Mammographic risk assessment is concerned with the probability of a woman developing breast cancer. Recently, it has been suggested that the density of linear structures is related to risk. For 321 images from the MIAS database, the images were segmented in to dense and non-dense tissue using a method described by Sivaramakrishna, et al. In addition, a measure of line strength was obtained for each...
Mammographic risk assessment is concerned with the probability of a woman developing breast cancer. Recently, it has been suggested that the density of linear structures is related to risk. Two independent sets of mammographic images were annotated according to BIRADS risk classes by expert radiologists. Linear structure information was extracted from each image using the line operator method, and...
Mammographic risk assessment is concerned with the probability of a woman developing breast cancer. Recently, it has been suggested that the density of linear structures is related to risk. For 321 images from the MIAS database, a measure of line strength was obtained for each pixel using the Line Operator method. The proportion of pixels with line strength above a threshold level was calculated for...
This paper presents a smart distribution grid testbed to test or compare designs of integrated information management systems (I2MSs). An I2MS extracts and synthesizes information from a wide range of data sources to detect abnormal system behaviors, identify possible causes, assess the system status, and provide grid operators with response suggestions. The objective of the testbed is to provide...
This work proposes a noise reduction system for use in high noise environments such as motor racing. First, an analysis of the audio data received from the driver reveals that the main noise sources are from the engine, airflow and tyres. These are found to relate to engine speed, road speed and throttle position information that is received in a data stream from the car's on-board computer. A two-stage...
