Window of Visibility in the Display and Capture Process

In normal conditions, the Critical Flicker Frequency is usually 60Hz. But in some special conditions, such as low spatial frequency and high contrast between frames, these special conditions have high probability to occur in some TPVMbased applications. So it’s extremely important to verify if a visual signal with a combination of temporal and spatial frequency can be recognize by human eyes. Based on the research in the last paper ’ ’Window of Visibility’ inspired security lighting system’, this paper introduces the measuring method of WoV of humaneyes. In this paper we will measure critical flicker frequency in low spatial frequency and high contrast conditions, and we can witness a different conclusion from the normal conditions

Review on Movie Piracy Reduction using Infrared Transmitter Screen, Steganography Technique and GSM based Alert System

Cinema is a major entertainment for people in today’s life. To entertain people, a lot of investment is put on cinemas by the film makers. Their effort is being destroyed by few people by pirating the cinema content. They do it by capturing the video in mobile camera and upload it to websites or sell it to people and this goes on. In this study, a technical method is used in order to avoid false recording of video in theaters. An invisible light is projected from the screen to the whole audience that falls on the camera lens which is sensitive to infra-red light rays which alters the capturing functions of the camera. A technical method is developed for anti-piracy system for film industries using steganography technique in MATLAB and to design an IR based screen to disable mobile recording and also a GSM based immediate alert is sent to concerned authority to alert about piracy position using GPS
