How color Calibrate image (jpg/png) with Reference Color in C# using colormatrix

How color Calibrate image (jpg/png) with Reference Color in C# using colormatrix

Asked 2022-Mar-14 at 07:31

I have image which has object for reference. e.g. Rectangle at a particular position.

For (Rectnangle) we already have it's ideal/reference color values e.g. R=255, G=255, B= 255.

Mean RGB of Reactangle is something different e.g. R=200,G=200,B=200.

So there is R=55,G=55,B=55 deviation from ideal/reference color.

How do use color-matrix to fill this gap of color so that I will get calibrated image ?

Please suggest, if any better approch rather than this.

you would calculate the quotient of the two colors, i.e. 255 / 200, and input this in the diagonal values in the color matrix. i.e.

C++ GDI: I am seeking explanation for color matrix such that I can create any color manipulation mask

Asked 2021-Sep-07 at 19:23

I am trying to implement an application that can manipulate the background screen color attributes through a transparent window. Basically trying to recreate Color Oracle. I am progressing here through C++:GDI+ resources. This GDI has a Color Matrix concept. I am able to create filters for greyscale(as shown in the example in the last hyperlink), brightness tweaking, saturation tweaking; However, as advanced use cases such as color blindness filter, blue light filter, contrast tweaks - I am using the hit-n-trial approach, It will be much efficient if anyone can take me in the right direction to learn fundamentals of this color matrix.

Example Matrix is shown below which boosts saturation by a small factor while restricting brightness component.

It will be much efficient if anyone can take me in the right direction to learn fundamentals of this color matrix.

Each color vector is multipled by 5x5 matrix, to make it possible color vector is 5 elements long - the fifth element is a dummy one, this allows to perform additional operations on colors (rotation, scaling, ...).

In your example each color component is multiplied by 1.02f making color brighter, after multiplication - from each color component 0.1 value is subtracted.
