Abstract :
We propose an algorithm to detect ruptures in a signal by means of information criteria along with its application to edge detection on grey-level images. Information criteria are made of two terms: a likelihood term and an original penalization factor. They enable us to find in an optimal way autoregressive models and their number to model the signal. The model changes represent the edges of the objects in the image.
