The novel ENEA-INMRI Image Analyzer system has been tested in semi-automated mode for a computer-assisted alpha track counting of electro-chemically etched (ECE) and chemically etched CR-39 Solid State Nuclear Track Detector (SSNTD) chips. A track recognition program based on the Java-Image J processing software was developed. Experimental tests have been carried out to maximize the Field of Vi...

Introduction Advanced computer assisted image evaluation of breast cancer requires separation of breast tissues from other tissues and regions of the body, such as chest muscle, lungs, heart and ribs, that may confound image analysis. In addition, MR breast images generally have inhomogeneous signal intensities, together with partial volume effects at tissue or skin interfaces, that can comprom...

Introduction: Diabetic retinopathy (DR) is the single largest cause of sight loss and blindness in the working age population of Western countries; it is the most common cause of blindness in adults between 20 and 60 years of age. Early diagnosis of DR is critical for preventing vision loss so early detection of microaneurysms (MAs) as the first signs of DR is important. This paper addresses th...

background: breast cancer is one of the most important diseases in females. malaysian women have not excluded. according to the malaysian oncology society [1], about 4% of women (who are 40 years old and above) have involved by breast cancer. masses and microcalcifications are two important signs for breast cancer diagnosis on mammography. according to our estimation, radiologists could diagnos...

We propose an extension to the pixel pipeline of current programmable rasterization hardware to include the possibility to freely locate the rasterization position of fragments and pixels. The corresponding new primitive name is Vragment (variable fragment). We show how this new functionality could lead to new and wider classes of algorithms in computer graphics, especially in image processing,...

This study explored the effectiveness of the two computer-assisted modes: cooperative and individual on improving Iranian high school students’ reading comprehension. It was also concerned with investigating the effectiveness of the two computer-assisted modes on the participants’ foreign language learning anxiety (FLLA). The sample of the study consisted of two intact groups, each containing 2...
