Method and electronic device for compressing a video using ai-based in loop filter

A method for managing multi pre-processors for an AI-based In Loop Filter (AILF) in a video codec, comprising:

• obtaining, by an electronic device, an encoded video and an index corresponding to at least one selected pre-processor;
• determining, by the electronic device, the at least one selected pre-processor for decoding the encoded video based on the index corresponding to the at least one selected pre-processor;
• and
• decoding, by the electronic device, the encoded video using a set of ratios of the at least one selected pre-processor.

An electronic device for managing multi pre-processors for an AI-based In Loop Filter (AILF) in a video codec, comprising:

• memory configured to store one or more instructions;
• and
• at least one processor comprising the multi pre-processors, wherein the at least one processor is configured to execute the one or more instructions to cause the electronic device to:
• obtain a video comprising a plurality of frames, wherein each frame of the plurality of frames comprises a plurality of channels, wherein each channel of the plurality of channels comprises image information;
• extract at least one feature from each frame of the plurality of frames;
• select at least one pre-processor from the multi pre-processors for applying the AILF based on the at least one extracted feature, wherein each pre-processor of the multi pre-processors comprises a set of ratios,
• wherein each ratio of each set of ratios corresponds to the plurality of channels;
• generate an encoded video by encoding the image information from each channel of the plurality of channels using the at least one selected pre-processor;
• and
• transmit the encoded video and an index corresponding to the at least one selected pre-processor to a decoder.
