In today's modern science and technology areas, images and videos have gained broader scope due to the ever-growing importance of scientific visualization and digitization. In this chapter, you will get introduced to the basics of image processing. Once you have understood the basics of image processing, the image processing library, which needs to be installed on Raspberry Pi, will get introduced. Later in this chapter, we will perform basic image processing operation on Raspberry Pi followed by interesting projects creating a time-lapse video and Twitter-controlled Raspberry Pi camera. The following topics are covered in this chapter:
