Image stitching computes geometric transforms to align images based on the best fit of feature correspondences between overlapping images. Seam-cutting is used afterwards to to hide misalignment artifacts. Interestingly it is often the seam-cutting step that is the most crucial for obtaining a perceptually seamless result. This motivates us to propose a seam-driven image stitching strategy wher...

and Alla Heorhiadi In the United States organizational change and development work has a rich history, including the influence of Kurt Lewin, Rensis Likert, Douglas MacGregor, Warren Bennis, the socio-technical tradition of Tavistock, and more recently, work in large scale change, appreciative inquiry and chaos / complexity. In France, a different tradition has evolved, the Socio-Economic Appro...

In some security applications, it is important to transmit just enough information to take the right decisions. Traditional video codecs try to maximize the global quality, irrespective of the video content pertinence for certain tasks. To better maintain the semantics of the scene, some approaches allocate more bitrate to the salient information. In this paper, a semantic video compression sch...

In this paper the main problems and the available solutions are addressed for the generation of 3D models from terrestrial images. Close range photogrammetry has dealt for many years with manual or automatic image measurements for precise 3D modelling. Nowadays 3D scanners are also becoming a standard source for input data in many application areas, but image-based modelling still remains the m...

In this paper two concepts for modelling 3D topography are introduced. The first concept is a very pragmatic approach of 3D modelling, trying to model as much as possible in (less complicated) 2.5D and use 3D modelling only in exceptional cases. The idea is to use a constrained TIN in 2.5D and place 3D TENs on top or below this surface. As both data structures use the same simplexes (nodes, edg...

Gas extraction in the pressure-relief area using depressurization effect of seam mining is an effective way to solve coal-mine gas problems. In this paper, we performed numerical modelling 204 working face via FLAC 3D, by which stress variation rock mass and associated permeability evolution during advancement were investigated. Furthermore, favorable zone for pressure relief was proposed based...

3d imagination of human's organs has become feasible by digital image processing techniques and algorithms via ct or mri images in recent years. in this study, a new method for reverse engineering and biomodelling of hard tissues by catia cloud points' concept has been considered. comparing with the current softwares (e.g. biobuild or mimics) has shown the new method's easiness of implementing ...

INTRODUCTION The proliferation of professional palliative care services in recent years has increased access for people with palliative care needs; however, gaps in services continue to exist, particularly in rural and remote areas of Australia. In order to address one gap in rural health service delivery, the Support, Education, Assessment, and Monitoring (SEAM) Service for regional and rural ...

Three-dimensional (3D) modelling of geological body is an important issue of 3D GIS and 3D Geosciences Modelling, and one of the key technologies of digital mine. GTP model and its components are introduced in this paper. According to the relations between chronolith and rock attribute comprehensively, the modelling region, system, series, group and rock characteristics(RC) are regard as the sc...
