The variation for the FAST keypoint detector is oFAST which adds the feature of orientation and Rotated BRIEF which adds the feature of rotation (it is rotation invariant).
Consistent with the idea that an observer can learn an alternative strategy, it was expected that the option to detect a salient singleton [10], rather than attend to the target-defining feature of orientation, would result in attentional capture by a singleton, such as the large but irrelevant feature that appeared in the display.
These studies show that a desired distribution of connectivity among cells with different orientations determines the features of the orientation map.
Parametric analysis offers useful insights for enhancing the MMFC designs that minimize the adverse effects towards a feature of orientation-independence.
In present paper the authors are focusing on the features of the orientation distribution function (ODF), used to give a probabilistic assessment to the orientation of fibres in fibre reinforced composites.
However, the features of joint orientation distributions are still not easy to describe in practical projects.
At intermediate undercoolings, twinned dendritic samples exhibiting features of mixed orientation are reported.
As a control, the same experiment was repeated using luminance as the discrimination feature instead of orientation, see Figure 3 and Table 2.
This simple model omits prominent features of real orientation-selectivity networks, including nonlinear responses and recurrent connections, but it is able to reproduce several important adaptation phenomena (Figs 4 and 5).
The morphological features and state of orientation of the extruded tubular films were examined by transmission electron microscopy (TEM), high resolution scanning electron microscopy (HSEM), birefringence, wide and small angle X-ray scattering studies (WAXS, SAXS), and linear infra-red (i.r).r
A hallmark feature of the orientation selectivity cortical columnar organization is the presence of pinwheel centers: singularities in the orientation map around which all orientations are represented [45].
