Abstract
An image processing method includes obtaining statistics information of a block of an image frame, determining whether the statistics information satisfies a condition, and disabling cross-component filtering (CCF) for the block in response to the statistics information satisfying the condition.
Claims17
An image processing method, applied to an encoder, and the method comprising:
- obtaining, by the encoder, statistics information of a block of an image frame;
- determining, by the encoder, whether the statistics information satisfies a condition;
- in response to determining the statistics information satisfies the condition, determining, by the encoder, CCF (cross component filtering) signaling be disabled;
- and
- excluding, by the encoder, the CCF signaling in a bitstream transmitted to a decoder, the bitstream corresponding to the block, comprising:
- excluding a CCF flag in the bitstream transmitted to the decoder.

An image processing apparatus, comprising:
- an encoder, the encoder including:
- a memory storing computer program instructions;
- and a processor coupled to the memory and configured to execute the computer program instructions and perform:
- obtaining, by the encoder, statistics information of a block of an image frame;
- determining, by the encoder, whether the statistics information satisfies a condition;
- in response to determining the statistics information satisfies the condition, determining, by the encoder, CCF (cross component filtering) signaling be disabled;
- and
- excluding, by the encoder, the CCF signaling in a bitstream transmitted to a decoder, the bitstream corresponding to the block, comprising:
- excluding a CCF flag in the bitstream transmitted to the decoder.
