Digital videos are represented as sequences of digital images, while analogue videos are represented as a sequence of continuous time varying signals. Images are taken from a camera or video camera in analogue form and subsequently digitized by certain electronic circuits into digital form.

The Government announced on February 11, 2019 that the Chief Executive in Council has approved to proceed with switching off analogue television services (ASO) on November 30, 2020 (11.59pm). Hong Kong will enter an era of full digital TV broadcasting on December 1, 2020 (00.00 hours).

Linear regression is used when your response variable is continuous. For instance, weight, height, number of hours, etc. Logistic regression is used when the response variable is categorical in nature. For instance, yes/no, true/false, red/green/blue, 1st/2nd/3rd/4th, etc.

Autodesk 3ds Max, formerly 3D Studio and 3D Studio Max, is a professional 3D computer graphics program for making 3D animations, models, games and images. It is developed and produced by Autodesk Media and Entertainment.

A program is said to learn from experience E with respect to task T and performance measure P, if it’s performance at tasks in T, as measured by P, improves with experience E.

首先最重要的就是把握大學四年，大學通常不如高中有那麼重的課業壓力，你會有很多自由的時間。趁大學期間多寫程式、多做不同的專案，尤其畢業專題非常重要。你的忠誠度不能當飯吃，也不要捨不得公司，這世界只有錢才是真的。

Install CUDA is really annoying. So I made this guide to guide myself. Basically we need to first install the correct Driver, then install the CUDA Toolkit and CuDNN.

Azure Kinect DK is a developer kit with advanced AI sensors that provide sophisticated computer vision and speech models. Kinect contains a depth sensor, spatial microphone array with a video camera, and orientation sensor as an all in-one small device with multiple modes, options, and software development kits (SDKs).

2020中的大二期間大概是我人生中最努力的半年。那時候除了學校科目，我也在香港科學園裏做第一次實習。當時我主要是想應付學校的實習要求，所以沒有想清楚就走去報了。學到的東西有用的大概就只有Linux的操作和一些在C++上OOP，Design Pattern的概念。除了工作，我更每天抽時間在Udemy上看網課，當時是看有關OpenCV的Traditional Image Processing網課。那時是我第一次接觸Jupyter Notebook和Google Colab（我以前自學OpenCV的時候都是用IDLE的）。當時大概每天的睡眠時間都很少，幸好中途有一段時間可以Home Office，長達兩小時的午飯時段可以在家偷睡補眠XD。在車上，平時會看社交媒體的我也轉成看非學術類的書/電子書了。

無他，唯手熟爾，就是多讀多寫。論文就是越讀越快的，我還是本科生的時候我導師告訴我剛入門時候要精讀十篇好文章，我現在指導師弟師妹也是給他們挑好幾篇文章讓他們反覆精讀，起初水平不夠的時候看論文很慢，經常抓不住重點都很正常不用急躁。讀多了自然就越來越快了，後期看個摘要，看個插圖甚至看個題目都明白大致內容了。關於coding就是多寫，多去模仿，非計算機科班出身的我剛讀博的時候代碼很差，現在也不算好，但是這幾年在學習別人的代碼後也在慢慢提高，所以現在對於剛進實驗室的師弟師妹我都對他們的代碼有點要求，至少要做到模塊化和覆用性，現在github開源這麽多有很多好的代碼可以去模仿學習，跑跑開源代碼多去寫寫，非常忌憚一個現象就是不動手去寫，總是只跑開源代碼，跑一個換一個框架，沒有開源就什麽也不會了，要動手自己去覆現一些程序。
