Change detection using a statistical model in an optimally selected color space
We present a new noise model for color channels for statistical change detection. Based on this noise modeling, we estimate the distribution of Euclidean distances between the pix...

On Measuring Process Model Similarity Based on High-Level Change Operations
For various applications there is the need to compare the similarity between two process models. For example, given the as-is and to-be models of a particular business process, we ...
