Event library

Clone the repo:

git clone https://github.com/gianscarpe/event_library.git

Install event_library:

python -m pip install .

python scripts/generate.py input_dir={INPUT_DIR} output_dir={OUTPUT_DIR}
upsample=true extract=true emulate=true representation=voxel  show_debug_images=2

Tree:

+-- inputdir
|	+-- videodir1
|
+-- outputdir
|   +-- videodir1
|     +-- part_0

python scripts/generate.py frames_dir={FRAME_VIDEO_DIR} output_dir={OUTPUT_DIR}
upsample=true extract=false emulate=true representation=voxel  show_debug_images=2

Each video has a imgs directory, where you put the set of frames. Create a fps.txt file in each video directory where you specify the frame-rate of the video as a single integer number (e.g., 30)

Tree:

+-- inputdir
|     +-- videodir1
|         +-- imgs
|         +-- fps.txt
+-- outputdir
|     +-- videodir1
|         +-- part_0

Representation:

• voxelgrid
• constant-count
• raw

extract: if true, extract frames from avi files. To provide frames instead of videos, set 'frame_dir' instead

upsample: if true, upsample frames to higher fps using SuperSloMo model

emulate: if true, create output events files as npy using representation stretegy

show_debug_images: n of image to show for debug at the end of the script
