Enhanced cross component sample offset filtering system for video coding and decoding

A method, comprising:

• classifying first input samples reconstructed from coded video data representing a first color component of source video orthogonal to a native color component that will be filtered, intensity of the input samples,
• estimating a filter offset based on the classified intensity of the first input samples, and filtering second input samples reconstructed from the coded video data representing the native color component of the source video according to the estimated offset.

A computer readable medium having program instructions stored thereon that, when executed by the processing device, cause the processing device to perform a method, comprising:

• classifying first input samples reconstructed from coded video data representing a first color component of source video orthogonal to a native color component that will be filtered, intensity of the input samples,
• estimating a filter offset based on the classified intensity of the first input samples, and filtering second input samples reconstructed from the coded video data representing the native color component of the source video according to the estimated offset.
