The feature images which have been decomposed can be named as monogenic binary coding amplitude image JPG - A, monogenic binary coding phase image
JPG-[phi], and monogenic binary coding orientation image JPG-[theta].
The estimated field map is compared to the measured field map, i.e., the phase image
, and the difference, the error, is used to update the initial guess.
(a) The phase image
of microstep measured by DDIPHM with BEMD.
To demonstrate the advantages and compare the unwrapping speed of the dual-wavelength DHM and traditional single-wavelength DHM, a 632.8 nm wrapped phase image
is chosen to obtain the final height distribution by unwrapping procedure, which is named the quality-guided phase unwrapping algorithm.
we focus on the role of susceptibility, and use the original phase image
both by itself and as a means of altering the contrast in the magnitude images, we refer to this method as SWI.
The noncontrast enhanced (NC) phase image
is obtained from scans before injection and three more phases' images are scanned at different times after contrast injection, including arterial (ART) phase, portal venous (PV) phase, and delayed (DL) phase, scanned at 25~40s, 60~ 75 s, and 3~5 minutes after contrast injection, respectively.
Then, phase angles representative of the TAC behavior is extracted from these components, and a map (phase image
) representing the ventricular contraction sequence is constructed .
Using a laser and interference microscope, the following morphological properties of erythrocytes were determined: the optical path difference (OPD), the surface area of the erythrocyte phase image
(S), the physical height (Z), and phase volume of erythrocytes (V) .
This reconstruction wavefront consists of real and imaginary parts, from which a 2D amplitude image (similar to what would be observed in a conventional light microscope) and a 2D phase image
are generated .
This image clearly shows that the vapor phase region in the UV image is not detected by the visible light shadow imaging technique used to generate the liquid phase image
, implying that the vapor phase region of the vaporized spray can be captured successfully by using UV light and an image intensifier.
The blocks are concatenated to create a large "phase image
" with their relative neighbors kept.
