|_. Configuration Parameter |_. Selectable Option/Value |_. Description|
|Input signal frame width     |     |Specify the width of the frame of a single image in the video stream     |
|Input signal frame height     |     |Specify the height of the frame of a single image in the video stream     |

h2. When to use this block?

This block is used concatenate the RGB channels of the video stream from the [[Camera Block]].

h2. How does this block work?

The way the ESP-WHO handle pixel data of an image is different from what Matlab Simulink does. Therefore the [[Camera Block]] transmit the video feed after splitting the image to three channels making it compatible with the Simulink *Computer Vision Toolbox*. After processing the image the three channels could be concatenated using this block.
