From wikipedia: In photography and optics, vignetting is a reduction of an image’s brightness or saturation toward the periphery compared to the image center.
When presenting a collection of images as a mosaic, the vignetting in the imagery can cause visual discontinuities at the image borders. Here I present a simple strategy to model and correct the vignette in a collection of images.
Step 1: Compute the pixel-wise average for a set of images
I start by creating 2d numpy array of float32 type with the same dimension as our camera. Each [u, v] position in the numpy array is …
