Patent ID: 10425643

Abstract:
A method and system for view optimization of a 360 degrees video is provided. The method includes generating two-dimensional video frame from the 360 degrees video. The macroblocks are generated for the two-dimensional video frame. A foveated region of interest for the two-dimensional video frame is defined based on a given view orientation. DCT (Discrete Cosine Transform) coefficients are generated for the macroblocks. View adaptive DCT domain filtering is then performed on the DCT coefficients using the foveated region of interest. Quantization offset is calculated for the DCT coefficients using the foveated region of interest. The DCT coefficients are quantized using the quantization offset to generate encoded two-dimensional video frame for the view orientation. A new view orientation is then set as the given view orientation and steps of generating, performing, calculating, and quantizing are performed for each view orientation and each video frame to generate view optimized video.
