In this paper, we present an integrated model to find the optimum size of blast block that uses (i) a multi-criteria decision-making method to specify the applicable size of the mineable block; (ii) a linear programming method for the selection of the blasted areas to be excavated and in deciding the quantity of ores and wastes to be mined from each one of the selected blocks. These two methods...

Image compression is dissimilar than compressing other unprocessed binary data. Obviously, general purpose compression techniques deliberated for raw binary data can be used to compress images, but the result is not the finest one, because of the variations in statistical property of image. Statistical properties of image must be completely exploit by encoders to obtained efficient image compre...

UAV-DAP (unmanned aerial vehicle-digital photogrammetry) has become one of the most widely used geomatics techniques in last decade due to its low cost and capacity generate high-density point clouds, thus demonstrating great potential for delivering high-precision products with a spatial resolution centimetres. The questions is, how should it be applied obtain best results? This research explo...

This paper presents a new semi-fragile algorithm for image tamper detection and recovery, which is based on region attention and two-sided circular block dependency. This method categorizes the image blocks into three categories according to their texture. In this method, less information is extracted from areas with the smooth texture, and more information is extracted from areas with the roug...

This paper describes a binary intage representation schente, called Image Block Representation and presents new algorithms for a number of basic binary image processing and analysis operations, which are rapidly intplemented on block-represented binary images. The main purpose of the hnage Block Representation is to provide an efficient binary image representation that pemtits the execution of ...
