Back in February and shortly before MWC, developer Scalado unveiled an app called Remove. Put simply, the app allowed you to remove unwanted objects from images - for example, if your significant other is posing in front of the Louvre, you can remove other tourists from the picture. It works by taking multiple photos of the scene, then determining which ones moved through, and removing them at a touch.
As you can see in the video above, Remove was demoed on an Android device, suggesting with relative certainty that an Android app was near. Unfortunately, Nokia has acquired the company (you know, with all that spare cash they have), meaning it's unlikely Remove for Android will ever see the light of day.
