Object parameter estimation using Trace transform feature extraction

Presented paper deals with the problem of parameter estimation using Trace transform by which it is possible to obtain parameters of transformations (rotation, translation and scaling) used previously to modify image. System performance was evaluated in experiments with original images and their different modifications. The proposed theory of parameter estimation system provides basis for implementation in C++ programme package.
