The strong inter-channel cross correlation between stereo received signals creates a problem of non-unique solutions for stereo echo cancellation. To avoid this problem, the addition of inaudible non-linearly filtered received signals to themselves was proposed. However, the convergence of misalignment is still slow even when the affine projection algorithm is used, since strong inter-channel c...

This paper proposes an affine projection algorithm (APA) with variable projection order using the mean-square error (MSE) criterion. The proposed algorithm determines the projection order at every iteration to use it in the update equation of the proposed APA. The MSE criterion is employed to decide the projection order reasonably. Moreover, this algorithm checks the steady-state condition to c...

To resolve the problems that the local motions reduce the global motion estimation accuracy and traditional Gary Projection Algorithm could not deal with rotation motion, a real-time electronic image stabilization motion estimation method based on Fast Sub-block Gray Projection Algorithm is proposed. In the method, each image is divided into a number of sub-blocks, and sub-blocks are sifted acc...

The analysis of repeats in the DNA sequences is an important subject in bioinformatics. In this paper, we propose a novel projection-assemble algorithm to find unknown interspersed repeats in DNA sequences. The algorithm employs random projection algorithm to obtain a candidate fragment set, and exhaustive search algorithm to search each pair of fragments from the candidate fragment set to find...

Introduction: Iterative reconstruction techniques provide better image quality and have the potential for reconstructions with lower imaging dose than classical methods in computed tomography (CT). However, the computational speed is major concern for these iterative techniques. The system matrix calculation during the forward- and back projection is one of the most time- cons...

The shear reinforcement of dual-anchorage (SRD) is used to enhance the safety reinforced concrete structures in construction sites. In SRD, welding create reinforcement, and after production, a quality inspection bead required. Since SRD inspected for by measuring both horizontal vertical lengths, it necessary obtain this information inspection. However, difficult inspect beads using existing m...
