WebOr, you can create external hysteresis by applying positive feedback to a comparator. Because positive feedback guarantees a fast output transition from one state to the other, the comparator output spends a negligible amount of time in the indeterminate state. Figure 3. Indeterminate and rapidly changing outputs of comparators without hysteresis. WebHere, the first element of the tuple determines the lower threshold, while the second element determines the upper threshold. ... Threshold or hysteresis thresholds for the contrast of the object in the image and optionally minimum size of the object parts. Default value: 30. Suggested values: 10, 20, 30, 40, 60, 80, 100, 120, 140, 160.
