@LogWell found a solution how to prepare DATASETS. You can use following files structure:


where datasets/CIHP/images/0002190.png - it’s a source image

datasets/CIHP/list/img_list.txt contain following data: 0002190.png

and datasets/CIHP/images/tool/logwell_script.m - it’s a MATLAB script for prepare edges and labels:

close all;
fclose all;
imglist = '../list/img_list.txt';  % 00000.png
list = textread(imglist, '%s');

for i = 1:length(list);
    imname = list{i};
    instance_map = imread(fullfile('../images', imname));
    instance_contour = uint8(imgradient(rgb2gray(instance_map)) > 0);
    imwrite(instance_contour, fullfile('../edges', imname));
    imwrite(instance_contour, fullfile('../labels', imname));

Just run this script using command like: /opt/MATLAB/R2018b/bin/matlab -nodisplay -nojvm -nosplash -nodesktop -r "try, run('tool/logwell_script.m'), catch, exit(1), end, exit(0);"

and after that you can run python for get segmented images.

I write a python script to prepare the data, maybe you want to try it

@qzane Thank you for your python script. But this only generates the edges file and the respective blank(black) images. Do you have a python script to generate labels as well?

@gayalkuruppu I don’t think you need labels to get the correct output. I created a folder with custom images, ran the python script that was linked to in a previous comment ( and I saved it as with

python custom_dataset/CIHP/images CIHP

and it created a new folder within datasets/ called CIHP (it’ll be named whatever you use as the last argument in the previous python command).

The new folder has the structure

├─ datasets/
│  ├─ CIHP/
│  │  ├─ edges/
│  │  │  ├─ image0.png
│  │  │  ├─ image1.png
│  │  ├─ images/
│  │  │  ├─ image0.png
│  │  │  ├─ image1.jpg
│  │  ├─ list/
│  │  │  ├─ val_id.txt
│  │  │  ├─ val.txt

and then I was able to run python and see the results in CIHP_PGN/output/cihp_parsing_maps/
