Seam-carving has achieved the most widespread use with the blossom of content-aware resizing methods. This paper proposes the video retargeting method where the aspect ratio and the size of the video are reduced. It deals with the spatial and temporal coherence for the purpose of resizing videos. The proposed algorithm is mainly based on matching-area-based temporal energy adjustment. Each fram...

In this paper we discuss a visual interface for presenting large images on small screen devices. We use the seam carving algorithm as an example technique to improve the readability of images, experimenting with it in various ways. We explain the results of a pilot study where we examined the use of seam carving algorithms on a small screen, making comparisons with simple other image processing...

Coal seam gas drainage is affected by many factors which may be generally divided into two groups, geological factors and operational factors. Studies conducted in the Bulli seam found geological factors had a dominant impact on coal seam gas drainage while operational factors had a secondary impact, affecting the amount of optimum gas drainage performance achieved within the limitations impose...

pucker grade is one of the most important quality parameters in garments manufacturing industry. At present, seam pucker is usually evaluated by human inspectors, which is subjective, unreliable and time-consuming. Instead of subjective evaluation, this paper presents an objective method by using image analysis and pattern recognition. The evaluation system consists of image acquisition, image ...

The evolutionarily conserved Wnt/β-catenin signaling pathway plays a fundamental role during metazoan development, regulating numerous processes including cell fate specification, cell migration, and stem cell renewal. Wnt ligand binding leads to stabilization of the transcriptional effector β-catenin and upregulation of target gene expression to mediate a cellular response. During larval devel...

The purpose of this study was to evaluate the large-scale structure, and hence available reserves, of the Lower Cretaceous Luscar Formation near Mountain Park, in the Foothills of Alberta. Coal resource evaluation clearly requires information on the mineable tonnages, as well as the grade, of the coal strata. In open pit mining, the volume of coal economically extracted from a seam is directly ...

Laser welding requires quite high trajectory accuracy of articulated welding robot. To increase this dynamic trajectory accuracy, a novel 3D seam tracking method is proposed based on stereo visual feedback control, in which a key task is to detect the seam from the vision image. To improve the precision and efficiency of the GPI seam-detecting method, this paper proposed a new method, the multi...

The automatic weld seam tracking is an important challenge in None Destructive Testing (NDT) systems for welded pipe inspection. In this Study, a machine vision based seam tracker, is developed and implemented, instead of old electro-mechanical system. A novel algorithm based on the weld image centered is presented, to reduce Environment conditions and improve the seam tracking accuracy. The we...
