Visual cryptography encodes a secret binary image (SI) into shares of random binary patterns. The decoding process of a visual cryptography scheme, which differs from traditional secret sharing, does not need any cryptographic algorithms like symmetric and asymmetric algorithms. Visual cryptography is based on the images and is obtained by sending pixel information and stacking of pixels for re...

Modern stereoscopic 3DTV brings new QoE (quality of experience) to viewers, which not only enhances the 3D sensation due to the added binocular depth, but may also induce new problems such as visual discomfort. Subjective quality assessment is the conventional method to assess the QoE. However, the conventional perceived image quality concept is not enough to reveal the advantages and the drawb...

BACKGROUND In the present study we evaluated the functional success after macular hole surgery in correlation to visual quality of life and looked for predictive factors determining surgical success. METHODS Fifty-nine patients that underwent pars plana vitrectomy for idiopathic macular hole were included. Follow-up visits were performed in regular intervals after surgery and included a clini...

middle of squares, one of the components of physical aspect is considered as an appropriateindicator in designing successful urban squares, which consequently promotes visual quality. the present study aims todetermine how the above mentioned aspect was presented in the middle-ages and renaissance within italian squares.considering the aim of the investigation, library studies as well as visual...

in developing countries, it is common to site (or locate) industries without environmental impact assessment. in this study the impacts of two food processing industries on land use and land capability, noise and vibration, environmentally sensitive areas and visual quality as environmental elements were investigated. the research method adopted was the investigative survey research approach (i...

The visual quality assessment approaches and their classification are introduced. Recent developments on both image and video quality metrics, as well as several publicly available databases for both images and videos, are reviewed. Then, we conduct experiments on image and video quality databases to compare the performance of some existing state-ofthe-art visual quality metrics. It is shown th...

Creative processes are nuanced and dynamic. They differ from person to person, based on task and environment. It is important to characterize aspects of the creative process, the actions performed, as a way to gain insight about building better applications and pedagogy. Qualitative methods can help provide rich understanding of creative processes, but require as many as 10 hours of work to tra...
