An interactive algorithm for soft segmentation and matting of natural images and videos is presented in this paper. The technique follows and extends [11], where the user first roughly scribbles/labels different regions of interest, and from them the whole data is automatically segmented. The segmentation and alpha matte are obtained from the fast, linear complexity, computation of weighted dis...

Image Composition, which is a process of combining two or more images, plays an important role in film production. It has been a central part of image processing. Digital Matting is necessary to make a complicated composition since it enables to extract only a foreground object from an arbitrary image and replace its background with another image. Recently a number of digital matting algorithms...

One of the most common tasks in image and video editing is the local adjustment of various properties (e.g., saturation or brightness) of regions within an image or video. Edge-aware interpolation of user-drawn scribbles offers a less effort-intensive approach to this problem than traditional region selection and matting. However, the technique suffers a number of limitations, such as reduced p...

We propose a novel neural-network-based method to perform matting of videos depicting people that does not require additional user input such as trimaps. Our architecture achieves temporal stability the resulting alpha mattes by using motion-estimation-based smoothing image-segmentation algorithm outputs, combined with convolutional-LSTM modules on U-Net skip connections. also fake-motion gener...

Recently, alpha matting has received a lot of attention because its usefulness in mobile applications such as selfies. Therefore, there been demand for lightweight model due to the limited computational resources commercial portable devices. To this end, we suggest distillation-based channel pruning method networks. In step, remove channels student network having fewer impacts on mimicking know...

Extracting accurate foregrounds from natural images benefits many downstream applications such as film production and augmented reality. However, the furry characteristics various appearance of foregrounds, e.g., animal portrait, challenge existing matting methods, which usually require extra user inputs trimap or scribbles. To resolve these problems, we study distinct roles semantics details f...
