Presentations Day #1

Winter 2021

不久之前，RD的夥伴們完成了一場精彩絕倫的分享！ 這次有四位同仁分享覺得有趣的主題，分別為：

• Lego CI/CD with github action
• The wet codebase
• Enlarge eyes by Apple face detection and Metal shader
• Smooth skin principle and implementation

快來看看這次的Presentations吧！

Enlarge eyes by Apple face detection and Metal shader

• Introduce Metal and compare to OpenGL ES
• Introduce Vision
• Enlarge eyes algorithm

Smooth skin principle and implementation

本篇介紹 GPUImage 中一個常用的美肌濾鏡，並深入解釋其中使用高斯模糊濾鏡的原因及原理。

• Overview of filter pipeline
• Box blur vs. Gaussian blur and how to implement with shader
• Why Gaussian blur is suitable for smooth skin (fourier transform, low-pass filter)
• Filter pipeline principle summary
• Direction to improve performance and combine with face detection

Lego CI/CD with Github Actions

Using features on Github (Github Action, Github App, Github Deployment) implement a GitOps flow which make application developer and DevOps engineer cowork with each other easier, and how this flow improve the development experience.
