With a cultivated area of over 2x108ha, wheat is the largest crop worldwide by cultivated surface. For wheat crops, the production suffers loss caused by weeds, and depending on the weeding level, the fertilization level can surpass 50% (1). Weed management is just one of the technological components present in any crop technology. Given the biological particularities, wheat crop is mainly weeded with dicotyledonous species. The objective of this paper is the comparative evaluation of the classic method for determ...

Using of photogrammetric methods on quarries of dimension stone for determining cracks parameters and stone block modeling is actual problem. The methodology of applying the modern digital cameras (SLR-type) and terrestrial laser scanning for surveying of mining objects (dimension stone blocks), reception of the information on a camp of rock mass, recognition of cracks in rock massif with following definition of their geometrical parameters, quality control of dimension stone blocks on quarry are considered. The m...

The paper presents a method for authenticating images that were shot using a mobile phone. Thanks to the newest advances in integrated cameras, smartphones represent one of the most popular ways to take a photograph. A picture could be critical evidence in a trial and, with the abundance of free editing software, a forgery is easy to achieve. A method to secure and test photographs for authenticity was developed, implemented as a mobile application, tested and detailed in this paper. The watermarking algorithm is ...
