What does adaptive thresholding do?

Adaptive thresholding, also called dynamic or local thresholding, establishes the threshold level for determining whether to convert to white or black at a regional level. The region sampled and method of evaluation vary between applications.

Why is global thresholding better than adaptive thresholding?

No, the global thresholding technique is better than adaptive thresholding because it determines the threshold value based on the histogram of the overall pixel intensity distribution of the image whereas adaptive thresholding determines value for each fractional region.

What is the use of adaptive thresholding in image processing?

Like global thresholding, adaptive thresholding is used to separate desirable foreground image objects from the background based on the difference in pixel intensities of each region.

Is local thresholding and adaptive thresholding the same?

In adaptive thresholding, sometimes called local thresholding, our goal is to statistically examine the pixel intensity values in the neighborhood of a given pixel, p.
