Along with the advancement of technology, image display devices such as mobile phones, computers and televisions are ubiquitous everywhere in our lives. Due to the different sizes of display devices, digital image scaling technology is often used on the devices while presenting images. For example, when large-size photos are viewed on mobile phones, they tend to present as scaled-down images of the entire pictures, making the main subjects quite small and thus causing inconvenience for viewers. On this account, this study has offered an efficient and high-quality intelligent content-aware image resizing system to solve this problem. This system will first analyze the main area of the image, and then applies an intelligent compression process on the entire image. By doing this, images can still have a complete main subject even after being compressed, not only achieving an excellent visual effect while making the main subject more prominent and obvious, but also reducing the data volume of images. Except for various sizes of display devices, this technology can also be applied on video transmission (H.264/AVC) to effectively reduce the data volume of images, making a substantial contribution to both the image scaling and video coding.

Biodiversity is a concurrent part of the nature inheritance. The human’s activity (development of cities, industry, agriculture, transport infrastructure, pollution, etc) is influencing the nature’s disbalance. Natural areas of habitats are on the way to disappear or their status is getting worse. There is a need for special means to ensure the protection of many species of fauna and flora and their natural habitats, because they are in danger of disappearing. The network “Natura 2000” has few goals: to cover the fragile and valuable natural habitats and species of particular importance for the conservation of biological diversity within the territory of EU and to guarantee sustained efforts to protect the most important areas properly. The main objective of the “Natura 2000” network is to ensure the survival of species that are threatened or rare throughout Europe. These legal EU documents ensure the creation of the above-mentioned European network of protected territories in public territories as well as in private lands. Economic and farming activities are restricted in these areas as a way to protect natural habitats types, rare animals as well as are plants habitats. That way the interests of land owners become quite different from the nature protectionists and the prohibitions of land or forest property rights. It is quite difficult to evaluate the economical loss while establishing some new protected areas in public and private lands. The evaluation is specific for... [to full text]
