This letter presents a steganography method based on a JPEG2000 lossy compression scheme and bit-plane complexity segmentation (BPCS) steganography. It overcomes the lack of robustness of bit-plane-based steganography methods with respect to lossy compression of a dummy image: a critical shortcoming that has hampered deployment in a practical scenario. The(More)
This paper discusses a visual attack to BPCS-Steganography (Bit-Plane Complexity Segmentation-Steganography) and presents a countermeasure. BPCS categorizes each small block within cover images into either a "noise-like region" or an "informative region" by means of the binary-image feature called complexity and replaces noisy blocks with the binary(More)
Our interaction method is a new technology allowing users to intuitively control moving drones in a three dimensional world. We have designed a prototype to implement the technology for controlling a multi-copter. Our purpose is to handle remote machinery and materials freely with intuitive control, and to expand spatial mobilization capabilities. We(More)
