Sign in YCbCr
The YCbCr technique is a way of adjusting and displaying RGB information. In this tutorial you can learn how to create an YCbCr adjuster and add it to your application using Ozeki Camera SDK. You will also find a detailed example code that you can use to create a Windows Forms Application to adjust your webcamera's YCbCr settings. It is very useful if you wish to separate the background from the foreground of an image, e.g. in grey hallways where many clothes are only hardly different from the background.
Important: you should study this article in order to find out how to setup your Windows Forms Application correctly.
Properties
In addition to the methods covered in the previous tutorials this filter has several own functions as well.
Cb: Specifies the Blue chroma value.
Cr: Specifies the Red chroma value.
Y: Specifies the Luma value.
Fillcolor: This method will expect a color defined by YCbCr values to fill out the image with a suitable main color. Note that this method fills out the image and not the background.
