They still use the metric projection approach; nevertheless, the subsets corresponding to these projections have simpler shapes than the classical ones.
In particular this method is similar to that described in Bodnarenko and Chalupa [3] and the only difference is that we have used ChAT immunostaining to obtain two labelled bands corresponding to the projections of cholinergic amacrine cells.
(113) The representation of the object of interest is considered as faithful if the EM images corresponding to its projections are corrected for the effects of the microscope CTF.
By making use of the linear weighting factors corresponding to the projection dimensions, one can project the instantaneous neural frequencies within a moving sliding window (e.g. 1 second width) to the low-encoding projection subspace, enabling the direct visualization of the temporal evolution of dynamic activity patterns throughout the whole experiment.
Then, for each image, we compute a convex hull [23] of the projected vertices (v^{,j}_{i}) to obtain a region corresponding to the projection of the 3D shape on the image ({mathcal {P}}_{j}(S)).
Thereafter, we note, the matrix corresponding to the projection on noise subspace.
The clothoid is calculated according to relation (9) using as value of ℓ the one corresponding to a projection equal to the first column of the Table.
Again, we extract the three 2D canonical views corresponding to the projection of an object, according to the framework described earlier.
In the sagittal plane, concentric radiopaque circles that focus on the axis corresponding to the projection of the capitulum humeri and the medial margin of the trochlea [15, 16] as well as an opaque line along the distal humeral metaphysis are the most important landmarks (Figs. 4, 5).
The full set of tagged particles corresponding to this projection view gives rise to a class average with very good signal for the complex, as well as some extra density, corresponding to the tag, which is distinctive but typically smeared to different extents for different samples due to the flexibility of the tag.
