Descriptors

Hi Guys!

I am writing some code for matching descriptors using BRIEF.

My code till now:

grid = Gray.(hcat(imgColorG, imgGray))
offset = CartesianIndex(0, size(imgColorG, 2))
map(m -> draw!(grid, LineSegment(m[1], m[2] + offset)), matches)
grid

I am getting this warning:

WARNING: one(ColorTypes.Gray{FixedPointNumbers.Normed{UInt8,8}}) will soon switch to returning 1; you might need to switch to oneunit

Can you tell me what I should change? Thanks!
