After having analyzed the different causes of macroscopic displacements of photocarriers in LiNbO 3, the corresponding photoinduced changes of refractive index are computed for the short-circuited and open circuited crystal. It is shown in the second case that total or selective erasure can be performed, using a coherent substraction technique. REVUE DE PHYSIQUE APPLIQUÉE TOME 10, NOVEMBRE 1975...

A 22-year-old female patient presented to the Emergency Department of a tertiary care hospital with symptoms of headache and nausea. She has been on a regular follow-up for the preceding three and a half years after being diagnosed as systemic lupus erythematosus (SLE). She had been treated earlier for SLE nephritis in the same institution, and had two relapses of nephrotic syndrome in the last...

We report the case of a 13 yr old, asymptomatic girl with agenesis of the right pulmonary artery. In the context of a tuberculosis survey in her school, an X-ray examination disclosed a decreased volume of the right lung. Ventilation and perfusion scans and digital substraction angiography established the diagnosis.

Prajurit TNI khususnya AD di tuntut untuk memiliki kemampuan dan kehandalan dalam menembak. Dalam menunjang tersebut, maka setiap prajurit akan melaksanakan latihan menembak 3 bulan sekali. menghitung skor tembak, saat ini masih dilakukan secara manual yakni ada personil yang bertugas mengamati menilai dari tembak. Hal merupakan perkerjaan beresiko tinggi berbahaya salain itu juga sangat melela...

In this paper, we present a method for background modeling using only keypoints, and detection of foreground moving pedestrians using background keypoints substraction followed by adaBoost classification of foreground keypoints. A first experimental evaluation shows very promising detection performances in real-time.

Primary and secondary gastrointestinal tumors have been identified using sheep immunoglobulin G antibody to carcinoembryonic antigen radiolabeled with 131I. 99mTc-pertechnetate and 99mTc-human serum albumin were used to identify tissue spaces and blood pool and to facilitate external substraction imaging. In 13 patients with tumors, 4 of 5 primary sites and 8 of 11 secondary sites were successf...

The paper presents a new [pseudo-] Logarithmic Model for Image Processing (LIP), which allows the computation of gray-level addition, substraction and multiplication with scalars within a fixed graylevel range [0;D] without the use of clipping. The implementation of Laplacian edge detection techniques under the proposed model yields superior performance in biomedical applications as compared wi...

In order to satisfy the moving object diction and tracking’s real-time and self-learning performance, the method which combines background substraction and threshold image segmentation on HSV space is presented in this paper. Detecting the real-time image and getting the threshold of HS space. Next, the moving object’s area is got by the thresholds segment. Third, getting the center and realize...
