Geodesic active contour model is an effective method for the contour detection of multiple objects on an image.However
there are some limitations and shortcomings in this model
such as poor convergence to boundary concavities
leaking from broken boundary
miserable anti-noise ability
etc.In this paper
based on a detail analysis of geodesic active contour
a new algorithm combined the attraction field regularization and multiscale method is presented to overcome these shortcomings.The regularization of the attraction field extends the attraction range and smoothes the field that can decrease the noise influence.The multiscale method provides an accurate contour detection.The final experiments prove that this new model is sensitive to concave boundary
