We present a novel multi-spectral approach for face recognition using visual imagery as well as the physiological information extracted from thermal facial imagery. The main point of this line of research is that physiological information available only in thermal infrared, can improve the performance and enhance the capabilities of standard visual face recognition methods. For each subject in ...

The visual attention complexity of a scene is regarded as a feature describing many information of the content in a video sequence, which meanwhile plays an important role in various applications to estimate the perceptual quality, information retrieval and so on. In this paper, the hypothesis about visual attention complexity is proposed. The complex video sequence in the view of visual attent...

This paper describes visual interaction mechanisms for image database systems. The typical mechanisms for visual interactions are query by visual example (QVE) and query by subjective descriptions (QBD). The former includes a sketch retrieval function and a similarity retrieval function, and the latter includes a sense retrieval function. We adopt both an image model and a user model to interpr...

The increasing size of structured data that are digitally available emphasizes the crucial need for more suitable representation tools than the traditional textual list of results. A suitable visual representation should both reflect the database’s structure for navigation purpose and allow performing visual analytical tasks for knowledge extraction purpose. In this paper we present a visual na...

In this paper, we present the design and implementation of an integrated object browsing and visual querying system called IVORY(Integrated Visual brOwsing and queRYing system) for object databases. The design goals of IVORY includes provision with a good user interface and compliance to standards. Provision with a good user interface is achieved through IVORY's integrated browsing and querying...

In this paper, we review works related to big visual data on the Web in the literature of computer vision and multimedia research regarding the following points: (1) Web image acquisition for construction of visual concept database for image/video recognition, (2) Web image application for visual concept analysis and data-driven computer graphics, and (3) real-world sensing through Web images t...

A slide-to-lecture-video search system is implemented on Android tablet. The search system gets video clips from the SCPD database. Previous research on Fisher Vector and Residual Enhanced Visual Vector are combined to generate compact index for each database image. An augmented database of clean slide images is used to exploit the temporal redundancy of videos. Original database of video keyfr...

distribution of retinal blood vessels (rbvs) in retinal images has an important role in the prevention, diagnosis, monitoring and treatment of diseases, such as diabetes, high blood pressure, or heart disease. therefore, detection of the exact location of rbvs is very important for ophthalmologists. one of the frequently used techniques for extraction of these vessels is region growing-based se...

This visual essay presents Database (E)state, which is an artist and activist-led PhD research project that explores the role of relational databases in processes urban regeneration. The addresses proposed demolition Cressingham Gardens Estate by Lambeth Borough Council, South West London, UK. By depicting problems associated with accessing, comprehending, creating a resident-controlled ‘Shadow...

linear query representations formulated by e.g. SQL, as evidenced from some empirical studies [4][5][6]. As a consequence, different types of users, especially novices, can learn and use the query facilities in a more intuitive way, without needing to memorize the database schema or the grammar of the query language. Adapting this query mechanism into CASE can benefit CASE users in a similar wa...
