Image filtering is the process of changing or extracting one aspect of the digital image representation to make the image look different. For instance, a red-channel filter uses only the red channel of an image, clearing the blue and green channel. In contrast, a green-channel filter uses only the green channel of an image, clearing the red and blue channels. The effect of these two filters is shown in Figure 1. FIGURE 1. ORIGINAL IMAGE. GREEN AND RED CHANNEL FILTERS. In this Milestone, your team will write four of the simplest image filters, to be called respectively: red_channel green_channel blue_channel combine Each filter has an image file as a parameter and returns an altered version of that image file (see Figure 2). The red/green/blue channel filters return an image that contains only the red/green/blue portions of the input image (e.g. p2_original.png). The combine filter (shown on the right-hand side of Figure 2) reverses this process. The combine() filter accepts three image files (red/blue/green_channel.png), and returns a single image file that is a combination of those three files. If you have coded everything correctly, 5
