Hi i want to remove the black background from the image attach. I just want to remove the background and give an outline or border to the image remaing and save in transparent png format. How can i make is there any quick way to remove the background. Any suggestion or Help. Thanks
First go into Blender's "Node Editor," and switch it to the compositor editor (using the button with two photographs on it at the bottom of the screen). Check the "Use Nodes" box, and delete the "Render Layer" node. Add an "Image" node, and use it to open your desired image. Drag the image output into the image input of the "Compositor" node, and create a new "Brightness / Contrast" and "Color Ramp" node. Attach the image output of the "Image" node to the image input of the "Bright / Contrast" node, set the contrast to
20 and attach the image output to the fac input of the "Color Ramp" node. Create a new color stop that is completely white, and change its position to .0001. Finally, connect the image output to the alpha input of the "Compositor" node.
Back in the "3D View" tab, delete everything in the scene by pressing A and then X. In the "Render" panel, set the resolution to that of your desired image, and set the samples down to 0. Give that baby a render, and everything should look correct. Select "Image > Save As Image" to save the final result. It should look like this:
This is sort of an inconvenient, and imprecise, way to delete an image's background, however. Blender isn't really designed for this kinda thing. I recommend going into Adobe Photoshop instead, and using the "Magnetic Lasso" tool or something to mask out the image. This also only works for removing the black parts of an image, so it's not very specific or user friendly. Good luck, though, and let me know if you have any questions. Happy Blendering!
