JAYARAJ ANNAPACKIAM CSI COLLEGE OF ENGINEERING NAZARETH DEPARTMENT OF ECE - IV PAPER ON OPTICAL CAMOUFLAGE (Application to IMAGE PROCESSING) BY, J.IMMANUEL V.JEFRINS E MAIL-ID : firstname.lastname@example.org Jefona47@gmail.com ABSTRACT: The abstract of this paper is the working principle of a Harry Potter-like invisibility cloak. In order to make the cloak invisible, Light from all directions travel through the object, rather than hitting it. Because of not being able to interact with light, the hidden object is therefore made invisible. Optical Camouflage: Active camouflage provides concealment in two important ways: firstly, it makes the camouflaged object appear not merely similar to its surroundings, but effectively invisible through the
Even though they are able to see light and movement, they are not able to see color. This is what they are able to see with their eyes, however, some are also able to with their mind’s eye. Utilizing other senses and technology such as cortical implants, the blind population is able to create images in their mind’s eye. II. The main causes of blindness and visual impairments.
Light reflects off of the person, place, or thing you are trying to create a photo of. The light being reflected will reflect in many different angles. A film is placed where the image will be projected to. The lens then focuses these rays of light behind the focal point and forms an image. Science is used in the development of the film or special paper so that the pictures are able to develop fully and properly.
Image enhancement is the mechanism to process the input image to make it more appropriate and clearly visible for the required application. Image enhancement improves the information content of the image and alters the visual impact of the image on the observer. The objective of image enhancement is to modify attributes of an image to make it more suitable for a specific task. In the image enhancement process, one or more attributes of the image are modified and processed. The choice of attributes and the way they will be modified are specific to a given task.
CCTV (Closed-circuit television): Use of video cameras to observe an area. In this document we will mainly focus on Video Surveillance. CCTV cameras are used to observe an area. The video is then used to identify a specific scene such as human activities, vehicular traffic and further more. Surveillance systems are mostly important in the field of security.
Laser and green fluorescence excite the specimen and it goes under the mirrors scanning in the device. The emitted light by the laser passes a dichroic mirror and it focused to the pinhole (figure 4). Then it is detected by the microscope's camera or photodetector. It should be noted that the sample is being scanned point by point and to get a complete image the computer must build up the image of one pixel at a time. The mirrors in a confocal microscope are controlled by a computer that can store and analyze the produced data.
This 3D image of the thorax can be studied, stored, acquired and shown as an informational structure bases on imaging. Using this principle the bronchial tree (and the surrounding structures if needed) can be identified, and removed from the larger image and studied in 3D digital space. Most of the companies now offer virtual bronchoscopy software with their scanners (Ferguson & McLennan,
3.2. What is ALPR? Automatic license plate recognition (ALPR) is a mass surveillance method that uses optical character recognition (OCR) to automatically identify the license number plate in an image or video. By providing the OCR with the correct search criteria you need to train it. To train the OCR means to get enough positive and negative images of the object you want to identify.
Abstract-: Image Stitching or mosaicing is an important aspect of research in the field of computer vision. It involves various techniques of joining images together to form a mosaic of high resolution. Stitching images generally require complete overlap in order to generate high resolution panoramas. As these panoramas become increasingly popular, there arises a need for the software to create mosaics. These mosaics are used for variety of applications like in digital maps and satellite photos.
Virtual reality is the computer-simulated three-dimensional virtual images, gives user an experience like in a real world , the scene will change simultaneous when moving the head and the body, by using the controller or eye point, user can have interaction with the virtual world. Virtual reality system should contain three basic features, immersion-interaction-imagination . Immersion means the simulated environment is so vivid just the same as reality, user can hardly distinguish or even cannot differentiate virtual reality and reality, and all the control in this environment is just as natural as in the real world. Interaction means user is able to interact everything in the virtual environment, and the virtual environment can give feedback based on that, imagination simply means it can simulate all the possible and impossible scenes, such as see through a human body to observe the internal organs and blood vessel or have an adventure to the Mars which is beyond what human can achieve. Those features indicate that in the future human will hold the leading position in the VR system.
