Overview of this book

<p>Android Application Programming with OpenCV 3 is a practical, hands-on guide to computer vision and mobile app development. It shows how to capture, manipulate, and analyze images while building an application that combines photography and augmented reality. To help the reader become a well-rounded developer, the book covers OpenCV (a computer vision library), Android SDK (a mobile app framework), OpenGL ES (a 3D graphics framework), and even JNI (a Java/C++ interoperability layer).</p> <p>Now in its second edition, the book offers thoroughly reviewed code, instructions, and explanations. It is fully updated to support OpenCV 3 and Android 5, as well as earlier versions. Although it focuses on OpenCV's Java bindings, this edition adds an extensive chapter on JNI and C++, so that the reader is well primed to use OpenCV in other environments.</p>

Chapter 3. Applying Image Effects

For this chapter, our goal is to add several image filters to Second Sight. These filters rely on various OpenCV functions to manipulate matrices through splitting, merging, arithmetic operations, or applying lookup tables for complex functions. Certain filters also rely on a mathematics library called Apache Commons Math.
