'no contour' is a correct and usable phrase in written English.
You can use it when you want to refer to something that is lacking in definition, or is not clearly defined. For example, "The beach had no contour, it was just a flat expanse of sand."
Duanmu (1994) proposes a similar constraint called the No Contour Principle, which disallows contour feature values.
Spot heights in metres give actual altitudes; there are no contour lines.
To measure the electroencephalograph (EEG) responses to the contour without awareness, trials during which a contour was present but not perceived were compared to trials where no contour was present and its absence was correctly indicated.
Schizophrenic patients and healthy controls participated in functional MRI (fMRI) experiments with blocked design using Echo Planner Imaging, in which illusory contour (IC) (Kanizsa's square) and control objects (no contour: NC; real contour: RC) were passively presented.
There were three treatments in the study: (1) plastic-covered ridge with gravel-mulched furrows (T1), (2) plastic-covered ridge with bare furrows (T2), and (3) control (no ridge and no contour furrow) (T3).
Two classes of stimuli were presented to subjects: (1) a field of randomly positioned and oriented Gabor patches (no contour) or (2) the same field of Gabor patches in which a subset of the Gabor patches were oriented in such a way as to give rise to the percept of an ellipse (contour).
But this is no contour-hugging hike: there are a few flat stretches, but mostly when you're not walking steeply uphill, you're walking steeply downhill.
He seems to have no contours or sharp planes.
Here there were no contours, no boundaries, no large objects to occlude or give perspective.
Once the fight was lost, the struggle over, Froberger's underplayed "Ma Mort," in which notes and harmonies bled into each other like heavy oils with no contours, the soul left the body.
If no contours can be found, e.g., for a movement of dot patterns, we can simply rely on the motion discontinuities leading to a coarser localization as the spatial resolution of MSTlModel is less accurate than in V1Model/V2Model due to larger integration steps in the feedforward processing from V1Model to MTModel and MTModel to MSTlModel, respectively.
