Abstract: Embodiments are disclosed for a method including obtaining a region of interest of a current frame of a video sequence depicting an object. The method may further include determining, by a mask propagation model, a likelihood of each pixel of the current frame being associated with the object in the region of interest of the current frame based on the region of interest of the current frame and a fixed number of previous frames of the video sequence including the object. The method may further include replacing a previous frame of the fixed number of previous frames with the current frame. The method may further include displaying the current frame of the video sequence including a masked object in the region of interest of the current frame based on the likelihood of one or more pixels of the current frame being associated with the object.

Abstract: Embodiments are disclosed for a machine learning-based chroma keying process. The method may include receiving an input including an image depicting a chroma key scene and a color value corresponding to a background color of the image. The method may further include generating a preprocessed image by concatenating the image and the color value. The method may further include providing the preprocessed image to a trained neural network. The method may further include generating, using the trained neural network, an alpha matte representation of the image based on the preprocessed image.
