That project takes a folder and process all files, I just need an image so I did this: private Bitmap RemoveBackground(Bitmap input)īitmap clone = new Bitmap(input.Width, input.Height, PixelFormat.Format32bppArgb) I looked for a different solution and I found a project that uses a more efficient method here. I've tried Mario solution and it worked perfectly but it's a bit slow for me. You can also add smoothening between frames, blending (where there's less green difference), etc. Just note that you might need different thresholds ( 8 and 96 in my code above), you might even want to use a different term to determine whether some pixel should be replaced. I've used an example image from Wikipedia and got the following result: Iterate over all piels from top to bottom.įor (int y = 0 y 96 // minimum difference between smallest/biggest value (avoid grays)
Bitmap input = new output = new Bitmap(input.Width, input.Height) Just note that this isn't necessarily the most performant way to do this.

While I used Windows Forms, it should be portable without problems and I'm pretty sure you'll be able to interpret the code. I've toyed around a bit using some simple sample code. While this would work with very basic scenes, it can screw you up (e.g. The most basic formula would involve something as simple as "determine whether green is the biggest value". The basics are simple: Compare the image pixel's color with some reference value or apply some other formula to determine whether it should be transparent/replaced.
Since at least some links on your linked page are dead, I tried my own approach: Step 4: Adjust the Brush Size, Hardness, and Strength, then paint around your subject to remove the background.It will work, even if the background isn't uniform, you'll just need the proper strategy that is generous enough to grab all of your greenscreen without replacing anything else. (There's a few ways to do this method, the following steps are what we've found to be the easiest.) Click Invert Selection to reveal your image.

Pro Tip: Use our Cutout tool for a more versatile selection of background removal tools. Read more about the Isolate Subject tool. If your image has multiple subjects or a very busy background, you may need to manually remove the background. This tool works really well for images with defined subjects. Step 2: Click Isolate Subject to let our A.I. Step 1: Follow Step 1 & 2 above, then select Erase mode. Pro Tip: If you have the Opacity at 100 and adjust the Fill Amount, you'll get a nice color overlay on your image. Step 6: Adjust the Fill Amount and Opacity sliders to see your image come through the color overlay. Step 5: Click the color swatch for Fill Color, then select your color using the Color Picker. Step 4: To enable the color options, uncheck Transparent. For a solid colored background, continue to Step 4. If a transparent background image is what you want, you can click Apply now. Step 3: By default, when you select the Background tool your image will become transparent (that checkerboard signifies transparency). Step 2: Select the Background tool in the Edit section of the left-hand menu. Step 1: Open your image in the Photo Editor
