lowerthreshold
Lowerthreshold refers to a minimum boundary used in thresholding operations to classify or filter data by magnitude. It serves as a cutoff value such that measurements, signals, or features below the threshold are treated differently (often suppressed or set to a baseline), while those at or above the threshold proceed to further processing. In some contexts a corresponding upper threshold defines a range or dead zone between the two bounds.
Applications and context vary by field. In image processing, a lower threshold is commonly used in binarization
Choosing a lower threshold depends on the data characteristics, the desired sensitivity, and the noise level.
