4.8.3 View Menu
The view menu (Figure 29) contains commands that allow the user to visualize various inter-
mediate results.
·
An overlay can be displayed on top of the currently displayed image. The overlay can
be the atlas boundaries (derived from the current data set), iso-angle and iso-
eccentricity ROIs, and specified points in the boundaries or the fovea of a measured
phase image.
·
The phase offset for the rotating-wedge-stimulus case is estimated by calculating a
convolution, which is displayed when the user clicks on “Convolution for Phase-shift
Estimate”. More information on how the estimation algorithm works can be found in
section 6.17.
·
“Image Profile” allows the user to specify a line in the current image. The values in the
image along the line are displayed as a function over distance along the line.
·
By clicking “Measured and Atlas Images”, measured images as well as the correspond-
ing atlases with different resolutions are shown in a figure.
·
The next four commands can be used to show visual areas in the measured phase-
wedge image by overlaying corresponding atlas regions. Results can be displayed for
different resolutions.
·
As mentioned before, an energy function evaluates how well the atlas has been de-
formed. The total energy is a weighted sum, i.e., it has several components. The total
energy as well as the weighted components are stored many times during the minimi-
zation procedure. By clicking on “Energy Series”, the best total energy as well as the
best weighted components are drawn over the number of deformations that have been
done.
