ColourClusteringModes

ColourClusteringModes controls the process of colour categorization. It consists of one or more modes, each mode representing a different way to implement the categorization.

Candidate Mode List

  • CCM_GENERAL_HSV
  • CCM_AUTO

CCM_GENERAL_HSV

This mode clusters the colours using the general algorithm based on HSV (hue, saturation, value). This mode has the following arguments for further customization.

CCM_AUTO

Lets the library choose a mode automatically. Not supported yet.

Setting Methods

As PublicRuntimeSettings Member

ColourClusteringModes can be set dynamically during runtime as a member of FurtherModes, which is a member of PublicRuntimeSettings struct, it is an array with 8 ColourClusteringMode Enumeration items.

Code Snippet in C++

//...other codes
PublicRuntimeSettings* pSettings = new PublicRuntimeSettings;
int errorCode = reader->GetRuntimeSettings(pSettings);
pSettings->colourClusteringModes[0] = CCM_GENERAL_HSV;
reader->UpdateRuntimeSettings(pSettings);
reader->SetModeArgument("ColourClusteringModes", 0, "Sensitivity", "1");
delete pSettings;
//...other codes

Remarks
GetModeArgument and SetModeArgument need to be called for getting and setting Arguments.

JSON Parameter Example

{
    "ColourClusteringModes": [
        {
            "Mode": "CCM_GENERAL_HSV", 
            "Sensitivity": 1
        },
        {

            "Sensitivity": 9
        }
    ]
}

Candidate Argument List

Sensitivity

Sets the sensitivity used for colour categorization. A bigger value means less colours will be clustered as the same colour.
