Video quality assessing method and apparatus

A video quality assessing apparatus comprising:

• a memory storing one or more instructions;
• and
• a processor configured to execute the one or more instructions stored in the memory to:
• obtain a model-based quality score for each of a plurality of sub-areas included in a frame by using a neural network, the neural network being trained based on a mean opinion score (MOS) obtained by using an assessor display apparatus,
• obtain a weight matrix from at least one of rendering information or screen information about a screen included in a user display apparatus,
• apply the weight matrix to the model-based quality score obtained for each sub-area, and
• obtain a quality score of the frame, based on the model-based quality score obtained for each sub-area to which the weight matrix is applied.

A non-transitory computer-readable recording medium having recorded thereon a program that is executed by a computer to perform a video quality assessing method, the video quality assessing method comprising:

• obtaining a model-based quality score for each of a plurality of sub-areas included in a frame by using a neural network, the neural network being trained based on a mean opinion score (MOS) obtained by using an assessor display apparatus;
• obtaining a weight matrix from at least one of rendering information or screen information about a screen included in a user display apparatus;
• applying the weight matrix to the model-based quality score for each sub-area of the plurality of sub-areas;
• and
• obtaining a quality score of the frame, based on the model-based quality score for each sub-area to which the weight matrix is applied.
