WebJan 31, 2024 · Also Note that this is not adding gaussian noise, it adds a transparent layer to make the image darker (as if it is changing the lighting) Adding gaussian noise shall looks like so: import numpy as np import cv2 img = cv2.imread (img_path) mean = 0 var = 10 sigma = var ** 0.5 gaussian = np.random.normal (mean, sigma, (224, 224)) # np.zeros ... WebOct 2, 2024 · Robin's Blog Calculating Rayleigh Reflectance using Py6S October 2, 2024. A user of Py6S recently contacted me to ask if it was possible to get an output of Rayleigh reflectance from Py6S. Unfortunately this email wasn’t sent to the Py6s Google Group, so I thought I’d write a blog post explaining how to do this, and showing a few outputs …
