Identification of homogeneous subsets of images in a macromolecular electron microscopy (EM) image data set is a critical step in single-particle analysis. The task is handled by iterative algorithms, whose performance is compromised by the compounded limitations of image alignment and K-means clustering. Here we describe an approach, iterative stable alignment and clustering (ISAC) that, relying...
In single particle analysis, two-dimensional (2-D) alignment is a fundamental step intended to put into register various particle projections of biological macromolecules collected at the electron microscope. The efficiency and quality of three-dimensional (3-D) structure reconstruction largely depends on the computational speed and alignment accuracy of this crucial step. In order to improve the...
This paper introduces a new algorithm in Ereka-147 digital audio broadcasting (DAB) symbol timing offset estimation. The proposed algorithm performs robust operation and low complication in symbol timing offset estimation. The performance of this algorithm is carried out under AWGN and multipath fading channel.
