Original Abstract Submitted

Cropping volumetric media is provided. Received volumetric video data is represented by a Bloch sphere. A user selected sub-volume is received to which the volumetric video data is to be cropped. CNNs having different strides are applied to sub-spheres defined within the Bloch sphere. The CNNs generate a correlation score for each sub-sphere relative to a user specified parameter. Best rotation matrices for the sub-spheres are determined to achieve a user specified angle of view, and the sub-sphere correlation scores are optimized according to the best rotation matrices. Cylindrical weights are applied to the sub-spheres according to the optimized correlation scores, and a best solution is selected for the sub-volume according to the correlation scores. The rotation matrices are reflected orthogonally onto the sub-volume, and the sub-volume is cropped from the volumetric video according to the sub-sphere with the highest correlation score to create the cropped image.
