• rawpy ( convert RAW camera file to RGB)
• dtcwt (for wavelets)
• pywi (for wavelets)

Install process (On ubuntu or debian (min buster)):

sudo apt update (adapte for other unix system)
sudo apt install python3 python3-pip git (adapte for other unix system)

for amd64 (classique computer) :

pip3 install astropy numpy tqdm watchdog pyqt5 astroalign opencv-python rawpy python-gettext pywi dtcwt

for arm64/armv8/aarch64 :
