The entire (simplified) process can be summarized as: Given the input L channel and the predicted ab channels we can then form our final output image. Since the L channel encodes only the intensity, we can use the L channel as our grayscale input to the network.įrom there the network must learn to predict the a and b channels.

The L channel encodes lightness intensity onlyĪ full review of the Lab color space is outside the scope of this post (see this guide for more information on Lab), but the gist here is that Lab does a better job representing how humans see color.

But unlike the RGB color space, Lab encodes color information differently: Similar to the RGB color space, the Lab color space has three channels. started with the ImageNet dataset and converted all images from the RGB color space to the Lab color space. decided to attack the problem of image colorization by using Convolutional Neural Networks to “hallucinate” what an input grayscale image would look like when colorized.

Previous approaches to black and white image colorization relied on manual human annotation and often produced desaturated results that were not “believable” as true colorizations. The technique we’ll be covering here today is from Zhang et al.’s 2016 ECCV paper, Colorful Image Colorization. How can we colorize black and white images with deep learning? Figure 1: Zhang et al.’s architecture for colorization of black and white images with deep learning. We’ll then explore some examples and demos of our work.

In the first part of this tutorial, we’ll discuss how deep learning can be utilized to colorize black and white images.įrom there we’ll utilize OpenCV to colorize black and white images for both:

Scanning your photo will only take a few minutes so you can take your original home while we work on the digital photo restoration.Looking for the source code to this post? Jump Right To The Downloads Section Black and white image colorization with OpenCV and Deep Learning If you are in the area (or do not mind a drive) feel free to stop into our New Jersey office between 9:00-5:00 (Monday thru Friday) and we will be happy to scan your image and discuss what you like done. When your digital photo restoration is complete, we will ship back your original in the same condition it was received. We will contact you as soon as your original is received at our secure facility in New Jersey.

Just place your order and we will provide you with a shipping label and tracking number. If you do not have access to a photo scanner or have slides or negatives in need of restoration, we are happy to scan your items for you. Be sure to scan your photo at a minimum resolution of 300 DPI (ideally 600 DPI or higher). If you do not have a scanner, you can bring your photo to the nearest Officemax, Staples, Office Depot, or FedEx Office and have them scan it for you. If you have a scanner at home you can scan your photo and upload it above, or email it to us. If you are not satisfied with your newly restored photos, we will revise them until you are. Once complete, we will email you a proof for your review. Severely damaged photos can take several hours to repair, as this is not an automated process.

With your approval, our photo colorization technicians will get to work!Įach photo is meticulously colorized individually using specialized software and advanced techniques. Assessments are free of charge and there is no obligation until you accept and remit a deposit. Once we have your digital photo and learn exactly what result you are looking for, we will let you know if a basic, moderate or severe restoration is required to make it picture perfect. To ensure the safety of your original photos, we carefully flatbed scan each picture by hand at minimum resolution of 600 DPI. You can upload or email the digital photo to us or have us scan it for you. The process of adding color to black and white photos begins with scanning a high-resolution image of your photograph.
