Segmentation of depth image using graph cut

2012 9th International Conference on Fuzzy Systems and Knowledge Discovery, 2012
A large number of tasks in computer vision involve finding a target from a background image. It is also known as the foreground/background discrimination problem. Various methods have been developed to solve this problem. [1, 2, 10, 11, 12] Newly developed techniques for general purpose of object abstraction use both color and edge information for ...

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.

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.

Optimization of working parameters of water jet cutting in terms of depth and width of cut

Proceedings of the Institution of Mechanical Engineers, Part E: Journal of Process Mechanical Engineering, 2011
The purpose of this study is to optimize different operational parameters, such as the nozzle diameter, traverse velocity, standoff distance, and pump pressure, with reference to cutting efficiency parameters, namely, depth and width of cut, in the cutting operation using a pure water jet on Sardinian basalt samples.

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 ...

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 ...

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
