The basis for the high-level interpretation of observed patterns of human motion still relies on motion segmentation. Popular approaches based on background subtraction use colour information to model each pixel during a training period. Nevertheless, a deep analysis on colour segmentation problems demonstrates that colour segmentation is not enough to detect all foreground objects in the image...

Background: The use of knowledge of indigenous people in the use of plants can provide valuable information in the field of nutrition, treatment, and provide the basis for the production of drugs used in modern medicine. Objectives: The present study aimed to evaluate the level of recognition of the Ardestanian people to the medicinal plants of the region and introduction to some poisonous pla...

Background & objectives: Since many plants have high efficiency in absorbing heavy elements, the use of phytoremediation is of great importance. The purpose of this study is to identify native plants that absorb heavy metals. Also, the possibility of using them in phytoremediation technology in soils contaminated with heavy metals (around the petrochemical industry of Razi fertilizer in Tehran ...

We introduce a novel technique for summarizing a short video to a single image, by augmenting the last frame of the video with comic-like lines behind moving objects (speedlines), with the goal of conveying their motion. Compared to existing literature, our approach is novel as we do not attempt to track moving objects nor to attain any high-level understanding of the scene: our technique is th...

This paper presents a new approach for moving detection in complex scenes. Different with previous methods which compare a pixel with its own model and make the model more complex, we take an iterative model-sharing strategy as the process of foreground decision. The current pixel is not only compared with its own model, but may also compared with other pixel’s model which has similar temporal ...

background & aim: knowledge of the traditional application of plants is declining faster than the plants themselves; this study was conducted to record and store the local knowledge and cultural outcomes for using the medicinal plants in treating diseases in mobarakeh region, isfahan, iran. experimental: this study has done based on applying the desert survey, information of local people, a...
