结合对比特性与局部清晰特性的图像显著区域检测

为了有效地确定图像中的重要区域，文中根据人眼视觉关注中自上而下和自下而上的两种特点，提出了一种结合图像对比特性与清晰区域的显著检测方法. 图像中颜色的全局和局部对比引起低级视觉关注，而图像的清晰部分通常对应于拍摄时所关注的对象，反映高级视觉特性. 采用颜色分类和检测图像细节区域的方法分别提取了两类显著图，并将它们组合起来. 实验结果表明，通过综合考虑两种视觉特性得到的显著图，对多类图像都能较好地检测出与人眼视觉关注相吻合的区域.

Image Saliency Detection Based on Contrast Features and Local Sharpness

To extract important areas in an image that attract visual attention,a saliency detection scheme using both contrast features and local sharpness in the image is proposed.The local sharpness is related to the focusing status,which reflects the human judgment of the scene being imaged.Therefore,the presented method integrates two different visual characteristics,which we call low- and high-level human visual attention (HVA).The globe and local color contrast in the image arouse the low-level HVA,whereas the ...
