This article presents a method for automatic seam-tracking in friction stir welding (FSW) of lap joints. In this method, tracking is accomplished by weaving the FSW tool back-and-forth perpendicular to the direction of travel during welding and monitoring force and torque signals. Research demonstrates the ability of this method to automatically track weld seam positions. Additionally, tensile ...
This paper deals with a fundamental method of automatic assessment of the appearance of seam puckers (SP) on suits. Taking the fractal dimensions of SPs as features, we process the problem as pattern recognition. Twenty suits were used for the evaluation experiment and we could obtain a result close to the human inspection. The result was also compared to the evaluation of our previous paper, w...
In this supplementary material we first (Section 2) describe the details of a variant of scene carving (Sc. Carve-D.) not fully described in the paper but mentioned in Sect. 5.2 and Fig. 8(f) and Fig. 8(g). This algorithm aims to minimize the visible distortion in the next image, in contrast to the scene carving algorithm (Sc. Carve) we present in the paper in which the distortion in the backgr...
An increasing amount of display devices with fixed sizes call for an adaptive strategy for optimal display. For this purpose, content aware image resizing techniques are developed. Previous works mainly lay their attention on the shrinkage operation of the examined image. Less efforts are paid on the expansion manipulation. Though some literatures claim an extension of their shrinkage operation...
The symbiotic branching model describes a spatial population consisting of two types that are allowed to migrate in space and branch locally only if both types are present. We continue our investigation of the large scale behaviour of the system started in [BHO15], where we showed that the continuum system converges after diffusive rescaling. Inspired by a scaling property of the continuum mode...
Content-aware image retargeting has drawn much attention in image and vision research in recent years. However, existing methods are very difficult to ensure that the result images from retargeting achieve good visual effect on the whole, since these methods mainly focus on spatial image information. In this paper, we propose a new approach on content-aware image retargeting based on visual eff...
Seam carving has been widely used for contentaware resizing of images and videos with little to no perceptible distortion. Unfortunately, for high-resolution videos and large images it becomes computationally unfeasible to do the resizing in real-time using small-scale CPU systems. In this paper, we exploit the highly parallel computational capabilities of CUDA-enabled Graphics Processing Units...
Seam carving is a representative content-aware image retargeting approach to adjust the size of an image. To preserve visually prominent content, seam-carving algorithms first calculate connected path pixels, referred as seam, according defined cost function and then by removing or duplicating repeatedly calculated seams. actively exploited overcome diversity in resolution images between applic...
A recently proposed approach, called seam carving, has been widely used for content-aware resizing of images and videos with little to no perceptible distortion. Unfortunately, for high-resolution videos and large images it is not computationally feasible to do the resizing in real-time using small-scale CPU systems. In this paper, we exploit highly parallel computational capabilities of CUDA-e...
This paper presents a novel image retargeting approach for ranging cameras. The proposed approach first extracts three feature maps: depth map, saliency map, and gradient map. Then, the depth map and the saliency map are used to separate the main contents and the background and thus compute a map of saliency objects. After that, the proposed approach constructs an importance map which combines ...
