... recovers 3D shape of an object from a serial 2D images. Due to the definite depth of field, the whole image shot by a single camera cannot be completely focused. Hence, the fundamental to the concept of reconstructing by focus analysis is the relationship between focused and defocused images of an object...

...Tao Liu; Zhixiang Fang; Qingzhou Mao; Qingquan Li; Xing Zhang Purpose The spatial feature is important for scene saliency detection. Scene-based visual saliency detection methods fail to incorporate 3D scene spatial aspects. This paper aims to propose a cube-based method to improve saliency...
