Today it is already widely accepted that out of school education exceeds formal education in content and knowledge and that it is not a plus, but a necessity. However, unlike formal education, educators working in informal settings are often volunteers or/and they do those activities on top of their daily jobs. The research questions we pose here are (i) what motivates people to volunteer in K-12...
Even students who are provided with currently best available education in Science, Technology, Engineering, Mathematics and Computer Science (STEM-C) fields are having problems coping with living in the modern world where technological advancements happen on a daily basis, let alone students coming from economically disadvantaged backgrounds. In a world where institutions offering formal education...
It is a great pleasure welcoming all of you to the IEEE International Wireless Communications and Mobile Computing Conference (IEEE IWCMC 2015) in the beautiful Dubrovnik, Croatia! We are indeed delighted that this year's IEEE IWCMC lived up to its goal under the conference theme “Communications for the 21st Century,” and continues its tradition of providing the premier forum for presentation of research...
Switching to digital technology from analog brought many changes, especially in storage of digital X-ray images. In cases of multiple fractures or need for imaging of a large area it is necessary to make more than one X-ray image for the observed part of body. This is often the case with spine, legs and arms. Radiologists use dedicated workstations to view X-ray results and need to manually switch...
Microcalcifications are tiny calcium deposits present in the breast tissue. They are proved to be an important early sign of a process which started to happen and could be a development of a breast cancer. Because of that computer-aided detection systems (CADe) for detection of microcalcifications with low false positive rate can be very useful and helpful for breast cancer prediction. Accurate detection...
It is our great pleasure to welcome you to the 21st International Conference on Systems, Signals and Image Processing, IWSSIP 2014. Welcome to Dubrovnik! Welcome to Croatia!
An automated system that can provide feedback about aesthetic value or quality of headshot photos based on learned rules could be a very useful support in photo searching, sorting and editing. This is a challenging problem as it requires semantic understanding of photos, which is beyond the state-of-the-art in computer vision. In this paper, we present a method built on most important rules or guidelines...
Determining the breast density in mammograms is important both in diagnostic and computer-aided detection applications. Knowing the right breast density and having knowledge of changes in breast density could give a hint of a process which started to happen within a patient. Breast density could be rather easily estimated by dividing mammogram into fibroglandular and fat tissue. Mammograms suffer...
According to the latest Internet usage statistics, more than 4.5 million photos are being uploaded to Flickr every day. An automated system that can provide feedback about aesthetic value or quality based on learned rules could be a very useful support in picture searching, sorting and editing. This is a challenging problem as it requires semantic understanding of images, which is beyond the state-of-the-art...
Determining breast density in mammograms is important both in diagnostic and computer-aided detection applications. Knowing the right breast density and having knowledge of changes in breast density could give a hint of a process which started to happen in a patient. Mammograms are projection images and suffer from problem of overlapping tissue which results in possibility of inaccurate detection...
According to American Cancer Society's most recent studies, breast cancer is the most common cancer among women today and a serious threat worldwide. Mammography, whether screen-film or digital, remains the best method to detect early breast cancer. Mammography imaging relies on the projection of a three-dimensional object onto a two-dimensional image in which lesions can be easily obscured and undetected...
The first step in computer aided detection (CAD) in mammography relies on accurate image segmentation. Testing of CAD algorithms should include comparison with other proposed methods in order to show how a new method compares with ones presented before. Two most popular mammographic databases, which are publicly available, consist of scanned films. This presents a segmentation challenge in order to...
Mammographic image registration is an important step in the analysis of differences between the left and right breast in order to detect bilateral asymmetry, which is an early sign of breast cancer. We have used rigid registration to align left and right mammographic images as a first step for comparing corresponding regions in the left and right breast. Registration performance was tested on a dataset...
Computer aided detection (CAD) in mammography relies on accurate image segmentation. If we consider using CAD on non-digital mammograms, one of the steps which need to be performed is scanning. After scanning, images have to be segmented and this is more complicated than segmentation of digital mammograms. In this paper we propose a method for automatic registration of printed and scanned mammograms...
In this paper we present new approach to the objective image quality evaluation based on discrete wavelet transform (DWT) and particle swarm optimization (PSO). DWT was applied on image difference (difference between original and degraded image) that is decomposed into approximation and detail subbands. DWT coefficients were computed using Coiflet wavelet filter banks. The coefficients were used to...
Mammography is probably the best method for early detection of abnormalities in the breast tissue. Higher breast tissue densities significantly reduce the overall detection sensitivity and can lead to false negative results. In automatic detection algorithms, knowledge about breast density can also be useful for setting an appropriate threshold. It is impossible to produce satisfactory classification...
Segmentation and grouping of image elements is required to proceed with image recognition. Due to the fact that the images are two dimensional (2D) representations of the real three dimensional (3D) scenes, the information of the third dimension, like geometrical relations between the objects that are important for reasonable segmentation and grouping, are lost in 2D image representations. Computer...
This paper will explore current state of the art in bringing radiological images to modern mobile phones. Short history is given, with focus on PDA devices, and current software development process is described with focus on smartphone mobile web browsers.
The first scenarios of interworking between WLAN and 3GPP networks, which were predicted from 3GPP standards, are already in usage today. Both technologies, WLAN and 3GPP are developing to enable more bandwidth and faster data rates for the end users and represents in some areas complementary solutions. The cooperation between those two networks would enable additional radio capacity for 3GPP networks...
There has been increased interest in developing location services for wireless communications systems over the last several years. Mobile network operators are continuously investigating new innovative services that allow them to increase the profit. In the days to come, location based service or LBS will be benefiting both the consumers and network operators. While the consumers can expect greater...
