The code in demo.m and demo_images.m perform auto WB using gray-world initial estimation with our rectification function. Lastly, we describe how our framework can leverage a simple illumination estimation method (i.e., gray-world) to perform auto-WB correction that is on a par with the WB correction achieved by the state-of-the-art methods.Д¬heck generateModel.m to re-generate our model. We introduce a new framework that is able to link the nonlinear color-mapping functions directly to the user's selected colors to allow interactive WB manipulation. This approach is an extension to our recent work that proposed a post-capture method for WB correction based on nonlinear color-mapping functions. The goal of this paper is to allow interactive WB manipulation of camera-rendered images. These nonlinear rendering operations make it difficult to change the WB post-capture. This is because the camera hardware has already applied WB to the image and subsequent nonlinear photo-processing routines. Interactively editing WB in camera-rendered images is significantly more challenging.

This is because raw images have no photo-rendering operations applied and photo-editing software is able to apply WB and other photo-finishing procedures to render the final image. Such interactive editing is possible only with images saved in a raw image format. Interactive photo-editing software allows users to manually select different regions in a photo as examples of the illumination for WB correction (e.g., clicking on achromatic objects). WB is applied to remove the color cast caused by the scene's illumination. White balance (WB) is one of the first photo-finishing steps used to render a captured image to its final output.
