Hierarchical Contour Closure-Based Holistic Salient Object Detection
2017
IEEE Transactions on Image Processing
Preserved Fulltext
To better compute the saliency for complicated images, we propose a hierarchical contour closure based holistic salient object detection method, in which two saliency cues, i.e., closure completeness and ...
Such fine-grained contrast based salient object detection methods are stuck with saliency attenuation of the salient object and saliency overestimation of the background when the image is complicated. ...
CONTOUR CLOSURE BASED SALIENCY DETECTION The proposed framework is illustrated in Fig. 4 , in which two closure based maps are generated for the salient object detection in the hierarchical segmentation ...

We distinguish three types of configural processing: detecting the first-order relations that define faces (i.e. two eyes above a nose and mouth), holistic processing (glueing the features together into ...
We provide evidence for their separability based on behavioral marker tasks, their sensitivity to experimental manipulations, and their patterns of development. ...
It seems logical that the three types operate in the functional and neural order that we described: detection of the face based on first-order relations as a necessary first step before holistic processing ...

In a typical contour based interactive method, the user first places a contour close to the object boundary, and then the contour will evolve to snap to the nearby salient object boundary. ...
Hence, in some sense general object proposal problem is correlated with the popular salient object detection problem. ...

Using the operator's output, a novel contour-based descriptor is created that extends the shape context descriptor to include boundary ownership information and accounts for rotation. ...
In this work, we argue that by exploiting midlevel contour grouping mechanisms, we are able to effectively address all the above issues in a simple, holistic object-detection framework. ...

Behaviorally, we found that the EF of closure facilitated oddball discrimination on objects, as demonstrated by previous studies, but did not facilitate oddball discrimination on holes with the same shape ...
We predict that configural superiority, which means that the detection of triangles is faster than the detection of bars, may only be effective with objects but not holes. ...
