The structural defects in PAN fibers can be reduced significantly by minimizing the inhomogeneity
in solutions due to polymeric chain entanglements, gelation, microbubbles and contaminants.
And, relying on technician's skill opens up various issues including cell contamination by human error, quality inhomogeneity
and et al.
 proposed a biased field estimation FCM(BCFCM) algorithm, which achieves the purpose of compensating the intensity inhomogeneity
by introducing the neighborhood normalization term to modify the objective function.
An unfortunate reality in the modern world is an inhomogeneity
of care options based on location, resources, and other factors.
Spaces of fractional dimensions contain local in-homogeneities in which the fractional dimension of the space differs from the fractional dimension of the vacuum region (which is the neighborhood of the inhomogeneity
, the localization space).
It is then crucial to detect inhomogeneity
in terms of the standards being implemented by the European states, including the member states of the European Union, its economic partners and the candidate states awaiting accession.
Although CHESS has advantages of selectivity for fat and high signal-to-noise ratio (SNR), it is vulnerable to magnetic field inhomogeneity
. STIR is insensitive to magnetic field inhomogeneity
; however, it is not specific for fat.
* using a computational experiment, a preliminary comparative analysis of [S.sub.i] structures was performed to evaluate the degree of magnetic field inhomogeneity
in their working gaps .
 presented a segmentation method for vessel attachment nodules based on integrated active contour model, which can effectively solve the problem of nodules with similar intensity and intensity inhomogeneity
, but this algorithm performance depends largely on the choice of the initial position.
As for ultrasonic image, due to the imaging principle and the properties of object to be tested, the research scholars are often encountered with two major problems, much noise and intensity inhomogeneity
. Noise-resistant function has been added to SDAE when it is designed, to reduce the noise effect.
However, the homogeneity assumption cannot precisely describe the intensity distribution of region with intensity inhomogeneity
. Thus, it often fails to segment the images with intensity inhomogeneity
