Social photo-sharing sites like Flickr contain vast amounts of latent information about the world and human behavior. We describe our recent work in building automatic algorithms that analyze large collections of imagery in order to extract some of this information. At a global scale, we show how geo-tagged photographs can be used to identify the most photographed places on Earth, as well as to...

We present a discussion of the precision for the PHOTOS Monte Carlo algorithm, with improved implementation of QED interference and multiple-photon radiation. The main application of PHOTOS is the generation of QED radiative corrections in decays of any resonances, simulated by a “host” Monte Carlo generator. By careful comparisons automated with the help of the MC-TESTER tool specially tailore...

Near-duplicate detection techniques are exploited to facilitate representative photo selection and region-of-interest (ROI) determination, which are important functionalities for efficient photo management and browsing. To make near-duplicate detection module resist to noisy features, three filtering approaches, i.e., point-based, region-based, and probabilistic latent semantic (pLSA), are deve...

We tested a prediction that females' duration estimates of briefly-viewed male, but not female, photos would be modulated by attractiveness. Twenty-seven female participants viewed sequences of five stimuli of identical duration in which the first four were sine-wave gratings (Gabor discs) and the fifth was either the same sine-wave grating (control trials) or a photo of an attractive or unattr...

Erratum Upon publication of the original article [1], the incorrect figure was included as Fig. 8. Additionally, the following paragraph found in Results, under the subheading; Weekend clubs: social mediainstagram “The number of photos acquired was 937 in total, but the top 3 contributors (1 girl and 2 boys) uploaded 70% of the photos, as shown in Fig. 8” should read “ The number of photos acqu...

Attractive people are considered by others to have many positive qualities and in the case of social skills and intelligence, these attributions are often true. In internet dating, individuals with attractive profile photos are viewed more favorably overall, but no research has yet established whether they indeed have more positive qualities. We addressed this issue by having 50 women independe...

Abstract. The paper aims at discussing the accuracy of perspective restitution from view camera photos; cameras are non-standard frequently used in past century for on field shooting buildings and urban sites; this is why reconstruction lost often deals with photos taken a camera. case study chosen proposed experiment an complex built Palermo ‘50s. site features very regular layout surfaces rig...
