A framework for evaluating the impact of compression on registration algorithms without gold standard
2008
2008 15th IEEE International Conference on Image Processing
An evaluation of the impact of lossy compression on rigid registration algorithms for medical images is proposed. ...
Due to the lack of gold standard for many clinical problems, the framework relies on a statistical procedure that estimates a reference from a large set of uncompressed images. ...
It is for instance the case of the transformation of the algorithm depicted with a square on figure 1 : compression has brought it closer to the bronze standard without compression. ...
