Image segmentation based on water flow analogy
… objects with complex shapes, like segmenting vessels in iridology and detecting roads in remote sensing, is of practical significance in image analysis. Region growing and snakes are the main methods used in the field, but the former cannot yield an exact result whilst the latter has …

Image Processing Algorithms for Diagnostic Analysis of Microcirculation
… assessment of tissue perfusion and oxygenation. Detection and assessment of the microvasculature using videomicroscopy from the oral mucosa provides a metric on the density of blood vessels in each single frame. Information pertaining to the density of these microvessels within a field of view …

Coherent flow power Doppler imaging
<p>Ultrasonic flow detection is a widely used technique to detect vessel, measure blood flow velocities, and monitor perfusion. Conventional techniques include color Doppler imaging and power Doppler (PD) imaging. These methods depend on either the measurement of phase change or the detection of …
