融合局部图像信息的SLGS活动轮廓模型
SLGS Active Contour Model Fused with Local Image Information
摘要
Abstract
The SLGS model can not deal with intensity inhomogeneity, while the RSF model is sensitive to initialization. Incorporating the local information defined by the RSF model into the SLGS model, this paper proposes a novel active contour model in a partial differential equation formulation. A signed pressure force function is defined by a linear combination of the global fitting values defined by the SLGS model and the local fitting values defined by the RSF model. By choosing appropriately the parameter that controls the influence of the global and local fitting values, the proposed model can efficiently deal with intensity inhomogeneity and allows for the flexible initialization. Experimental results show that the proposed model is more accurate than the SLGS model.关键词
