Android Application Programming with OpenCV

This book is tiny. It's incredibly small. It's width is about half that of the diameter of a United States dime. So it's a little under a centimeter thick. That's the first thing I noticed when the book finally arrived. When I previewed the book here on Amazon I thought it clipped the chapter titles. There really are only five chapters. It's an incredibly short programming book compared to others at just 112 pages. The first 30 pages are setting up OpenCv to work with eclipse. So content wise it doesn't even get into programming anything until one is almost a third or a little over a fourth of the way through the book.I feel a little ripped off to be honest. I don't think the book is worth the cost. However it's the only book on the market which covers this topic. What little content there is I guess gets covered well enough. However there's not much. One might be better off doing the tutorials on the OpenCV website and then finding supplementary material online. I think the publishers rushed this one out to market figuring there was a market for it. I wish the author and the publishers would have done more than meet the bare minimum of expectations though.I was really excited to receive this book. It's such an interesting topic. Perhaps I'm a little biased as I did have such high expectations. It's worth reading through to learn some of the material I just don't think it's worth the full price of the book because it's rather skimpy on material. What material there is however is covered well enough as I mentioned.

I was very interested in learning about object recognition using opencv/android/java. There was a good example of using one of the feature detection types, but I was a little disappointed that it didn't go into more depth on the topic, or cover other techniques OpenCV supports like haar cascades, template matching, color thresholds(BGR vs HSV), contours with polygons, etc., and the different feature detecting methods( surf, sift, etc). Maybe the author is setting up a sequel.There is lots of OpenCV example code available in C++ that you can find google, but good Java/Android examples are hard to come by. This book provides a few good examples of working with the camera and doing some OpenCV stuff. Too short but what is there is good stuff. It leaves the audience wanting more.

Just started this book...only a couple chapters in. This makes a great book after a couple introductoy books on Java for Android development. I love the direct approach of pushing the compiled code to the phone rather than running it on a virtual device. I will definitely be studying this book...it is what I needed.

Short and sweet! Great way to get your feet wet in Computer Vision and Graphics on Android.

This book guides for easy start of OpenCV at Android environment. It starts with the scratch and basics such as development environment setting through practical examples, so it helps to even novice of both Android and OpenCV. Since this book is not thick and easily read, we can go through the book quickly and can go to the next level.

If you’re planning on doing some OpenCV Android development buy this book! It will undoubtedly pay for itself in time savings.The book has lots of detail and screenshots to guide you through making your own app which is helpful for working with more graphical type things like Eclipse. I think this book would save a developer looking to get started with Android and OpenCV a lot of time and remember people time is money (money you could spend on this book).

I received a review copy from PacktPub.comThe book does a nice job of introducing the reader to OpenCV under Android. It starts with the basics (installing, setting up the development environment, and compiling), then moves on to capturing images, applying filters/effects, tracking in 2D, tracking in 3D, and finally rendering 3D objects on top of a camera image for Augmented Reality.The code in the book is provided for easy compiling, and is nicely commented for easy reading.

GREAT book for new to android programmers. It's light, easy to follow, and provides a good overview of various image processing features. Sample projects are fun and easy to develop or modify for your own use.

Nice and compact book - gets started on OpenCV and Image processing with Android! However, could have been little more elaborate on OpenCV fundamentals too.
