Foreground-background segmentation in videos is an important low-level task needed for many different applications in computer vision. Therefore, a great variety of different algorithms have been proposed to deal with this problem, however none can deliver satisfactory results in all circumstances. Our approach combines an efficent novel Background Substraction algorithm with a higher order Mar...

CONSEQUENCES IN ARTICULATORY MODELLING Gérard Bailly, Pierre Badin & Anne Vilain Institut de la Communication Parlée INPG & Université Stendhal 46, avenue Félix Viallet, 38031 Grenoble Cedex 1, France Abstract Linear component articulatory models [9, 10, 5] are built using an iterative substraction of linear predictors of the vocal tract geometry. In this paper we consider the contribution of j...

In this paper, an improved method based on Curvelet Transform using different window functions is presented for the speech enhancement. The window function is used for preprocessing of speech signals. In this method, instead of using two-dimensional (2-D) discrete Fourier Transform, Curvelet transform is employed with spectral magnitude subtraction method. General terms Spectral Substraction Me...

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...

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...
