This article presents PAPRICA-3, a VLSI-oriented architecture for real-time processing of images and its implementation on HACRE, a high-speed, cascadable, 32-processors VLSI slice. The architecture is based on an array of programmable processing elements with the instruction set tailored to image processing, mathematical morphology, and neural networks emulation. Dedicated hardware features al...

Image segmentation is a fundamental step in many of image processing applications. In most cases the image’s pixels are clustered only based on the pixels’ intensity or color information and neither spatial nor neighborhood information of pixels is used in the clustering process. Considering the importance of including spatial information of pixels which improves the quality of image segmentati...

urban spaces are like a dramatic stage, in which buildings and street’s facades are the actors. while people are passing through streets, they will communicate the information with the environment, as well as, explore and study the spaces. people transfer the greatest number of information from the urban space and the surrounding environment through their visual senses. hiking determines one of...

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...
