Abstract
Systems and methods for frame and scene segmentation are disclosed herein. A disclosed method includes providing a frame of a scene. The scene includes a scene background. The method also includes providing a model of the scene background. The method also includes determining a frame background using the model and subtracting the frame background from the frame to obtain an approximate segmentation. The method also includes training a segmentation network using the approximate segmentation.
Claims16
A computer-implemented method comprising:
- providing a frame of a scene, the scene including a scene background, the scene background being a chroma screen;
- providing a model of the scene background based on fitting an intensity plane to the chroma screen in the frame;
- determining a frame background using the model based on mixing a chroma of the chroma screen with the intensity plane;
- subtracting the frame background from the frame to obtain an approximate segmentation;
- and
- training a segmentation network using the approximate segmentation.
A non-transitory computer-readable medium storing instructions to execute a computer-implemented method, the method comprising:
- providing a frame of a scene, the scene including a scene background, the scene background being a chroma screen;
- providing a model of the scene background based on fitting an intensity plane to the chroma screen in the frame;
- determining a frame background from the model based on mixing a chroma of the chroma screen with the intensity plane;
- subtracting the frame background from the frame to obtain a frame foreground;
- and
- training a segmentation network using the frame foreground.
