Content-aware

Content-awareness is a useful aspect of Photoshop where image editing is done automatically and intelligently. It comes in two forms, content-aware scaling, and content-aware filling, in which elements in a background automatically recompose according to the areas a user of the program decides to fill or scale. More specifically, content-aware scaling works by rescaling an image and causing its content to adapt to the new dimensions and preserving important areas of it. Content-aware filling functions by matching tone, color, and noise of an area of the image that contained an object or detail in which the user decides to remove.[
