Adobe just revealed a powerful new tool that's coming soon to Photoshop CC. Called "Select Subject," it uses machine learning to detect subjects in your photos to help you isolate them from the backgrounds.
Adobe's amazing Image Deblurring demo was the star of the Sneak Peeks event at Adobe MAX 2011, but it was just one of the many demos shown that night. Another interesting photography-related demo was for "Pixel Nuggets": a feature that lets you search a large library of photos for features (e.g. people, landmarks, patterns, logos).
