pyqt_image_process

Non opencv library implementation. Easy to code in python but super slow.

Enviroment and Dependency

• macOS Monterey 12.6 Apple M1 Max
• Opencv-python 4.5.5 (Rosetta2)
• Pyqt 6.3.1
• matplotlib 3.5.3 (For ploting histogram)
• scipy 1.9.1 (For side window filter, extremly slow if dont use it.)
