Description of the application:

The tool localization method is based on model fitting using RANSAC (RNS) and two models of tool in 3D US have been proposed (RNS+AxShp, RNS+IntDstr) in [1]. A method RNS+LineFilter does line filtering to enhance contrast between needle and background has been proposed in [2]. The models IntDstr and LineFilter were learned on training data, while the model AxShp does not use any learning. Note that for a question of speed the method RNS+LineFilter is reading line-filtered data from the file computed in pre-processing.
