Overview of this book

<p>Most technologies are developed with an inspiration of human capabilities. Most of the time, the hardest to implement capability is vision. Development of highly capable computer vision applications in an easy way requires a generic approach. In this approach, Arduino is a perfect tool for interaction with the real world. Moreover, the combination of OpenCV and Arduino boosts the level and quality of practical computer vision applications.</p> <p>Computer vision is the next level of sensing the environment. The purpose of this book is to teach you how to develop Arduino-supported computer vision systems that can interact with real life by seeing it.</p> <p>This book will combine the powers of Arduino and computer vision in a generalized, well-defined, and applicable way. The practices and approaches in the book can be used for any related problems and on any platforms. At the end of the book, you should be able to solve any types of real life vision problems with all its components by using the presented approach. Each component will extend your vision with the best practices on the topic.</p> <p>In each chapter, you will find interesting real life practical application examples about the topics in the chapter. To make it grounded, we will build a vision-enabled robot step by step towards the end of the book. You will observe that, even though the contexts of the problems are very different, the approaches to solve them are the same and very easy!</p> <p>&nbsp;</p>

Extracting features


Vision data itself is a multidimensional pixel array and, when we see this type of data, our brain intuitively extracts information from it. Actually, extracting such high level information from a dataset is a very complex operation. This operation should take a huge amount of zeros and ones as the input data and it should convert this data into a conclusion such as, "Yes, this is a car!", or sometimes even, "This is Randy's car!". Maybe this process sounds very easy for you but, for computers, it is not.

A computer and the human brain work very differently. As a result, a computer is much more powerful when making calculations and the brain is much more capable with high level tasks such as scene interpretation. So, this chapter concentrates on a weak element of computer science. Despite this, it is surely possible to interpret vision scenes intelligently by using computers, but the approach of extracting meaningful information from vision data is an indirect way of approaching...
