Samsung patents video editing method to remove objects from moving footage
Samsung describes a method for electronic devices to remove specific objects from video clips. The system breaks the video into frames, creates a digital map of visual features, and uses a mask to identify the object to be deleted. It then blends information from neighboring frames to fill in the gaps left by the removed object.
In the filing’s own words
A method performed by an electronic apparatus, includes: determining a local frame sequence from a video; obtaining a feature map sequence of the local frame sequence by encoding the local frame sequence; determining a feature flow sequence of the local frame sequence based on the feature map sequence of the local frame sequence and a mask image sequence regarding an object to be removed, the mask image sequence being corresponding to the feature map sequence; obtaining an updated feature map sequence of the local frame sequence, by performing, based on the feature flow sequence, feature fusion between adjacent feature maps in the feature map sequence; and obtaining a processed local frame sequence, by decoding the updated feature map sequence of the local frame sequence.
What exactly they claim (claim 1)
1. A method performed by an electronic apparatus, comprising: determining a local frame sequence from a video; obtaining a feature map sequence of the local frame sequence by encoding the local frame sequence; determining a feature flow sequence of the local frame sequence based on the feature map sequence of the local frame sequence and a mask image sequence regarding an object to be removed, the mask image sequence being corresponding to the feature map sequence; obtaining an updated feature map sequence of the local frame sequence, by performing, based on the feature flow sequence, feature fusion between adjacent feature maps in the feature map sequence; and obtaining a processed local frame sequence, by decoding the updated feature map sequence of the local frame sequence, wherein the determining the feature flow sequence of the local frame sequence based on the feature map sequence of the local frame sequence and the mask image sequence regarding the object to be removed comprises: determining an occlusion mask image sequence and the feature flow sequence of the local frame sequence based on the feature map sequence of the local frame sequence and the mask image sequence regarding the object to be removed, and wherein the obtaining the updated feature map sequence of the local frame sequence comprises: performing the feature fusion between adjacent feature maps in the feature map sequence based on the occlusion mask image sequence, the feature flow sequence, and the mask image sequence regarding the object to be removed.
