The two arguments low_threshold and high_threshold allows us to isolate the adjacent pixels that follow the strongest gradience. If the gradient is larger than the upper threshold, then it is identified as an edge pixel.

WebThe edges between ‘High’ and ‘Low’ thresholds are classified as edges only if they are connected to a sure edge otherwise discarded. Let’s take an example to understand Here, A and B are sure-edges as they are above ‘High’ threshold. Similarly, D is a sure non-edge. WebJun 22, 2024 · Accepted Answer.
