1.Labeling Policy (instruction included)

1.0 Vegetation

    1. enter photo shop,press alt+F9 to open Action menu,load action script “ps-annotation.atn” selection
    1. open the src url, and press CTRL+F2,a raw mask of vegetation would be generated selection
    1. adjust the selected area by hand(lasso is recommended, just press shift/alt and drag the mouse)
    1. then press CTRL+F3 to generate bitmap, save it by “_t.png” suffix,”DJI_0285_t.png”,e.g.

Annotation example vegetation

Chinese version of annotation instruction

1.1 Building

    1. new a black layer, using polygon lasso to select building and fill it with black
    1. press CTRL+F3 to generate bitmap, save it by “_b.png” suffix,”DJI_0285_b.png”,e.g.

example of annotated result Building

1.2 Other classes

    1. After filled ROI with black, press CTRL+F3 to generate bitmap. Remember to save it by suffix(see Class Definitions above)

2. Directory Naming Policy

/src origin source image

/gt ground truth

/gt_class groundtruth split by classes

/ori annotation raw result(subfolders containing annotated '_t.png', '_b.png', etc. are all here)

/visualization visualization result

you can name your directories arbitrarily. Just keep them corresponding to envs in main.m

3. Scripts

  • script/main.m

    Processing with raw annotated result. You can DIY your ground truth label here.

parameters

visual_mode = 0; % 1 to run gtVisual.m
visual_resizerate=0.25; % downsample rate to accelerate
split_mode = 1; % 1 to run gtSplit.m
split_visualmode = 0;  % 1 to run visualization.m

To visualize the ground truth map.

To generate some split map

After running main.m, you can see the visualization result in/visualization by running this script.

parameters

view_mode = 1; % 0 for automatic, 1 for manual

run this to prepare train.txt,val.txt for training in tensorpack.
