Kontext:
Region merging will now be discussed. The ***bias or illumination field estimation*** and
correction at step 715, the region splitting at step 717, the principal component decomposition at step 719, and the Gibbs random field based segmentation relaxation at step 721 will be familiar from the description already given. While it is possible to optimize the Bhattacharyya threshold T, a more computationally efficient technique is constrained merging. The constrained statistical region merging via the local Bhattacharyya distance, shown at step 723, is based on the principle that regions should preferably be merged if their compactness is reduced and should preferably not be merged if their compactness is increased.
"illuminiation field" habe ich als "Lichtfeld" gefunden und so auch vorstehend schon verwendet, aber "bias (field)" ist noch nicht vorgekommen

Discussion
Als Bias [}, engl. für Schräge, Vorurteil] bezeichnet man in der Elektronik eine konstante Größe, die den eigentlichen Nutzsignalen überlagert wird.
In electrical engineering, the term bias has the following meanings: A systematic deviation of a value from a reference value. The amount by which the average of a set of values dep
