Rectangle Detection in An Image

What would be the best method to preprocess this image to help isolate the two wooden boards more? I will need to place boundary boxes around them everntually too. Is there any good method of identifying boards like this that may be a different color?

i did not try yet, but if you can try to convert the image to grayscale by using the max() function along the 3rd dimension, in this case the color is red and blue what should work fairly well here
