The current scale of deforestation in tropical regions and the large areas of degraded lands now present underscore the urgent need for interventions to restore biodiversity, ecological functioning, and the supply of goods and ecological services previously used by poor rural communities. Traditional timber plantations have supplied some goods but have made only minor contributions to fulfillin...
We present a method for binarization of degraded call number images. Based on the texture feature of the character stroke, the algorithm initially detects the character pixels to determine the size of the local area and compute the logical thresholding level. Experimental results prove the effectiveness of the method. key words: call number, degraded image, image binarization, image segmentatio...
ارتباط موقعیت شیب و نوع کاربری در شیب تپههای دارای فرسایش سیلانگل با ضریب فعالیت خاک و حدود آتربرگ
Mudflow erosion is a pervasive problem with adverse consequences for natural ecosystems in most parts of the world. The main factors creating Mudflow erosion are heavy rains, snow and ice melts and flooding rivers. In this study, the effects of slope position and land use type on Mudflow erosion at hill slopes with three different land uses were investigated. For this purpose, three hill slopes...
