Two-dimensional and three-dimensional sonography of conjoined twins.
2002
Purpose The aim of this study was to evaluate and compare the diagnostic capabilities of 2-dimensional (2D) and 3-dimensional (3D) sonography for the study of conjoined twins. Methods Four pregnant women with an initial 2D sonographic diagnosis of conjoined twins were examined with color Doppler sonography, 3D multiplanar sonography, and orthogonal plane imaging and 3D surface rendering. Results All 4 cases of conjoined twins were initially diagnosed with either transvaginal or transabdominal 2D sonography. 3D sonography afforded more realistic views and demonstrated more clearly the linking areas and surface anomalies, but 2D and color Doppler sonography provided more definitive and specif…
Time Unification on Local Binary Patterns Three Orthogonal Planes for Facial Expression Recognition
2019
International audience; Machine learning has known a tremendous growth within the last years, and lately, thanks to that, some computer vision algorithms started to access what is difficult or even impossible to perceive by the human eye. While deep learning based computer vision algorithms have made themselves more and more present in the recent years, more classical feature extraction methods, such as the ones based on Local Binary Patterns (LBP), still present a non negligible interest, especially when dealing with small datasets. Furthermore, this operator has proven to be quite useful for facial emotions and human gestures recognition in general. Micro-Expression (ME) classification is…
Abdominal wall defects: two- versus three-dimensional ultrasonographic diagnosis.
2001
We diagnosed 12 cases of abdominal wall defects. The cases diagnosed occurred in 6 fetuses with omphalocele, 3 with gastroschisis, 2 with prune-belly syndrome, and 1 with pentalogy of Cantrell. Except for 1 case of gastroschisis first diagnosed on the basis of three-dimensional ultrasonography at 14 weeks' gestation, all cases were first detected by two-dimensional transabdominal ultrasonography and then reevaluated with three-dimensional ultrasonography using multiplanar and orthogonal plane modes. Although the original diagnosis was accurate on the basis of two-dimensional ultrasonography in 11 of 12 cases, additional information was obtained by three-dimensional scanning in all cases. Ou…
