An Image Salient Regions Extraction Algorithm Based on Region Growing
Xiaoxiao Wang · Computer Knowledge and Technology · 2013
An improved color image salient region extraction algorithm based on region growing is proposed in this paper.The algorithm improves the performance of initial segmentation by utilizing Watershed on color gradient image.Take salient maps and boundary strength based on the regions into account,proper seeded regions are selected.In the process of region growing,three function to evaluate the capacity of region growing is revised,aiming at measuring the similarity of low features of adjacent regions,the relative position between regions and subjects,and the degree of compact connection.The experimental results dem onstrate that this algorithm is simple,fast and is able to extract the salient regions in line with the characteristics of the human visu al system.
