avoiding video recording

1. avoiding privacy in cinema using
IR camera

2. abstract
• In the present period, the issue of theft turned into a significant
issue for survival of Indian film industry. Because of robbery, silver
screen industry endures an enormous measure of money related
misfortune. Albeit, Digital Cinema Initiatives characterizes a
criminological checking framework in their gauges with a specific
end goal to ensure their copyrights. Be that as it may, it is not
adequate to maintain a strategic distance from theft. Since it just
shows when and where was theft done, however not the genuine
area of the camera. The primary test is to decide the area of the
camera in the theatre. In this paper, a Fractional spline wavelet
transformation and Location Tracking Algorithm to decide camera
of the picture has been investigated and introduced. This technique
can be utilized to decide the position of the camera in the theatre.
Trial comes about demonstrate the legitimacy of proposed work.

3. Need to study
• Digital Cinema industry suffers a huge amount of loss
because of the illegal recording of a movie in a theatre
during its release. The loss is inflicted because of the fact
that these recorded illegal copies are floated on the
internet, which in turn is downloaded by viewers and
instead of buying a DVD or going to the theatre to watch it.
People prefer watching the pirated version of the movie.
This type of black marketing not only inflicts loss to the
Producer/Financiers of the movie, but also to the theatre
owner, DVD developer, etc. To deterrence of illegal
recording many entertainment companies use copy
protection technologies. Digital Cinema Initiatives (DCI)
defines a forensic marking system in their standards in
order to protect their copyrights

IR imaging is playing an important role in industry these days. However,
the IR cameras only support low resolution for technical reasons. In this
paper, we propose to use the visible camera as a guidance to super
resolution the IR images. We setup a prototype of the IR-Color multi-
sensor imaging system and construct a dataset including videos collected
from different scenes for further research. Then we present our color
guided algorithm which is suitable for this kind of super resolution
problem. We test our algorithm on our dataset. The experiment results
indicate that our algorithm performs well, and avoids the over-texture
problems that traditional solutions suffer from. In further work, we will
apply our multi-sensor system to more applications in computer vision.

2014)Year: 2014
This paper presents an environment map building method to detect and to
avoid obstacles using a low-cost IR sensor and the turn angle of a servo
motor for autonomous mobile robots. The environment map building
methods widely used by autonomous mobile robots require an expensive
sensor or several sensors, such as camera, laser sensor and so on. With
the method we present, an autonomous robot can draw the environment
map without using the several expensive sensors. We control the mobile
robot through the IR sensor on the servo motor for increasing the obstacle
recognition range. The distance data and the angle of the motor are used
to draw an environment map. The proposed method was verified in a
controlled environment by experiment.

6. Enhancement of method for preventing illegal recording of movies to
enable it to detect cameras with attached infrared-cut filter

Processing (ICASSP)Year: 2012
A previously proposed method for preventing the illegal recording of movies,
which uses a charge-coupled device or a complementary metal oxide
semiconductor device to add noise signals to the recorded content, is
ineffective when the digital camera or camcorder used for the recording is
equipped with an infrared-cut filter. The method has now been enhanced
to make it effective even when an infrared-cut filter is used. Infrared rays
specularly reflected from the filter are detected using an IR camcorder
with a short-wavelength cut filter. Testing using a prototype system
implemented on a 100-inch cinema screen showed that the enhanced
method effectively detects in real time a camera or camcorder equipped
with an infrared-cut filter.

7. Multimodal target detection via integrated GLRT
Steven Kay; Fuat Cogun

The focus of this paper is the multimodal detection and localization of a
ground moving target based on radio frequency (RF) and infrared (IR) data.
The target radiates a low probability of intercept (LPI) RF signal received
by multiple passive RF sensors at scene and is imaged by using a stationary
IR camera concurrently. To obtain the multimodal detector proposed in
this paper, first, the generalized likelihood ratio test (GLRT) is employed to
derive the RF and IR detectors individually. Then, the RF and IR detectors
are integrated optimally to get the integrated GLRT. In order to avoid the
computational complexity associated with the integrated GLRT, a
suboptimal multimodal detector is implemented by applying the random
basis functions (RBF) approach to the IR image sequence to reduce down
the search space for the RF detector. It is shown that the suboptimal
multimodal detector has better localization performance compared to the
RF detector when one of the RF sensors is partially occluded

8. Technique for Estimation of the Position of the Pirate In-Theater Piracy

In the present era, the problem of piracy became a crucial issue for survival of
Indian film industry. Due to piracy, cinema industry suffers a huge amount of
monetary loss. Although, Digital Cinema Initiatives defines a forensic marking
system in their standards in order to protect their copyrights. However, it is not
sufficient to avoid piracy. Because it only shows when and where was piracy done,
but not the actual location of the camera. The main challenge is to determine the
location of the camera in the theater. In this paper, a method to determine tilt
angle of the image has been analyzed and presented. This method can be used to
determine the position of the camera in the theater. The proposed work uses the
projective to transform and zero padding technique for finding the tilt angle of the
image. Experimental results show the validity of proposed work.

9. Existing system
• Privacy protection has been attracting considerable attention in
recent years. Several instances of surveillance video recordings of
famous people in public stores being uploaded to the Internet have
been reported. Such instances of privacy infringement have become
increasingly concerning. A simple solution to this problem is to
obscure the facial features of individuals being recorded in
surveillance camera systems. However, in some cases where
surveillance camera recordings are required, such as criminal
investigations, the solution fails. Therefore, we propose a new
surveillance camera system that balances the requirements of
privacy protection and those of cases in which unobscured images
are required. Further, we present the protocol of the proposed
system and evaluate the security of the system against attacks.

10. Proposed system
• Digital Cinema industry suffers a huge amount of
loss because of the illegal recording of a movie in
a theatre during its release. The loss is inflicted
because of the fact that these recorded illegal
copies are floated on the internet, which in turn
is downloaded by viewers and instead of buying a
DVD or going to the theatre to watch it. IR
camera based method is used to determine the
position of the camera in the theatre. The
proposed work uses the projective to Fractional
Spline wavelet Transform and Location Tracking
Algorithm for finding the location of the camera .
