Color imaging in machine vision: how to choose the right

网页Bayer cameras rely on a predefined pattern of color filters which overlay the pixels on a camera’s imager. Calculating the red, green, and blue (RGB) color value for any specific pixel requires a process of interpolation which looks at surrounding pixels to estimate the values for the two colors not captured by that pixel’s filter.

What Is the Bayer Process? (with picture) AllTheScience

网页2023年7月18日  The Bayer process is an industrial process by which bauxite is purified into alumina, or aluminum oxide. Named for Karl Bayer, who developed it in the late 19 th century, this process is an essential intermediate step in the production of aluminum metal. Alumina is produced through a series of controlled chemical reactions from bauxite, a
