Smart phones, as one of the most important platforms for personal communications and mobile computing, have evolved with various embedded devices, such as cameras, Wi-Fi transceivers, Bluetooth transceivers and sensors. Specifically, the photos taken by a smart phone has the approximate or even equivalent image quality to that of a professional camera. As a result, smart phones have become the ...

When people rapidly judge the truth of claims presented with or without related but nonprobative photos, the photos tend to inflate the subjective truth of those claims--a "truthiness" effect (Newman et al., 2012). For example, people more often judged the claim "Macadamia nuts are in the same evolutionary family as peaches" to be true when the claim appeared with a photo of a bowl of macadamia...

Participants were shown three photos with different subjects and colour casts, and were asked to rate four given emotions on a scale from zero to five for each photo. Results look promising; a negative colour cast causes far less positive responses and more negative responses f...

This paper presents how cross-media correlation facilitates summarization of photos and videos captured in journeys. Correlation between photos and videos comes from similar content captured in the same temporal order. We transform photos and videos into sequences of visual word histograms, and adopt approximate sequence matching to find correlation. To summarize photos and videos, we propose t...

Growing prevalence of smartphone makes photography easier than ever. However, the quality of photos varies widely. Because judging the aesthetic of photos is based on several "rule-of-thumb", it remains difficult for computers to rate photos without manual intervention. In this work, we utilize aesthetic features of photos and machine learning techniques to automatically distinguish good photos...

Recently, cloud storage and processing have been widely adopted. Mobile users in one family or one team may automatically backup their photos to the same shared cloud storage space. The powerful face detector trained and provided by a 3rd party may be used to retrieve the photo collection which contains a specific group of persons from the cloud storage server. However, the privacy of the mobil...
