Additionally, the lesions were delineated applying three different fixed thresholds.
Five levels were classified with respect to health using fixed thresholds.
Current alarm systems are based on fixed thresholds, generating many false alarms.
Early graph-based methods [24] use fixed thresholds and local measures in finding a segmentation.
The TC is a set of fixed thresholds values obtained during the training.
For volume delineation, we used an adaptive threshold method and three different fixed thresholds for comparison.
The second group (variants II-IV) had fixed thresholds, i.e., ±5%, ±10% and ±20%.
They applied fixed thresholds on the reference signal in order to eliminate the effect of large amplitudes of impulses.
Despite the existence of iterative threshold approaches (see the 'Background' section), fixed thresholds are very common in clinical practice.
Since fixed thresholds are still frequently used [24, 25], we also investigated three different thresholds (see the following paragraphs).
However, in congested networks, fixed thresholds set to high values may lead to excessive route recoveries, which become counterproductive.
