in this study based on image analysis, an ore grade estimation model was developed. the study was performed at a limestone mine in central iran. the samples were collected from different parts of the mine and crushed in size from 2.58 cm down to 15 cm. the images of the samples were taken in appropriate environment and processed. a total of 76 features were extracted from the identified rock sa...

normal 0 false false false en-us x-none ar-sa digital breast tomosynthesis (dbt) is a technology that creates three dimensional (3d) images of breast tissue. tomosynthesis mammography detects lesions that are not detectable with other imaging systems. if image reconstruction time is in the order of seconds, we can use tomosynthesis systems to perform tomosynthesis-guided interventional procedur...

nowadays, the use of intelligent control systems to reduce human error is one of the most popularresearch fields. design and implementation of such controllers requires to actual knowledge of theenvironment conditions. traffic lights as one of the inputs of intelligent control systems are significant.usually the traffic lights have the various physical structure. also, generally in image proces...

abstract currently in iran, some manual methods are used for measuring spray droplet size which is very laborious and time consuming. in this paper, a software is presented based on image processing techniques, which is suitable for small object detection purpose that can be used in blob analysis of sprayer calibration and other similar applications. the algorithms have been implemented and ada...

introduction: tracking temporal changes of temperature during laser skin treatment plays an important role in improving the process of laser skin treatment itself. there are a number of methods to analyze temperature’s temporal dependency during laser skin treatment; some of those methods depend on imaging the skin with thermal cameras. however, the use of thermal cameras exhibits specific prob...

the range imaging based on conventional pulse compression technique requires lfm signal that sampled by nyquist rate. in order to high resolution increased in range in pulse compression, so the lfm bandwidth has to increase. consequently this procedure dictated limitations on adc sampling. the stretch processing is one of techniques decreasing nyquist rate in radars. in this method the nature o...

using image processing and artificial intelligence systems in agriculture and food industry is increasing daily. the purpose of this research is to study the feasibility of using image processing technique in predicting process of moisture content changes on green tea sheets during the drying using predictive artificial intelligence systems such as: artificial neural networks and adaptive neuro...
