1.5.3. Surveillance- Objects can be recognized and tracked for various video surveillance systems. Object recognition is required so that the suspected person or vehicle, for example be tracked. 1.5.4. Robotic- The research of autonomous robots is one of the most important issues in recent years.
The masked object acts like a screen in which the background is projected using video camera. The format of the video should be digital for easy processing. COMPUTER: Powerful computers synthesize graphics and superimpose on real world image on augmented outputs. Computer reckons perspective to simulate the reality and modify the captured image into the image that will be projected on the clock. This technique is image based rendering.
AR technology then contributes the 3D graphics as they would appear from the viewpoint of the camera, superimposing the computer-generated images over a user’s view of the real world. In Virtual Reality, the computer uses similar sensors and math. However, rather than locating a real camera within a physical environment, the position of the user’s eyes are located within the simulated environment. If the user’s head turns, the graphics react accordingly.
MOTION CAPTURE IN 3D ANIMATION Capturing the motion is the process of recording motion of objects or people. This capturing of motion is widely used in military, entertainment world, medical applications, and usually for validation of computer vision. In creating films and developing video games, it termed to as recording actions of actors or human actors, and using that information to animate digital characters in 3D animation. When it makes the inclusion of face and fingers or captures the expressions, it is known as performance capture. In mostly fields, capturing the motion is sometimes called motion tracking, but in making movies and games, motion tracking called as match moving.
The choice of attributes and the way they will be modified are specific to a given task. Enhancement is pre processing step in some computer vision applications to ease the vision task, for example to enhance the edges of an object to facilitate guidance of robotic gripper. Enhancement is also used as pre processing step in applications where human viewing of an image is required before further processing. Image enhancement is used for post processing generate a desirable
A robot must have a vision system to capture the images or videos in the vicinity. Then they can be sent to the microprocessor for processing and some information can be extracted out of them. The eye for a Robot is its sensors to understand the circumstances. There are several types of sensors like IR proximity sensor or sharp IR which can be used depends on their requirements, instead of those, Cameras are now being widely used due
Interactive eye-tracking systems normally respond to the site of the user’s gaze spot. Such systems are divided into two application sub-types: selective and gaze-contingent. Selective applications use the user’s gaze as a substitute mode of input often associated with a pointing device. Gaze-contingent applications involve techniques that let a computer screen to alter in action in accordance to where the user is looking at. There are two main approaches for gaze-contingent applications, viz.
When I draw, I have a tunnel vision of 3D optimality. It 's another universe in my mind; another universe as if I 'm in slow motion. Drawing is much more than just doodling on a sheet of paper. It is a type of visual reasoning, a method for displaying feelings. While drawing I take in the frame, shape, and definition mentally.
1. Introduction Today the tradition in 3D computer graphics, 3D modelling is the process of developing a mathematical representation of any three-dimensional surface of an object (either inanimate or living) via specialized software. The product is called a 3D model. It can be displayed as a two- dimensional image through a process called 3D rendering or used in a computer simulation of physical phenomena. Models may be created automatically or manually.
This process is done when our vision is changed by an image plane consisting of pixels. Out of several pixels any one pixel will be hit by the light particles emanated. This process is continued until all the pixel are regulated, producing a computer generated image. In short, this technique makes it possible to detect how light is carried in nature on computer. B. Backward Ray Tracing Backward ray tracing, also known as eye ray tracing, was introduced to make ray tracing more efficient.
