virtual void | setMinRegionSizeI (int n)=0 |
| : set and get the parameter minRegionSizeI. This parameter is used in the second stage mentioned above. After the EGB segmentation, regions that have fewer pixels then this parameter will be merged into it's adjacent region. More...

virtual void | setSegEgbThresholdI (float c)=0 |
| : set and get the parameter segEgbThresholdI. This parameter is used in the second stage mentioned above. It is a constant used to threshold weights of the edge when merging adjacent nodes when applying EGB algorithm. The segmentation result tends to have more regions remained if this value is large and vice versa. More...

virtual void | setSlicSpixelSize (int n)=0 |
| : set and get the parameter slicSpixelSize. This parameter is used in the first stage mentioned above(the SLIC stage). It describes the size of each superpixel when initializing SLIC. Every superpixel approximately has \(slicSpixelSize \times slicSpixelSize\) pixels in the begining. More...

|
virtual void | setSpatialWeight (float w)=0 |
| : set and get the parameter spatialWeight. This parameter is used in the first stage mentioned above(the SLIC stage). It describes how important is the role of position when calculating the distance between each pixel and it's center. The exact formula to calculate the distance is \(colorDistance + spatialWeight \times spatialDistance\). The segmentation result tends to have more local consistency if this value is larger. More...
