Digital preservation requires a strategy for the storage of large quantities of data, which increases dramatically when dealing with high resolution images. ...
Wavelet compression of JPEG 2000 produces a high quality image: it is an acceptable alternative to TIFF and a good strategy for the storage of large image assets. ...
But we do not have to provide solutions only in our cultural institutes: the digital assets created in our society in everyday life will eventually become a part of the cultural heritage. ...

The overall compression efficiency highly depends on the approximation accuracy of occupancy probability of each MP-POV. ...
Background Usually, the compression efficiency of visual data, e.g., a pixel in a 2D image or a point in a point cloud, is closely related to its entropy probability approximation conditioned on autoregressive ...
