Multi-cut light field depth estimation

2015 3rd IAPR Asian Conference on Pattern Recognition (ACPR), 2015
We investigate the problem of depth map estimation of a scene from 4D light-field data. Unlike prior work, we process all the input images (or sub-images) of the light-field. Indeed, for each point of the scene, different depth candidates are estimated by considering all possible 3D light-field cuts instead of only 2, i.e.

Influence of Cutting Parameters and Interactions on the Depth of Cut in Continuous Mining Operation

Advanced Materials Research, 2012
During mechanized continuous mining, the depth of cut (DOC) of picks on the drum directly affects the forces exerted on the picks, as well as the forces and torque acting on the drum. Therefore, accurate analysis of DOC of individual picks is needed to optimize the design of the drum and the operation of the continuous mining machine.

Cut-Elimination with Depths

2020
In this chapter we first introduce a standard cut-elimination procedure for the first-order logic and the \(\omega \)-logic, by which we see that the tree-height of the resulting cut-free proofs is bounded by a tower of exponential functions. Such a control of the tree-heights in cut-elimination is one of the most important results in ordinal analysis.

An experimental method for studies of intermittent cutting at small cutting depths

International Journal of Machine Tools and Manufacture, 1988
Abstract Most devices for metal cutting experiments are designed to simulate continuous cutting at relatively large cutting depths. However, there is also a need for techniques to study the more complex situations prevailing in other important cutting operations like milling, sawing, hobbing, shaper cutting and grinding.

Cutting planes and constant depth Frege proofs

[1992] Proceedings of the Seventh Annual IEEE Symposium on Logic in Computer Science, 2003
The cutting planes refutation system for propositional logic is an extension of resolution and is based on showing the nonexistence of solutions for families of integer linear inequalities. The author defines a modified system of cutting planes with limited extension and shows that this system can polynomially simulate constant-depth Frege proof ...

Stereo estimation of depth along virtual cut planes

2011 IEEE International Conference on Computer Vision Workshops (ICCV Workshops), 2011
Stereo vision is broadly employed in robotics and intelligent vehicles for recovering the 3D structure of the environment. The scene depth is typically estimated by triangulation after associating pixels between views using a dense stereo matching approach. In the last few years, the image resolution has steadily increased due to the advances in camera

Effect of Cutting Tool Properties and Depth of Cut in Rock Cutting: An Experimental Study

Rock Mechanics and Rock Engineering, 2018
The current paper is designed to investigate the effect of worn (blunt) polycrystalline diamond compact cutter properties on both the contact stress ( $$\sigma$$ ) and friction coefficient (μ) mobilized at ...

Depth image in-loop filter via graph cut

2016 IEEE International Conference on Image Processing (ICIP), 2016
With the ability of representing 3D scene geometry, depth maps are used to synthesize virtual views in free view video (FVV) or 3DTV. However, compression artefact of the depth images always lead to seriously geometry distortions in synthesized view, which severely affects the visual perception of 3D display.

Influence of Cutting Compound on Critical Cut Depth of Glass BK7

Key Engineering Materials, 2013
In diamond cutting of optical glasses, the magnitude of critical depth of cut for brittle-ductile transition is an important factor affecting the machinability of the work material in terms of production rate and surface quality. In this work, scratching tests with increasing depths of cut were conducted on glass BK7 to evaluate the influence of the ...
