1. 导读 本报告的主要内容是阅读《Colorization Using Optimization》论文之后对原理进行理解并利用python复现论文中的照片上色算法。 2. 引言 在论文发布前现有的技术中,图片上色是一个耗费大量人力、花费较多时间的任务。且“将图像划分为多个区域”常采用自动分割算法,
机器学习:Colorization using Optimization 今天介绍 Siggraph 2004 年的一篇文章: Colorization using Optimization,利用优化的方法对灰度图像进行着色,这里用到了非常经典的泊松方程以及稀疏矩阵的线性优化。简单来说,就是对一张灰度图像先人为地进行着色,然后利用优化的方法,对其他的没有颜色的区域进行填充。这些处理都是...
4. Results and comparisons We train our method using the Visible Human 2 [1] 16- bit MRI and color cryo dataset. Our code is written in Python where we use PyTorch [23] for training the GAN and PyAMG [22] for solving the optimization problem to generate the colorized volume. Our ...

Colorize Black & White Astronomical Images Using Python, PyTorch, and FastAPI What you’ll learn Discover the fundamentals of Generative Adversarial Networks (GANs) and understand their architecture, loss functions, and optimization challenges.
Many colorization papers have been published using traditional computer vision methods. One of my favorites is a paper titled Colorization using Optimization by Anat Levin, Dani Lischinski, and Yair Weiss. It used a few colored scribbles to guide an optimization problem for solving colorization. ...
