Purpose. The purpose of this article is to develop a preprocessing method for digital multispectral remote sensing images obtained through optical and infrared means in the electromagnetic spectrum. aims ensure invariance with respect positional formation conditions that determine spatial radiometric resolution. By implementing homomorphic filtering method, we can significantly increase informa...
In this lab, we will cover a useful image processing technique called halftoning, which is the process of converting a gray scale image into a binary image. The process of halftoning is required in many present day electronic applications such as facsimile (FAX), electronic scanning and copying, and laser printing. This lab will cover the halftoning techniques known as ordered dithering and err...
Background and purpose: Dual-energy mammography is a technique which is used to enhance the accuracy of breast cancer diagnosis especially in dense breasts. This study was conducted based on the simultaneous use of two contrast agents for automatic separation and also to evaluate their accuracy using dual-energy digital mammography. Materials and methods: A breast phantom was designed and b...
