Abstract: A synthetic image of a target is generated and combined with an image of a background to generate a synthetic training image for the target. The synthetic image of the target is inserted as a patch into the background image. The synthetic training image for the target is labeled as including a depiction of the target based on insertion of the synthetic training image into the background image. The location in which the target is depicted in the synthetic training image is automatically determined based on the location into which the synthetic image of the target is inserted into the background image.

Abstract: A system and method for securing backscatter communication. In one embodiment, a backscatter communication system includes a reader. The reader is configured to receive backscatter transmissions. The reader includes a transmitter configured to emit a radio frequency signal to induce backscatter communication. The transmitter includes a continuous wave (CW) carrier signal generator and a noise signal generator. The CW carrier signal generator produces a CW carrier signal. The noise signal generator generates a noise signal. The transmitter is configured to combine the CW carrier signal and the noise signal, and to transmit the combined signal to induce backscatter communication.
