Optical flow is a technique for identifying the density velocity or motion vector (MV) in each pixel for motion estimation of image sequences. Under the real situation, many undesired conditions usually generate noises over the sequences and therefore this situation is corrupts the performance in reliability of optical flow. In order to increase the reliability of the density velocity, this paper...
We propose a method for early fire detection based on the Lucas-Kanade optical flow algorithm that is able to detect fire in real time in a video stream from a monocular camera. The method works both indoors and in open areas. It detects fire at the beginning of the burning process, enabling an earlier response than would be possible with a conventional fire detector. The method performs background...
We propose a new design for all-optical S-R flip-flop using optical technique namely dark-bright soliton conversion control within an optical add-drop filter. In operation, all-optical data input logic ‘0’, ‘1’ is formed by dark soliton (D) and bright soliton (B) pulses, respectively. The conversion behaviour between dark and bright soliton pulses can be obtained and formed the logic pulses by a π/2...
We propose a new design of most important logical circuits using optical devices for all-optical addition/subtraction applications, in which the simultaneous operation of addition/subtraction arithmetic operation can be performed by using the dark-bright soliton conversion control. In operation, all-optical data input for addition/subtraction of binary operation logic ‘0’ and ‘1’ are formed by dark...
