本书目的：

目前，4方面趋势使得图像处理成为一个发展迅速的领域

1 人手一手机；

2 互联网和搜索引擎聚合图像视频大数据；

3 计算更加廉价；

4 图像算法更成熟。

【作者没有在这里提及工业 军事等经典运用，而是强调移动互联 大数据 以及深度学习等方面是图像处理未来发展的趋势，观点鲜明】

本书目的：

1 OpenCV函数文档；

2 给读者对于图像处理过程的直观认识；

3 让读者知晓什么时候该用什么方面的算法，还有如何使用这些算法；

4 提供图像处理和机器学习方面的代码，能够立刻入门和提高；

5 ……

【多次将“ 图像处理和机器学习”放在同一个等级上面，证明作者认为，已经不能仅仅考虑图像处理问题，必须和训练练习在一起考虑 】

书本对象：

专家和企业雇员 对于这些在实际工作中需要专业的/能够快速开发的图像处理系统人员来说，sample code是一个很好的开始。我们的简介能够让读者迅速知道算法和模型如何使用。……

In the first edition (Learning OpenCV) I singled out some of the great teachers who

helped me reach the point where a work like this would be possible. In the interven‐

ing years, the value of the guidance received from each of them has only grown more

clear. My many thanks go out to each of them. I would like to add to this list of extra‐

ordinary mentors Tom Tombrello, to whom I owe a great debt, and in whose mem‐

ory  I  would  like  to  dedicate  my  contribution  to  this  book.  He  was  a  man  of

exceptional intelligence and deep wisdom, and I am honored to have been given the

opportunity to follow in his footsteps. Finally, deep thanks are due the OpenCV com‐

munity,  for  welcoming  the  first  edition  of  this  book  and  for  your  patience  through

the many exciting, but perhaps distracting, endeavors that have transpired while this

edition was being written.

This  edition  of  the  book  has  been  a  long  time  coming.  During  those  intervening

years,  I  have  had  the  fortune  to  work  with  dozens  of  different  companies  advising,

consulting,  and  helping  them  build  their  technology.  As  a  board  member,  advisory

board  member,  technical  fellow,  consultant,  technical  contributor,  and  founder,  I

have had the fortune to see and love every dimension of the technology development

process. Many of those years were spent with Applied Minds, Inc., building and run‐

ning  our  robotics  division  there,  or  at  Applied  Invention  corporation,  a  spinout  of

Applied  Minds,  as  a  Fellow  there.  I  was  constantly  pleased  to  find  OpenCV  at  the

heart of outstanding projects along the way, ranging from health care and agriculture

to aviation, defense, and national security. I have been equally pleased to find the first

edition of this book on people’s desks in almost every institution along the way. The

technology  that  Gary  and  I  used  to  build  Stanley  has  become  integral  to  countless

projects since, not the least of which are the many self-driving car projects now under

way—any one of which, or perhaps all of which, stand ready to change and improve

daily life for countless people. What a joy it is to be part of all of this! The number of

incredible  minds  that  I  have  encountered  over  the  years—who  have  told  me  what

benefit the first edition was to them in the classes they took, the classes they taught,

the careers they built, and the great accomplishments that they completed—has been

a continuous source of happiness and wonder. I am hopeful that this new edition of

the book will continue to serve you all, as well as to inspire and enable a new genera‐

tion of scientists, engineers, and inventors.

As the last chapter of this book closes, we start new chapters in our lives working in

robotics, AI, vision, and beyond. Personally, I am deeply grateful for all of the people

who  have  contributed  the  many  works  that  have  enabled  this  next  step  in  my  own

life: teachers, mentors, and writers of books. I hope that this new edition of our book

will enable others to make the next important step in their own lives, and I hope to

see you there!

I founded OpenCV in 1999 with the goal to accelerate computer vision and artificial

intelligence and give everyone the infrastructure to work with that I saw at only the

top labs at the time. So few goals actually work out as intended in life, and I’m thank‐

ful this goal did work out 17 (!) years later. Much of the credit for accomplishing that

goal was due to the help, over the years, of many friends and contributors too numer‐

ous  to  mention.2  But  I  will  single  out  the  original  Russian  group  I  started  working

with  at  Intel,  who  ran  a  successful  computer  vision  company  (Itseez.com)  that  was

eventually bought back into Intel; we started out as coworkers but have since become

deep friends.

With three teenagers at home, my wife, Sonya Bradski, put in more work to enable

this book than I did. Many thanks and love to her. The teenagers I love, but I can’t

say they accelerated the book. :)

This  version  of  the  book  was  started  back  at  the  former  startup  I  helped  found,

Industrial Perception Inc., which sold to Google in 2013. Work continued in fits and

starts on random weekends and late nights ever since. Somehow it’s now 2016—time

flies when you are overwhelmed! Some of the speculation that I do toward the end of

Chapter  23  was  inspired  by  the  nature  of  robot  minds  that  I  experienced  with  the

PR2, a two-armed robot built by Willow Garage, and with the Stanley project at Stan‐

ford—the robot that won the $2 million DARPA Grand Challenge.

As  we  close  the  writing  of  this  book,  we  hope  to  see  you  in  startups,  research  labs,

academic sites, conferences, workshops, VC offices, and cool company projects down

the  road.  Feel  free  to  say  hello  and  chat  about  cool  new  stuff  that  you’re  doing.  I

started OpenCV to support and accelerate computer vision and AI for the common

good; what’s left is your part. We live in a creative universe where someone can create

a pot, the next person turns that pot into a drum, and so on. Create! Use OpenCV to

create something uncommonly good for us all!
