Now a days there are so many way to manipulate an image to suit your needs, like removing wrinkles, remove acne, look slimmer. But one of the basic requirements I think is to remove background in images and to remove unwanted objects from photos.
Previously one had to use photoshop to carefully edit photo to remove objects in images but after photoshop’s content aware fill the process became a one step deal. But here is a free online alternative.
Webinpaint (Link) is a online app similar to Photoshops Content Aware Fill feature. WebInpaint allow you to remove unwanted element from your photo quickly and easily without Adobe Photoshop.
Upload your photo, then paint over the area to be removed and click Inpaint button. No registration required. For simple photographs without much texture or clutter, the app actually works quite well.Zoom in and zoom out options available.
PhotoWipe (Link) is a revolutionary image processing tool that magically removes unwanted objects from your photos. Just paint over them in black, and click go! Uncovers hidden details in your photos. Sit back and watch as cage bars disappear from the zoo, and your old girlfriend or boyfriend fades away. It removes wrinkles, blemishes, acne, or it can remove entire facial features. You can use it like a photoshop content aware fill alternative.
Step 1 : First, open the original image. To make it easy, you can drag an image from any folder and drop it into the PhotoWipe application.
Step 2 : Next, paint the parts that you don’t want black. PhotoWipe works best when covering small, or long and thin portions of the photo. Otherwise, it is harder to guess what should be there.
Step 3 : After you have done blacking out parts of the photo, you can preview the result. PhotoWipe can take several minutes to do its work, and you will be able to see what is going on the whole time. Presto, now you can save the finished product, or copy it to the clipboard.
But for best results, use photoshop. Here is a simple video tutorial (link) to remove unwanted objects in photos using photoshop.
