A video is just a series of image frames shown in succession. Thus, processing a video is just processing all the image frames one by one. In this activity, we use image processing of the image frames to get the acceleration of a tennis ball rolling over a slide.
Dark images are not at all dark. In fact, the details are captured by the camera but our eyes just do not see it. In this activity we show how we can manipulate the histogram of an image so that our eyes can see the details in the dark.
