Some time ago to do a semantic segmentation of the data set, and finally Mark all done today, batch modify a previous blog how to write a batch file to convert json into their desired label pictures, after the conversion is complete, I want to use the most common semantic segmentation training model for training, but found that there need to write the corresponding color of the label rgb value, so I find a bit on the internet and found no explanation, then himself hands looking at the function of producing color final in front of this function to add an input rgb value, you get the results you want.
First results posted output terminal:
