ContrastThreshold ContrastThreshold VPARAMETER 303 Defines the minimum contrast needed for an edge to be detected in the input image and used for arc computation. This threshold is expressed in terms of a step in greylevel values. Except when ContrastThresholdMode is set to hsContrastThresholdFixedValue, the property is read-only. Syntax Micro V+ VPARAMETER (sequence_id, tool_id, 303, index_id, object_id) = value value = VPARAMETER (sequence_id, tool_id, 303, index_id, object_id) V+ VPARAMETER (sequence_id, tool_id, 303, index_id, object_id) $ip = value value = VPARAMETER ($ip, sequence_id, tool_id, 303, index_id, object_id) Type Long Range Minimum: 1 Maximum:
255 Remark(s) By default, the tool selects a ContrastThresholdMode based on image content to provide flexibility to variations in image lighting conditions and contrast. Adaptive threshold modes are generally recommended. A fixed-value contrast threshold should only be used when adaptive values do not provide satisfactory results.
