Abstract
A processing device receives, from an upstream device, a D-dimensional vector data set of media content, wherein D is greater than or equal to one. The processing device applies a low-frequency-pass method to the received D-dimensional media content to generate a low-frequency D-dimensional vector data set of media content. The processing device obtains a structure tensor field comprising a set of D-dimensional structure tensors corresponding to each vector of the received D-dimensional media content. The processing device performs an eigensystem analysis for each structure tensor in the field of structure tensors to generate a plurality of D eigenvalue fields comprising D eigenvalues for each vector of the received D-dimensional media content. The processing device interpolates between each vector of the received D-dimensional media content and a corresponding vector from the low-frequency D-dimensional media content in view of one or more of the D eigenvalues for each vector of the plurality of D eigenvalue fields to produce a restored-dynamic range D-dimensional vector data set of media content.
