Black and white image colorization using Python, OpenCV and Deep Learning

A collection of Deep Learning based Image Colorization papers and corresponding source code/demo program, including Automatic and User Guided (i.e. with User Interaction) colorization, as well as video colorization.

To solve this problem, we propose a two-stage deep colorization method allowing users to control the results by flexibly setting global inputs and local inputs.

We propose a deep learning approach for user-guided image colorization. The system directly maps a grayscale image, along with sparse, local user ``hints" to an output colorization with a Convolutional Neural Network (CNN).

DeepAI Image Colorization 的使用方式很簡單，進到網站之後，點擊 Image 就能上傳你的照片，也支援圖片網址，按 url upload 來切換。

In this paper, a comprehensive review of recent DLIC approaches from algorithm classification to existing challenges is provided to facilitate researchers’ in-depth understanding of DLIC.

Image Colorization API 則是開發公司 DeepAI 用來展示應用的 Web 介面，使用這項工具無須註冊，完全免費，上傳黑白照片即可變成彩色，不過圖片尺寸會降低至 800x800 以下。
