In this study, we developed an algorithm for detecting seam cracks in a steel plate. Seam cracks are generated in the edge region of a steel plate. We used the Gabor filter and an adaptive double threshold method to detect them. To reduce the number of pseudo defects, features based on the shape of seam cracks were used. To evaluate the performance of the proposed algorithm, we tested 989 image...

SUMMARY Seam carving, which preserves semantically important image content during resizing process, has been actively researched in recent years. This paper proposes a novel forensic technique to detect the trace of seam carving. We exploit the energy bias and noise level of images under analysis to reliably unveil the evidence of seam carving. Furthermore , we design a detector investigating t...

Mesh parameterization is a key problem in digital geometry processing. By cutting a surface along a set of edges (a seam), one can map an arbitrary topology surface mesh to a single chart. Unfortunately, high distortion occurs when protrusions of the surface (such as fingers of a hand and horses’ legs) are flattened into a plane. This paper presents a novel skeleton-based algorithm for computin...

The surrounding rock control technology of mining roadways in large inclination seams with a weak structural plane the roof is one most challenging fields underground roadway support. In view serious deformation transportation 1201 working face mine, and failure characteristics instability mechanism are analysed. self-stability mechanical model block structure under support effect established, ...

In this paper, the effects of horizontal stress and dimensions of barrier pillars on the stability of drifts hr been investigated. An elastoplastic hybrid finite/boundary element program has been used. A plastic analysis of stresses in barrier pillars above the drifts in one of the underground coal mines with inclined seams is examined. Computed stresses and safety factor controur lines around ...

The C. elegans epidermis is a simple epithelium comprised of three major cell types, the seam, syncytial and P cells. While specification of all major epidermal cells is known to require the ELT-1 GATA transcription factor, little is known about how the individual epidermal cell types are specified. We report that elt-5 and -6, adjacent genes encoding GATA factors, are essential for the develop...

A novel modeling method for 3D curve welding seam is presented in this paper based on a welding robot for large workpiece. The 3D curve welding seam tracking is implemented by macro and micro motion which can control translational motion of torch in a large range and implement accurate seam tracking in small range. As such, the self-teaching seam model and real-time seam model are established t...

In this paper we consider the problem of implementing and optimizing the Seam Carving algorithm on graphics processing units. Seam Carving is a content-aware image resizing method proposed by Avidan and Shamir. In order to use their proposed method in real-time application, a pre-processing step is needed. While some other papers propose real-time resizing by changing the original Seam Carving ...

The context of this paper is Enterprise Architecture (EA). EA is a multi-disciplinary approach that allows different specialists to design new business and IT systems and focuses on the integration of these systems. Our group develops a specific EA method that is called SEAM. The current version of SEAM has a formal denotational semantics for its modeling language. In order to provide model sim...

Caenorhabditis elegans seam cells divide in the stem-like mode throughout larval development, with the ability to both self-renew and produce daughters that differentiate. Seam cells typically divide asymmetrically, giving rise to an anterior daughter that fuses with the hypodermis and a posterior daughter that proliferates further. Previously we have identified rnt-1 (a homologue of the mammal...
