A contour extraction algorithm based on wavelet transform and dynamic contour compensation

, 2016
Contour extraction process is often disturbed by complex backgrounds or foregrounds in the machine vision system. A new contour extraction algorithm is proposed based on wavelet transform and dynamic contour compensation.

Evaluation of Ocular Pulse Amplitude by dynamic contour tonometry in patients with pseudoexfoliation syndrome

, 2009
İntraoküler basıncın sabit bir değeri yoktur. İntraoküler basınç değeri sistol sırasında en yüksek iken diastol sırasında en düşüktür. Bu çalışmanın amacı psödoeksfoliyasyon sendromlu hastalarda «ocular pulse amplitude» değerinin «pascal dynamic contour ...

Dynamic contour tonometry to measure ocular pulse amplitude in patients with suspected giant cell arteritis

, 2017
Dynamic contour tonometry (DCT) provides a painless and quick measurement of ocular pulse amplitude (OPA), which can reflect; ocular perfusion. Primary aim: to delineate the role of DCT in giant cell arteritis (GCA) suspects undergoing temporal artery ...

Intraocular pressure measurements using dynamic contour tonometry after laser in situ keratomileusis.

, 2003
PURPOSE Thinning of the corneal stroma by laser in situ keratomileusis (LASIK) results in inaccurate low intraocular pressure (IOP) readings by Goldmann applanation tonometry (GAT). Dynamic contour tonometry (DCT) is a novel measuring technique, designed
