Although there are fillers(滤镀)which can change digital photographs to make them similar to a painting, obvious differences still exist.
A brand-new painting Al has been made public recently. Much like the pupils of the old masters, the new Al studies the work of great painters like Vermeer and Van Gogh and learns to reproduce their works.
The Al, named "paintBot", is the creation of a team of researchers from the University of Maryland, the Bytedance Al Lab and Adobe Research.
PaintBot can not only reproduce the work of different artists but create new works based on photographs in the chosen painter's characteristic style.
To train the Alto imitate(模 仿)a given artist's technique, the researchers would present it with between 3 and 10 reference paintings. With each reference painting it studies, the Al gradually learns to recognize the various characteristics of the given artist's technique, including the stroke(笔画)color, position and size—along with the order in which each brushstroke should be made.
PaintBot uses a technique known as reinforcement learning(强化学习).During the learning process, the Al would practice reproducing reference paintings, which it would then compare with the original work to see how similar the two were and if it was improving its imitation of the artist's style. It takes around six hours for the Al to learn to imitate a given painter.
Once the Al has mastered a particular artist's technique, the researchers could present it with a new image to reproduce in the same style. The Al then uses what it has learnt to produce a new painting, putting down each brushstroke one at a time.
After being trained in a given style, PaintBot takes only around five minutes to produce each of its digital masterpieces.
The way that PaintBot's compositions are built up from thousands of individual brushstrokes makes the AI's works more realistic than those online filters.
