Intravascular Ultrasound (IVUS) provides detailed measurements of the arterial wall. However, during its acquisition, the contraction of the cardiac muscle provokes a relative motion of the transducer with respect to the artery. Consequently, the acquired images are disordered in space. Therefore, to enhance visualization of the coronary artery, volumes of IVUS images of each cardiac phase are needed,...
The present work investigates the qualitative and quantitative effects of the convolution of a Gaussian function with an image. Besides the evaluation of the commonly called "Gaussian-blur" in the filtering of images, this work also investigates a methodology of segmentation using Gaussian blurring. Noise is inherent to the physical process of acquisition. Therefore, to know the effects...
