It is a technique to modify or interpret existing pictures, such as photographs. Two principal applications of image processing are:
1. Improving picture quality
2. Machine perception of visual information as used in robotics
2. Machine perception of visual information as used in robotics
Working of image processing: To apply image-processing methods, we first digitize a photograph or other picture into an image file. Then digital methods can be applied to rearrange picture parts, to enhance color separations, or to improve the quality of shading. An example of the application of image-processing methods is to enhance the quality of a picture. These techniques are used extensively in commercial art applications that involve the retouching and rearranging of sections of photographs and other artwork. Similar methods are used to analyze satellite photos of the earth and photos of galaxies.
