In this paper, we propose a graph-based model for pupil localization, which is a step towards gaze detection. The proposed model can differentiate the key points located at the eyelashes, eyebrows and eye white regions. We first crop the eye region with an ellipse and then estimate the pupil center within the ellipse, thus reducing the computational complexity. We also consider the light reflections...
In this paper, we propose a variant of the iterative closet point (ICP) registration method by introducing a novel weight-bootstrap scheme. The rigid transform between two point sets can be estimated, as long as proper correspondences are given. The accuracy of the estimated transform is mainly determined by the goodness of these matches. However, the confidence of the correspondences is weakened...
Human beings recognize similarity in scene perception based on their available high-level knowledge about the low-level visual features, which is gradually accumulated throughout their entire lives. Once there is not enough knowledge they tend to rely on low-level visual content. Inspired by this observation, we proposed a new framework of relevance feedback for content-free image retrieval to tackle...
