OBJECTIVE Early hematoma expansion is a known cause of morbidity and mortality in patients with intracerebral hemorrhage (ICH). The goal of this study was to identify clinical predictors of ICH growth in the acute stage. MATERIALS AND METHODS We studied 201 patients with acute (<6 h) deep ganglionic ICH. Patients underwent CT scan at baseline and hematoma(More)
In this correspondence, a parallel algorithm, in order to extract parametric curves from a two-dimensional (2-D) image space, is proposed. It is based on the Hough transform (HT) and uses the content addressable memory (CAM) as the main processor. A set of simulated results for circular shape extraction are presented in order to demonstrate its merit.(More)
Mathematical morphology is a promising computer paradigm based on set theory and has many applications in image processing. Although some architectures have been proposed, there are as yet no compact, practical computers that can handle a variety of morphological operations with large, complex structuring elements at video rates. This has prevented the(More)
This paper proposes a new architecture for a single-chip MPEG-2 video encoder with scalability for HDTV and demonstrates its exibility and usefulness. The architecture based on three-layer cooperation provides exible data-transfer that improves the encoder from the standpoints of versatility, scalability, and video quality. The LSI was successfully(More)
