By adding an equal amount of red and blue, it makes the green brighter. To achieve the color white, for example, you need an equal distribution of all colors. The layers not only determine color, but also brightness. Intuitively, you might think that the plant is only present in the green layer.īut, as you see below, the leaf is present in all three channels. Imagine splitting a green leaf on a white background into the three channels. The values span from 0 - 255, from black to white.Ĭolor images consist of three layers: a red layer, a green layer, and a blue layer.
Each pixel has a value that corresponds to its brightness.

In this section, I’ll outline how to render an image, the basics of digital colors, and the main logic for our neural network.īlack and white images can be represented in grids of pixels.

You can also check out the three versions on FloydHub and GitHub, along with code for all the experiments I ran on FloydHub’s cloud GPUs. If you want to look ahead, here’s a Jupyter Notebook with the Alpha version of our bot. To make the coloring pop, we’ll train our neural network on portraits from Unsplash. We’ll use an Inception Resnet V2 that has been trained on 1.2 million images.
We’ll be able to color images the bot has not seen before.įor our “final” version, we’ll combine our neural network with a classifier. The next step is to create a neural network that can generalize - our “Beta” version. There’s not a lot of magic in this code snippet - which is helpful so that we can get familiar with the syntax. We’ll build a bare-bones 40-line neural network as an “Alpha" colorization bot. The first section breaks down the core logic. I’ll show you how to build your own colorization neural net in three steps. Yet, if you’re new to deep learning terminology, you can read my previous two posts and watch Andrej Karpathy’s lecture for more background. A face alone needs up to 20 layers of pink, green and blue shades to get it just right. In short, a picture can take up to one month to colorize. To appreciate all the hard work behind this process, take a peek at this gorgeous colorization memory lane video. Today, colorization is done by hand in Photoshop. First off, let’s look at some of the results/failures from my experiments (scroll to the bottom for the final result). I was fascinated by Amir’s neural network, so I reproduced it and documented the process.

They were astonished with Amir’s deep learning bot - what could take up to a month of manual labour could now be done in just a few seconds.
