    3D indoor mapping using a RGB-D camera system

    The paper proposes with an application of a RGB Depth (RGB-D) camera system in 3D indoor mapping. In order to reconstruct the 3D model of an indoor space where the robot is located, the RGB-D camera system is installed in the robot frame to continuously capture the separate 2D image frames. All corresponding 2D points between the two consecutive image frames are firstly estimated using a Scan Invariant Feature Transform (SIFT) algorithm.

    Automated architectural reconstruction using refsrence planes under convex optimization

    In this paper, a method for the automated reconstruction of architectures from two views of a monocular camera is proposed. While this research topic has been studied over the last few decades, we contend that a satisfactory approach has not yet been devised. Here, a new method to solve the same problem with several points of novelty is proposed. First, reference planes are automatically detected using color, straight lines, and edge/vanishing...

    channel estimation combined with ici self cancellation  scheme and unscented kaman filter

    A well-known problem of the Orthogonal Frequency Division Multiplexing (OFDM) syste for mobile environment is the fading channel which degrades the system performance. Many methods have been proposed for channel estimation such as LS (Least Square), MMSE (Minimum Mean Square Error), Kalman Filter.…A fading channel with Doppler effect from the moving of receivers degrades system because of complicated changes and hard estimation. That is why...
