Computer-Vision计算机视觉英文ppt

1、Computer Vision 人人Stereo images acquired by a stereo vision system can be used to reconstruct 3D scene information.Courage RoverRocky 7 Mars rover1）(input device) including imaging equipment and digital equipment. Imaging device is a device which can detect the scene or object by the optical camera

2、or X rays, and get the 2D or 3D digital image of the scene or object.2）(low level) Mainly to deal with the input image. This process uses a large number of image processing techniques and algorithms, such as image filtering, image enhancement, edge detection, texture detection, motion detection, in

3、order to extract the basic features of the scene.3）（middle level） The main task is to restore the depth of the scene, the direction of contact normal , contour and other 2.5 dimensional information of the relevant scene, the method to achieve it include stereo vision、rangefinder.4）（high level） the m

4、ain task has three aspect,one is to reconstruct the complete 3D graph ,the second is to build the 3D description of object ,the third is to recognize and determine the position and orientation of the object.these process is based on the original input image, the basic characteristics of the image.1）

5、(image processing) Image processing is usually the transformation of an image into another image; The computer vision system takes the image as the input signal and generates another form of output signal. Image processing plays a great role in the early stage of machine vision system.2） (computer g

6、raphics) It use geometric primitives (such as lines, circles) to generate the image, which belongs to the image synthesis; computer vision is just to solve the opposite problem, that is to estimate the geometric primitives and other features from the image, which belong to the image analysis. Visual

7、ization and virtual reality are closely related to the two fields. 3） (pattern recognition) It studies classification problem, determine the category of symbols, pictures, objects and other input objects. it researches the common characteristic of a kind of things ,which is different from other thin

8、gs. It generally do not care about the restoration of the three-dimensional world. Pattern recognition method is one of the important bases of computer vision.4） (Artificial Intelligence) it refers to the design of intelligent system and the study of intelligent computing. After the process of image

9、 processing and feature extraction, the computer vision is used to represent the feature of the scene by the method of artificial intelligence. Computer vision is regarded as a branch of artificial intelligence.5） (Arificial Neural Networks) It is an information processing system,which is composed of a large number of simple processing units which are connected with each other by a strong connection to realize the parallel and distributed processing
