Experimental results demonstrate that the proposed method avoids over-segmentation or ill-segmentation caused by uneven illumination, and the industrial application reveals the reliability of bubble size estimation.
For over-segmentation caused by watershed, we also investigated different noise reduction technologies.
The major limitation of these methods is the lower segmentation accuracy caused by the over-segmentation methods.
b Axial enhanced CT image of a 47-year-old man depicts segmentation challenges caused by ill-defined and non-continuous borders found near the liver dome (arrows).
At higher cutting speeds chip segmentation is caused by thermoplastic shear localisation at the primary shear zone causing high temperature rise and rapid tool wear close to the cutting edge of the tool.
The segmentation phenotypes caused by Smad8 depletion were specific, as they were rescued by co-injection of human Smad1 mRNA (Figure 7E 7E″).
RPE segmentation errors caused by such effects can be handled by more sophisticated algorithms [ 44].
These unsuccessful segmentations are caused by the complexity and similarity of the background.
The unsuccessful segmentations are caused by the fact that it is not enough to distinguish the objects from the background by only considering a single image.
In general, the automated segmentation is one of the most difficult tasks in the image analysis, because a false segmentation will cause degradation of the measurement process and therefore the interpretation may fail [7].
For the conventional technique, the BER increases significantly and the segmentation process causes a considerable loss of the watermark information for images from databases DB2 and DB3.
