Human body segmentation is a critical module in video-based activity recognition (AR) because it defines the image area necessary and sufficient for the follow-up modules like feature extraction. Existing methods often involve modeling of the human body and/or the background, which normally requires extensive amount of training data and cannot efficiently handle changes over time. Recently, active...
In this paper, we present a novel active contour (AC) model for medical image segmentation that is based on a convex combination of two energy functionals to both minimize the inhomogeneity within an object and maximize the distance between the object and the background. This combination is necessary because objects in medical images, e.g., bones, are usually highly inhomogeneous while distinct organs...
Ubiquitous Life Care (u-Life care) nowadays becomes more attractive to computer science researchers due to a demand on a high quality and low cost of care services at anytime and anywhere. Many works exploit sensor networks to monitor patient's health status, movements, and real-time daily life activities to provide care services to them. Context information with real-time daily life activities can...
Conventional vessel enhancement approaches used in literature are Hessian-based filters, which are sensitive to noise and sometimes give discontinued vessels due to junction suppression. In this paper, we propose a new approach incorporating the use of linear directional features of vessels to get more precise estimates of the Hessian eigenvalues in noisy environment. The directional features are...
