White Balancing and dnn modules in OpenCine
Open, NormalPublic


White Balancing is the process of estimating the chromaticity(color) of the illuminant which was used to light the scene. The estimated color of the illuminant can then be used to generate a new image such that it has been taken under standard (D65) illuminant. This can be achieved through an independent gain regulation of the three color signals. This process results in reproducing a white object white (no color cast) irrespective of the color of the illuminant used. This ensures color constancy.

The goal of this task is to explore different variants of the classical AWB (Automatic White Balancing) algorithms currently being used and among which can be implemented in AXIOM Beta. This task is also for implementing the state of the art AWB algorithms for OpenCine which have better results but run time is slow and are computationally bit expensive.

As the resources for AXIOM Beta are limited and the users using the camera are professionals, they have the time to manually dial in the color temperature for the scene. But in post they can import these footage to OpenCine running on a much faster processor and can use any presets (Daylight, Cloudy, Fluorescent..etc) or have the option to set it automatically. This is why I changed the task from "White Balancing Algorithms for AXIOM Beta and OpenCine" to "White Balancing Algorithms for OpenCine".
