5. 3. Elliptical Adaptive Structuring Elements for Mathematical Morphology

   Author : Anders Landström; Jesús Angulo; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

   Abstract : As technological advances drives the evolution of sensors as well as the systems using them, processing and analysis of multi-dimensional signals such as images becomes more and more common in a wide range of applications ranging from consumer products to automated systems in process industry. Image processing is often needed to enhance or suppress features in the acquired data, enabling better analysis of the signals and thereby better use of the system in question. READ MORE

   Abstract : Renal cell carcinoma (RCC) is the cancer of the kidneys; about 1100 patients with RCC are diagnosed in Sweden each year. RCC can be classified into several subtypes, clear cell renal cell carcinoma (ccRCC) is most common accounting to about 70% of all RCCs, and also the most lethal; papillary renal cell carcinoma (pRCC) accounts to about 10%‐15%, while chromophobe renal cell carcinoma (chRCC) accounts to about 5% of all RCCs.
