Reconstruction of scene geometry and semantics are important problems in vision, and increasingly brought together. The state of the art in Structure from Motion and Multi View Stereo (SfM+MVS) can already create accurate, dense reconstructions of scenes. Systems such as CMPMVS [2] are freely available and produce impressive results automatically. However, when assumptions break down or there i...

It refers to the problem of automatically filling holes in images left by the unwanted objects removal in a plausible way. Unlike previou...

Image inpainting technique uses structural and textural information to repair or fill missing regions of a picture. Inspired by human visual characteristics, we introduce a new image inpainting approach w...

In this paper, a hybrid inpainting method is proposed for the simultaneous reconstruction of geometry and texture in missing regions of a color image. Using inpainting methods based on partial differential equation (PDE) to fill in large image regions usually fails if these regions contain textures. On the other hand, texture synthesis algorithms sometimes fail due to complex structure and text...

Continuous Vídeo-EEG monitoring remains the gold-standard tool to confirm or disregard the diagnosis of epilepsy in selected cases in which a differential diagnosis is required and not clearly established in the basis of outpatient procedures. However, it may be a tiresome and stressful experience for patients and it is certainly an expensive test. Thus, we wonder how far (considering both fina...

The visual system completes image fragments into larger regions when those fragments are taken to be the visible portions of an occluded object. Kellman and Shipley (1991) argued that this "amodal" completion is based on the way that the contours of image fragments "relate." Contours relate when their imaginary extensions intersect at an obtuse or right angle. However, it is shown here that con...

BACKGROUND Arthroscopic procedures may be technically challenging because of impaired vision, limited space, and the 2-dimensional vision of a 3-dimensional structure. Spatial orientation may get more complicated when the camera is pointing toward the surgeon. HYPOTHESIS Spatial orientation and arthroscopic performance may be improved by simply mirroring the image on the monitor in different ...

The human visual system possesses a remarkable ability to reconstruct the shape of an object that is partly occluded by an interposed surface. Behavioral results suggest that, under some circumstances, this perceptual process (termed amodal completion) progresses from an initial representation of local image features to a completed representation of a shape that may include features that are no...

We give a constructive localic account of the completion of quasimetric spaces. In the context of Lawvere’s approach, using enriched categories, the points of the completion are flat left modules over the quasimetric space. The completion is a triquotient surjective image of a space of Cauchy sequences and can also be embedded in a continuous dcpo, the “ball domain”. Various examples and constr...
