title: How to handle YUV422 (YUYV) image as input of a CNN?
body: <p>I want to feed an image that is stored in the YUV422 (YUYV) format into a CNN. YUV422 means that two pixels are represented by four bytes, basically two pixels share the chroma but have separate luminances.</p>
  
  <p>I understand that for convolutional neural networks the spatiality plays an important role, i.e. that the filters "see" the luminance pixels together with their corresponding chroma pixels. So how would one approach this problem? Or is this no problem at all?</p>
  
  <p>I want to avoid an additional preprocessing step for performance reasons.</p>
