Experimental particle’s shapes reconstructions from their interferometric images using the Error-Reduction algorithm
نویسندگان
چکیده
The Error-Reduction algorithm is tested to reconstruct the exact 2D-shape of irregular rough particles from their experimental interferometric images. are “programmable” generated with a digital micromirror device. method first applied centrosymmetric particles, and then non-centrosymmetric where twin image problem brings additional difficulty.

Radio Interferometric Calibration Using The SAGE Algorithm
Radio Interferometry is an essential method for astronomical observations. Self-calibration techniques have increased the quality of the radio astronomical observations (and hence the science) by orders of magnitude. Recently, there is a drive towards sensor arrays built using inexpensive hardware and distributed over a wide area acting as radio interferometers. Calibration of such arrays poses...
متن کاملDimensionality Reduction and Classification of Hyperspectral Images using Genetic Algorithm
This paper presents genetic algorithm based band selection and classification on hyperspectral image data set. Hyperspectral remote sensors collect image data for a large number of narrow, adjacent spectral bands. Every pixel in hyperspectral image involves a continuous spectrum that is used to classify the objects with great detail and precision. In this paper, first filtering based on 2-D Emp...
متن کاملFace Images Dimension Reduction using Wavelets and Decimation Algorithm
This paper demonstrates a novel lower dimension multi resolution analysis technique to represent facial images using wavelet transform and decimation, which alleviate heavy computational load, reduce noise, produce a representation in low frequency domain and hence make the facial images less sensitive to facial expressions and small occlusions. All coefficients of wavelet transform do not have...
متن کاملImproved digital holographic reconstruction algorithm for depth error reduction and elimination of out-of-focus particles.
The digital holography has immense potential related to many applications of science and engineering. It has many advantages compared to conventional holography i.e. characterization of online dynamic phenomena and imaging in small scale microscopic systems. However, its primary limitation is the size of sensors and number of sensors compared to the conventional holographic plate. The critical ...
متن کاملAnalysis of Interferometric Images Using the Hough Transform
The Hough transform is adapted to determine fringe spacings and orientations of noisy interferometric images consisting of one or more superimposed Young’s fringe patterns. These measurements are used to calculate the deformation of concrete under stress, and are part of an investigation into the impact of traffic flow on bridge stability. Introduction: A specklegram is a double-exposed negativ...
