Abstract: We present a novel approach to change detection between two brain MRI scans (reference and target.) The proposed method uses a single modality to find subtle changes; and does not require prior knowledge (learning) of the type of changes to be sought. The method is based on the computation of a local kernel from the reference image, which measures the likeness of a pixel to its surroundings. This kernel is then used as a feature and compared against analogous features from the target image. This comparison is … Show more

“…The Seo and Milanfar method 4 obtained an average value of 0.879 for SI. As an overall measure of performance, they were able to achieve sensitivity ¼ 0.877, specificity ¼ 0.998, and similarity index ðSIÞ ¼ 0.879.…”

“…For a recent survey, see [83]. Actually, change detection is of significant interest in an increasing number of applications, such as video-surveillance (e.g., in airports, museums, shops, etc), medical diagnosis [18,81,45,88,90], cell biology imaging [78,19] and remote sensing [23,54]. The challenge lies in distinguishing between meaningful changes related to unusual scene events and changes corresponding to camera motion, camera noise or atmospheric/lighting conditions.…”
