Real-time three-dimensional ultrasound enables new intracardiac surgical procedures, but
the distorted appearance of instruments in ultrasound poses a challenge to surgeons. This …

This paper proposes a novel closed-form solution to complete line-segment extraction.
Given a voting angle in image space, the voting distribution is analyzed and two functional …

Image-guided interventions have become the standard of care for needle-based
procedures. The success of the image-guided procedures depends on the ability to …

We present improvements of an adaptative Hough transform algorithm applied to the search
of a common center of circular or partially circular components present in an image. The …

Sea surface currents are of significant importance in various scientific and maritime
applications. There are several measurement techniques available to study surface currents …

3D Ultrasound-guided needle insertion has recently received much attention in minimally
invasive percutaneous procedures such as image guided needle steering. In this paper we …

Purpose Sagittally reconstructed 3D (SR 3D) ultrasound imaging shows promise for
improved needle localization for high‐dose‐rate prostate brachytherapy (HDR‐BT); …

Defocus and twofold astigmatism are the key parameters governing the contrast transfer
function (CTF) in transmission electron microscopy (TEM) of weak phase objects. We …

Perfume microcapsules for laundry applications are extensively used in home and
consumer care products. Capsules have to bind into the fabric during washing and survive …

Object recognition is an automated image processing application of great interest in areas
ranging from defect inspection to robot vision. In this regard, the generalized Hough …
