Digital cameras are widely used in desktop and notebook PCs. Taking self-portraits is one of the important function of such cameras, which allows users to capture memories, create art, and improve photography techniques. A desktop environment with a large display and a pan-and-tilt camera provides users with a good area for exploring more angles and postures while taking self-portraits. However, most...
In this paper, we present a double hand-gesture interaction (DHGI) method for walk-through in VR environment with an Oculus Rift headset and Leap Motion function. The user can control the avatar (first-person view) to move (walk/run) forward or backward by turning the user's left palm upward or downward, and by turning the avatar to the left or right with the right thumb pointing toward either direction...
This paper proposes an artist-drawing inspired sketch portrait computer-generation technique. We borrow knowledge from artist-drawing procedure in three phases. The first phase is artist-like visual perception, which parses a photo image to structural appearance from global to local. The second phase is artist-like consideration and judgement, which maps previously parsed visual structure and texture...
As one of the important artistic styles of portrait, sketch portrait has wide applications for both digital entertainment and law enforcement. In this paper, an automatic face sketch generation approach is presented by learning from photo-sketch pair examples. Specifically, the relationship between a face photo and its corresponding face sketch is learned on image patch level. By applying this relationship...
