Therefore, the robustness from compression is tested by MPEG-2 of 6Mbits/sec of 720x480 frame size and the invisibility is proved by measurement of PSNR. Our experimental results show the high quality of the video even if compressed. We consider embedding information to the high quality video streams, such as a DVD, HDTV. The watermarked video frames put in the video MPEG encoder. We select the Y component from the DV signal, and then the watermark information is inserted in all of the Y frames. In the paper, for example, watermark is inserted immediately into the output frame of Digital Video (DV) camcorder. Also the algorithm supports the robustness from the video attacking skills. Our algorithm proposed the specific embedding method in the spatial domain directly rather than the frequency domain. Most previous video watermarking algorithms cannot be supported by real-time processing. Standard method and parabola assumption calculations overestimate the stress, whereas the conical frustum approach gave close results with computer vision method. Stress-strain curves were drawn according to the standard method, parabola assumption, conical frustum assumption, and a newly developed technique. The experimental program was carried out on 15 different cylindrical cohesive soil samples prepared in different moisture contents. Dimensions of the traced sample are measured so that axial and radial strains are calculated in real-time. The time lapse images of the soil sample, which were placed between the backlight and the camera, were digitally acquired. An image acquisition module was integrated to a traditional unconfined compression test device. vision using a specially developed setup and a computer code. This study aims to determine strains directly through computer. In fact, soft clays lose cylinder geometry and deform in an irregular geometry. Alternatively, there are other assumptions, such as parabola and conical frustum. In standard unconfined strength testing, only the axial strain is measured directly, and the radial strain is calculated based on the assumption of uniform deformation. ![]()
