Overview of this book

Multimedia applications are used by a range of industries to enhance the visual appeal of a product. This book will teach the reader how to perform multimedia processing using Python. This step-by-step guide gives you hands-on experience for developing exciting multimedia applications using Python. This book will help you to build applications for processing images, creating 2D animations and processing audio and video. Writing applications that work with images, videos, and other sensory effects is great. Not every application gets to make full use of audio/visual effects, but a certain amount of multimedia makes any application a lot more appealing. There are numerous multimedia libraries for which Python bindings are available. These libraries enable working with different kinds of media, such as images, audio, video, games, and so on. This book introduces the reader to the most widely used open source libraries through several exciting, real world projects. Popular multimedia frameworks and libraries such as GStreamer,Pyglet, QT Phonon, and Python Imaging library are used to develop various multimedia applications.

Preface

Chapter 3. Enhancing Images

In the previous chapter, we learned a lot about day-to-day image processing. We accomplished the learning objective of performing basic image manipulation by working on several examples and small projects. In this chapter, we will move a step further by learning how to add special effects to an image. The special effects added to the image serve several purposes. These not only give a pleasing appearance to the image but may also help you to understand important information presented by the image.

In this chapter, we shall:

  • Learn how to adjust brightness and contrast levels of an image

  • Add code to selectively modify the color of an image and create gray scale images and negatives

  • Use PIL functionality to combine two images together and add transparency effects to the image

  • Apply various image-enhancement filters to an image to achieve effects such as smoothing, sharpening, embossing, and so on

  • Undertake a project to develop a tool to add a watermark or text or a date...
