This paper proposes automatic representations of spatial relationships among photos for structure analysis and review of a photographic subject. Based on camera tracking, photos are shown in a 3D virtual reality space to represent global spatial relationships. At the same time, the spatial relationships between two of the photos are represented in slide show sequences. This proposal allows peop...

As digital photography rapidly replacing the traditional film photography as the photography of choice for all but a few devoted professionals, post image processing of natural color photos such as denoising becomes increasingly an integral part of digital photography. Although many denoising schemes have been designed, almost none specifically target natural color photos. Noise in natural colo...

Building models are conventionally reconstructed by measuring their vertices point-by-point in a digital photogrammetric workstation (DPW), which is time and labor consuming process. Although aerial photos implicitly provide 3D information of buildings, LiDAR systems directly provide high density and accurate point cloud coordinates. However, LiDAR data cannot accurately represent the building ...

The purpose of this work is to implement panorama stitching from a sequence of photos taken by cell phone camera on the Android phone system. The photos for panorama stitching are captured in a fixed linear spatial interval based on magnetic compass provided by Android cell phone. The computation is carried out either on phone or by a cloud according to the number of photos used for the panoram...

Provision of historical information based on geographical location represents a new scope of connecting the present of a certain location or landmark with its history through a timescape panorama. This may be achieved by exploring a linear timeline of photos for certain areas and landmarks that have both historic and modern photos. Matching modern to historical images requires a special effort ...

With rapid advances in sensor, storage, processor, and communication technologies, consumers can now afford to create, store, process, and share large digital photo collections. With more and more digital photos accumulated, consumers need effective and efficient tools to organize and access photos in a semantically meaningful way without too much manual annotation effort. From user studies, we...

Photos lead people to believe that both true and false events have happened to them, even when those photos provide no evidence that the events occurred. Research has shown that these nonprobative photos increase false beliefs when combined with misleading suggestions and repeated exposure to the photo or target event. We propose that photos exert similar effects without those factors, and test...

The uptake of digital photos vs. print photos has altered the practice of photo-sharing. Print photos are easy to share within the home, but much harder to share outside of it. The opposite is true of digital photos. People easily share digital photos outside the home, e.g., to family and friends by e-mail gift-giving, and to social networks and the broader public by web publishing. Yet within ...

We propose an algorithm for automatic photo selection for media and entertainment applications like photobook and slide-show. The technique comprises three main steps: photo quality estimation and elimination of poor-quality photos, adaptive quantization of survived photos in time-camera plane, and selection of the most appealing photos from each quantized group. For detection of low-quality ph...

The WHO is committed to eliminating trachoma as a public health concern by 2020. Since decisions for mass treatment are determined by the prevalence of clinical trachoma in a community, efficient and accurate methods for monitoring clinical activity remain a priority. However, reliability of clinical examination is poor and disagreement between graders is common. Photography of the conjunctiva ...
