Thresholding

Thresholding is a decision-making process used to separate different categories based on specific criteria. Imagine you have a range of colors and want to sort them into two groups: blue and non-blue. You determine a "threshold" that specifies what qualifies as blue. If a color meets this criterion, it’s categorized as blue; if not, it falls into the other group. This concept is widely used in various fields, such as image processing to identify objects, in finance to set investment limits, or in environmental science to determine safe pollution levels, helping simplify complex data into clear, actionable insights.
