We developed the concept of temporal depth imaging and defined non-flat signals as signals with different dispersion values as a function of time. We demonstrated how shifting the timing of a time lens makes it possible to retrieve the dispersion value of each point in the signal, which is equivalent to a 3D imaging system. Finally, we demonstrated how

Probing depth in monocular images
Biological Cybernetics, 1987It is generally expected that depth (distance) is the internal representational primitive that corresponds to much of the perception of 3D. We tested this assumption in monocular surface stimuli that are devoid of distance information (due to orthographic projection and the chosen surface shape, with perspective projection used as a control) and yet ...

Structural Modeling from Depth Images
IEEE Transactions on Visualization and Computer Graphics, 2015In this work, we present a new automatic system for scene reconstruction of high-level structural models. We start with identifying planar regions in depth images obtained with a SLAM system. Our main contribution is an approach which identifies constraints such as incidence and orthogonality of planar surfaces and uses them in an incremental ...

Imaged Depth Versus True Depth
Proceedings, 2015Summary The use of the term ‘velocity’ to describe both the true propagation velocity and the modelling “velocity” used in processing (what is here termed ‘pro-velocity’) has given rise to a damaging level of confusion whereby a great majority of geoscientists take the depth image to be a good representation of depth in the subsurface. The relationship

Depth annotations: Designing depth of a single image for depth-based effects
Computers & Graphics, 2018We present a novel pipeline to generate a depth map from a single image that can be used as input for a variety of artistic depth-based effects. In such a context, the depth maps do not have to be perfect but are rather designed with respect to a desired result.

Image dehazing aims to remove the haze noise and restore the image content from hazy images. It is a challenging task because of the unbalanced distribution of the haze noise and the variety of the image contents. Most existing methods apply convolutional neural networks to learn the dehazing process by blind end-to-end training, which relies on the ...

Depth imaging with multiples is a prestack depth migration method that uses multiples as the signal for more accurate boundary mapping and amplitude recovery. The idea is partially related to model‐based multiple‐suppression techniques and reverse‐time depth migration.

The production of three-dimensional data is the primary function of Kinect. It is up to you to create exciting experiences with the data. A precondition to building a Kinect application is having an understanding of the output of the hardware. Beyond simply understanding, the intrinsic meaning of the 1’s and 0’s is a comprehension of its existential ...

Depth-focused interior echo imaging
IEEE Transactions on Image Processing, 1999This paper is concerned with an echo imaging system which utilizes focused beams of an aperture along a specific contour, for example, a line or a circular arc, in both the transmit and receive modes for data collection. Such data collection strategies are useful for imaging internal structures of a target which are located at a certain depth relative ...

In many areas, depth imaging of seismic data is required to construct an accurate view of the reservoir structure. This is especially true in areas of complex geology and areas with salt tectonics. Having identified the reservoir structure, we of course want to extract further information on lithology, reservoir quality, and fluids.
