Method performed by electronic apparatus, electronic apparatus and storage medium for video processing based on feature map

An electronic apparatus comprising:

• at least one processor;
• and
• a memory storing computer executable instructions,
• wherein the computer executable instructions, when being executed by the at least one processor, cause the electronic apparatus to:
• determine a local frame sequence from a video;
• obtain a feature map sequence of the local frame sequence by encoding the local frame sequence;
• determine 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;
• obtain 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
• obtain 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.
