 +====== jSLIC - superpixels ======
 +We made a Java-based open source implementation jSLIC - the superpixel clustering with better performance than the original Simple Linear Iterative Clustering. For more info, please see [[http://​​CMP-BIA_tools#​jSLIC_-_superpixels|Fiji wiki]]. ​
 +===== How to use the plugin =====
 +{{ :​plugin:​segmentation:​jslic:​fiji_slic_gui.jpg|jSLIC interface}}
 +As you can see the Interface to the plugin contains a parameters for superpixel configuration and also its final visualisation.
 +==== Configuration ====
 +For the configuration there are only two parameters to be set:
 +  * **Init. grid size** - in general it can be seen as an average superpixels size.
 +  * **Regularisation** - influence the compactness of estimated superpixels. The range is from 0 (very elastic superpixels) to 1 (superpixels are nearly squares). Experimentally,​ we set as optimal value 0.2 for most cases.
 +==== Visualisation ====
 +To show of handle segmentation results we presented a few approaches:
 +  * //Overlap contours// - simply draw the contours on resulting superpixels into the image by chosen colour.
 +  * //Export segments as ROIs// - all superpixels are exported as polygons into the [[http://​​ij/​plugins/​roi-manager-tools/​index.html| ROI Manager]].
 +  * //Show final segmentation//​ - add one more stack and fill each superpixel by a random colour. ​
 +  * //Save segmentation into file// - export the superpixel segmentation into a text file as segmentation matrix with labels.
