Research Article A Novel Blind Separation Method in

The key point of the method is the formulation of the new matrix which forms a generalized permutation of the original mixing matrix. Since the lowest entropy is closely associated with the smooth degree of source images, blind image separation can be formulated to an entropy minimization problem by using the property that most of neighbor

Blind Compressive Sensing Dynamic MRI IEEE

2013-3-27 · Abstract: We propose a novel blind compressive sensing (BCS) frame work to recover dynamic magnetic resonance images from undersampled measurements. This scheme models the dynamic signal as a sparse linear combination of temporal basis functions, chosen from a large dictionary. In contrast to classical compressed sensing, the BCS scheme simultaneously estimates

Blind image separation using pyramid technique

Signal and image separation is an important processing step for accurate image reconstruction, which is increasingly applied to many medical imaging applications and communication systems. Most of the conventional separation approaches are based on frequency domain and time domain. These approaches, however, are sensitive to noise and thus often produce undesirable results.

Blind separation of electron paramagnetic resonance

2010-5-1 · This paper presents a method for the blind separation of Electron Paramagnetic Resonance (EPR) spectroscopy signals that can aid in the detection of free radicals in living organisms. Observed EPR signals are often mixtures of source signals that are approximately “sparse”, with a small number of narrow segments of the signal much larger

Anechoic Blind Source Separation Using Wigner Marginals

2020-11-5 · magnetic resonance imaging, where time shift occur naturally due to hemodynamic delays (Mørup et al., 2008). The major part of previous work on anechoic mixtures has considered under-determined (over-complete) source separation problems (m ≤n), where the sources outnumber the dimensions of the available data.

Blind image separation using pyramid technique

2018-5-30 · separation problem. The method in [14] considers a nonlinear real-life mixture of document images that occur when a page of a document is scanned and the back page shows through. It used a separation method based on the fact that the high-frequency components of the images are sparse and are stronger on one side of the paper than on the other one.

258 IEEE TRANSACTIONS ON MEDICAL IMAGING, VOL.

2015-6-9 · Separation of signals specific to dynamic structures belongs to the category of blind source separation. It is an underdetermined problem with many possible solutions. Existing separation methods select the solution that best matches their additional assumptions on the source model. We propose a novel blind source separation method

Special Issue "Magnetic Nanoparticles: Novel

Drug release test shows that AC magnetic field can be used as switch and accelerator for NPs to release drugs. In addition, thrombolytic efficiency is nearly four times that of pure urokinase. This indicates that the coupling magnetic field may be a promising method to improve thrombolytic effect of the prepared magnetic carrier drug conjugates.
