IMAGE TESSELLATION FOR REGION-SPECIFIC COEFFICIENT ACCESS

摘要

The present technique addressably handles image data (402), which isdecomposed andtessellated into a plurality of tessellated sub-band blocks (430, 474, 516).Thetessellated sub-band blocks (430, 474, 516) may be addressed by an array ofindices,which identify specific data blocks of the image data (402) by decompositionleveland spatial coordinates of the tessellated sub-band blocks (430, 474, 516).Accordingly, a desired region (604, 672, 700) of the image data (402) atmultipleresolutions can be identified and individually handled for storage,transmission,retrieval, and display. The desired region (604, 672, 700) also can bereferencemarked based on the array of indices.
