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...

Visualization for structures of architectural significance and objects of importance to the World’s cultural heritage has recently been receiv ing more attention. Generally, TIN and Marching Cube algorithm are used as popular modelling method for these objects. When TIN is used, to connect all the measured points, there is a problem of connecting the object which must originally deviate and mus...

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 ...

3D city modelling from airborne imagery includes mainly two parts: (1) image processing procedures and (2) 3D modelling for manmade objects such as buildings, roads and other objects. Line extraction and stereo matching are usually utilized as an image processing procedures. However, there are some issues for automatic man-made object modelling. In particular, spatial data acquisition of buildi...

Traditional virtual reality environments are based on rendering all the surroundings using 3D models of objects. This requires graphically modelling the whole environment, which is usually a long and tedious task. 360-degree cameras that have recently become commercially available might be able to change that situation, as image-based virtual reality requires no graphical modelling and therefor...

We propose a sweep-based approach to the freeform deformation of three-dimensional objects. Instead of using a volume enclosing the whole object, we approximate only its deformable parts using sweep surfaces. The vertices on the object boundary are bound to the sweep surfaces and follow their deformation. Several sweep surfaces can be organized into a hierarchy so that they interact with each o...
