Embodiment Construction
[0024] In order to reduce the complexity of inter-frame prediction mode selection and improve processing efficiency, embodiments of the present invention provide a HEVC inter-frame prediction mode selection method and device.
[0025] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0026] The core idea of the inter-frame mode selection provided by the embodiment of the present invention is: by comparing the first rate-distortion cost calculated based on the Sum of Absolute Difference (SAD) of various inter-frame prediction modes, and calculating the optimal and secondary The ratio of the difference between the optimal first rate-distortion cost and the optimal first rate-distortion cost, by setting a threshold, if the ratio satisfies the threshold condition, the optimal inter-frame prediction mode is obtained directly through the first rate-distortion cost, Otherwise, perform the second SSE-bas...
