3D reconstruction of geo-objects from their digital images is a time-efficient and convenient way of studying the structural features of the object being modelled. This paper presents a 3D reconstruction methodology which can be used to generate photo-realistic 3D watertight surface of different irregular shaped objects, from digital image sequences of the objects. The 3D reconstruction approac...

This paper proposes a efficient method for instant photo aesthetics quality assessment that can be implemented on general portable devices. The classification performance is guaranteed to 0.89 on benchmark photo database. We also port our method onto a middle-level tablet computer to execute instantly and we find it reaches good acceptable efficiency. Moreover, an aesthetic information display ...

UNLABELLED  Traditional wound tracing technique consists of tracing the perimeter of the wound on clear acetate with a fine-tip marker, then placing the tracing on graph paper and counting the grids to calculate the surface area. Standard wound measurement technique for calcu- lating wound surface area (wound tracing) was compared to a new wound measurement method using digital photo-plan...

home video analysis, video to photo, video printing, camera motion analysis, intelligent keyframe extraction, video panorama, superresolution, user intent, motion mining More and more home videos have been generated with the ever growing popularity of digital cameras and camcorders. In many cases of home video, a photo, whether capturing a moment or a scene within the video, provides a compleme...

This paper presents a method of converting a 2D still photo containing the head & shoulders of a human (e.g. a passport photo) to pseudo-3D, so that the depth can be perceived via stereopsis. This technology has the potential to be included in self-serve photo booths and, also as an added accessory (i.e. software package) for digital still cameras and scanners. The basis of the algorithm is to ...

In recent years the growth of popularity of digital photography, together with the development of services and technologies to annotate and organize data on the Web, have extended the possibilities for managing and sharing large numbers of pictures. Our work explores the kinds of metadata that can be captured at the time a photo is taken, and ways to share these metadata in order to build a bro...

This paper proposes a simple yet effective face sketch synthesis method. Similar to existing exemplar-based methods, a training dataset containing photo-sketch pairs is required, and a K-NN photo patch search is performed between a test photo and every training exemplar for sketch patch selection. Instead of using the Markov Random Field to optimize global sketch patch selection, this paper for...

With digital still cameras, users can easily collect thousands of photos. Our goal is to make organizing and browsing photos simple and quick, while retaining scalability to large collections. To that end, we created a photo management application concentrating on areas that improve the overall experience without neglecting the mundane components of such an application. Our application automati...

In this paper we discuss an application of CMOS photo-sensor array chip using pulse frequency modulation (PFM) to sub-retinal implantation to recover human vision. PFM with integration mode as photo-sensing circuit is used to realize enough dynamic range and compatibility with signals in real retina. To effectively stimulate the retinal cells, we have designed a PFM circuit with limited bandwid...

Current and future seniors are more and more active users of computers, mobile technology, and the internet. They also have a need to communicate and keep in touch with their family, relatives, friends, and their peers. The elderly are also very active in creating and sharing media in the form of photographs, photo albums, and family histories. Based on our user studies in online photo sharing ...
