As demand for advanced photographic applications on hand-held devices grows, these electronics require the capture of high quality depth. However, under low-light conditions, most devices still suffer from low imaging quality and inaccurate depth acquisition. To address the problem, we present a robust depth estimation method from a short burst shot with varied intensity (i.e., Auto Bracketing)...

Texture plays an important part in many Content Based Image Retrieval systems. This paper describes the results from a human study, which asked 30 volunteers to classify images from the Brodatz Textures album. We use these results to derive a subset which show good agreement among the different individuals. The results for this subset were used to evaluate the retrieval performance of a range o...

In this demonstration, we present the Automatic Linguistic Indexing of Pictures (ALIP) system. The system annotates images with linguistic terms, chosen among hundreds of such terms. The system uses a wavelet-based approach for feature extraction, a statistical modeling process for training, and a statistical significance processor to annotate images. We implemented and tested our ALIP system o...

Simple tone reproduction methods such as the Reinhard global photographic tonemapping operator are popular methods for mapping high-dynamic range images to a lowdynamic range display. However, these methods deal mainly with how luminance is mapped; much less attention has been paid to how a full RGB color is produced. We introduce a simple method, inspired by traditional photography’s use of po...

Many interactive single-user image display applications have prohibitively large bandwidth requirements. However, bandwidth can be greatly reduced by using gaze-contingent multi-resolution displays (GCMRDs) that put high-resolution only at the center of vision based on eye position. A study is described in which photographic GCMRD images were filtered as a function of contrast, spatial frequenc...

When high-resolution, copyrighted photographic images are displayed on the Internet, they must be protected from being copied by screen capture or by file. HTML and a Web browser alone do not provide protection, e .g., screen capture by a standalone program can not be prevented. This paper describes a Java system that provides copy protection for Internet display of photographic images organize...

Shadows may be formed on stained glass windows by structural bars supporting the leaded panels, or by external protective wire grilles, or by masonry, such as mullions or buttresses, or external objects, such as trees. The eye tends to ‘‘discount’’ such shadow formations when viewing the actual windows even though in the photographic images they are very clearly visible. This article introduces...
