A parametric active contour model is presented for object tracking based on matching degree image of object contour points. We first construct a matching degree image according to object contour points, and track the object using parametric active contours. This paper presents a new feature matching approach and a new directional filter. Assuming that the motion of objects is small in this pape...

This paper proposes a new fundamental frequency(F0) contour control method based on vector representation of F0 contour. The main points of the proposed method are as follows; (1) Desired F0 contours are created by selecting or modifying natural F0 contours held in a speech database. (2) F0 contour selection is based on statistical estimation using a vector representation of F0 contour (3) The ...

In recent years, mutual information has developed as a popular image registration measure especially in multimodality image registration. For different modality medical images, the contour of tissues or organs is similarity. In this paper, an effective new registration method of the multimodal medical images based on the contour mutual information is proposed. Firstly, get the contour through v...

Active contour models based on local region fitting energy can segment images with intensity inhomogeneity effectively, but their segmentation results are easy to error if the initial contour is inappropriate. In this paper, we present a simple and universal method of improving the robustness of initial contour for these local fitting-based models. The core idea of proposed method is exchanging...
