more loudspeakers, and a communication module. The NCD receives voice vibrations from user speech via a contact microphone and a second microphone and converts the voice vibrations into an audio signal. The NCD processes the audio signal to remove noise signals and enhance a speech signal contained in the audio signal. A loudspeaker emits the speech signal during face-to-face communication. The NCD transmits the speech signal to a communication device via the WCD and receives an external speech signal from the communication device during wireless communication. With the NCD, the signal intelligibility and signal-to-noise ratio can be improved, for example, from &#x2212;10 dB to 20 dB.

Wearable communication system with noise cancellation

A color correction system includes an identical first color chart (FCC) and a second color chart (SCC), and a color correction unit (CCU). The FCC and the subject are positioned in view of a source image capture device (SICD) at a source location. The SCC and a display unit are positioned in view of a destination image capture device (DICD) at the destination location. The SICD captures and transmits source image content (SIC) of the subject and the FCC to the CCU at the destination location via a network. The DICD captures destination image content (DIC) of the SCC and the SIC displayed on the display unit. The CCU generates calibration parameters by comparing the FCC extracted from the SIC and/or the DIC, with the SCC extracted from the DIC, and corrects the SIC of the subject and gamma parameters on the display unit using the generated calibration parameters.
