A method of video flame detection based on multi-feature fusion is presented in this paper. Physical characteristics of flame, including color clues, flame movement and flame flicker are incorporated into the scheme to detect fires in color video frames. Firstly, mean filtering was used to smooth the video frames and a flame color filtering algorithm was adopted to extract flame candidate regio...

THE finest movements of surgery are made with the fingers and thumb, not with the wrist and hand as a whole. In the usual method of suturing, the needle is grasped by the needle-holder which is held more or less in the palm of the hand. The fine, sharp needles of ophthalmic surgery, such as those made by Grieshaber, inevitably become dulled as they are grasped by the metal blades of the needle-...

Introduction: Bite wing radiographs are indicated in children with closed posterior contacts. Given the fact that nowadays bitewing radiographs are taken using both paper loop and film holder, the aim of this study is the evaluation of acceptance and diagnostic quality of two methods. Materials and Methods: This study is a sort of diagnostic accuracy test that was performed on 20 6-8 year old ...

We present a study of the flame-embedding concept, introduced in [1] as an efficient approach for large-eddy simulation of turbulent combustion at high Reynolds and Damköhler numbers. In flame embedding, the combustion zone is modeled as an unsteady flame modified by the local tangential strain rate, with the latter extracted every time step from the flow field simulations. The flame structure ...
