3D SIFP (3 dimensional scale invariant features points) can embody the great changes in video both in spatial and temporal domain, which can assure the stability against spatial and temporal attacks. As a result, they enforce the robustness of video watermarking. In this paper, a novel video watermarking scheme exploiting 3D SIFP in DCT (Discrete Cosine Transform) domain is proposed. We establi...

Abstract: Masonry infill is considered as a non-structural element in all type of buildings where masonry use. But, masonry infill walls are mainly used to increase initial stiffness and strength of reinforced concrete (RC) frame buildings. This Open First storey is also termed as “Soft Storey”. The upper storeys have brick infilled wall panels with various opening percentage in it. In many cit...

This paper details the design of an advanced 32 bit 3D frame buffer memory controller for a 3D Graphics Raster Processor called TAYRA [1]. This memory controller is designed to provide a performance of 33 MPixelsls for read and write cycles, 4 GPixelsls for block write, and 16.5 MPixelsls for read, modify, write cycles (with a pixel size of4 bytes). This performance is without any interleaving....

We analyze actual methods that generate smooth frame fields both in 2D and in 3D. We formalize the 2D problem by representing frames as functions (as it was done in 3D), and show that the derived optimization problem is the one that previous work obtain via “representation vectors”. We show (in 2D) why this non linear optimization problem is easier to solve than directly minimizing the rotation...

Abstract: This paper presents a new online preprocessing strategy to detect and discard ongoing bad frames in video sequences. These include frames where an accurate localization between corresponding points is difficult, such as for blurred frames, or which do not provide relevant information with respect to the previous frames in terms of texture, image contrast and non-flat areas. Unlike key...

The construction industry generates a considerable amount of waste. Faced with this undesirable situation, the ready-mix concrete sector, in particular, has invested energy and resources into reusing its own waste in its production process as it works towards the goal of more sustainable construction. This study examines the feasibility of incorporating two types of concrete waste, which curren...
