Leptomeningeal enhancement in computed tomography of feline brains
(Univ Federal Rural Pernambuco, 2011-12-01)
Contrast enhancement enables the verification of several pathological conditions that lead to vascular changes and/or breakdown of the blood-brain barrier. Examples of diseases that cause these disorders are: neoplastic ...
An Adaptive Beamformer Algorithm-Based BMEVA Method for Enhanced Radar Imaging
(Revista Computación y Sistemas; Vol. 15 No. 2, 2011-12-13)
Abstract. In this paper, an adaptive beamformer algorithm LMS is presented and showed to improve the Bayesian Maximum Entropy–Variational Analysis (BMEVA) performance for high resolution radar imaging and denoising. A ...
Effect of digitization parameters on periapical radiographic image quality with regard to anatomic landmarks
(2011)
The aim of this study was to evaluate the influence of digitization parameters on periapical radiographic image quality, with regard to anatomic landmarks. Digitized images (n = 160) were obtained using a flatbed scanner ...
Evaluation of the combined assessment of two digital enhancement filters in periapical radiographs obtained with different projection angles in the detection of simulated dental root fractures
(2022-04-01)
Objective: To evaluate the diagnostic efficacy of the combined assessment of the original radiographic image with the Invert or Emboss digital enhancement filters in periapical radiographs obtained with different horizontal ...
Learning how to extract rotation-invariant and scale-invariant features from texture images
(Scopus, 2008)
Learning how to extract texture features from noncontrolled environments characterized by distorted images is a still-open task. By using a new rotation-invariant and scale-invariant image descriptor based on steerable ...
Wavelets based Algorithm for the Evaluation of Enhanced Liver Areas
(Spie - Int Soc Optical Engineering, 2014-01-01)
Hepatocellular carcinoma (HCC) is a primary tumor of the liver. After local therapies, the tumor evaluation is based on the mRECIST criteria, which involves the measurement of the maximum diameter of the viable lesion. ...
