Extraction Process of Aluminium from Bauxite Ore

Alumina Extraction Problem. In the standard Bayer Process for refining bauxite to produce alumina, the dissolution of the alumina in the ore to form sodium aluminate is accomplished in autoclaves under high pressures varying from 70 to 200 pounds per square inch.

Difference between "Edge Detection" and "Image Contours"

Jun 14, 2013· Edges are computed as points that are extrema of the image gradient in the direction of the gradient. if it helps, you can think of them as the min and max points in a 1D function. The point is, edge pixels are a local notion: they just point out a significant difference between neighbouring pixels. Contours are often obtained from edges, but they are aimed at being object contours.

PixInsight Reference Documentation | Debayer

The process of computing the missing color values from a CFA is called color recovery, color reconstruction, or demosaicing. As the most typical CFA pattern is the Bayer pattern, demosaicing is also often referred to as debayering. The Debayer process implements several methods of color recovery for RGB CFA images. The input image can be either ...
