In this chapter, we will cover basic image and audio (WAV files) processing with NumPy and SciPy. We will use NumPy to do interesting things with sounds and images:
- Loading images into memory maps
- Combining images
- Blurring images
- Repeating audio fragments
- Generating sounds
- Designing an audio filter
- Edge detection with the Sobel filter
This should be a fun chapter. Although all the chapters in this book are fun, in this chapter we are going to really go for it and concentrate on having fun. In Chapter 10, Fun with Scikits, you will find a few more image processing recipes that use scikits-image.
Unfortunately, this book does not have a direct support for audio files, so you will really need to run the code examples to appreciate the recipes fully. The source code should be available from the book website http://www.packtpub.com/.
