Digital Image Processing in Hindi Urdu

So, you find that digital image processing techniques is motivated by 2 major applications. The first application is improvement of pictorial information for human perception. So, this means that whatever image you get, we want to enhance the quality of the image so that the image will have a better look and it will be much better when you look at the image. The second important application of the digital image processing techniques is for autonomous machine applications. This has various applications in industries, particularly for quality control in assembly automation and many such applications. We will look at them one after another. And of course, they use a third application which is efficient storage and transmission. Say for example, if we want to store an image on a computer, then this image will need certain amount of disk space. Now, we will look at whether it is possible to process the image using certain image properties so that the disk space required for storing the image will be less. Not only that, we can also have applications where we want to, we want to transmit the image or the video signal over a transmission media and in that case, if the bandwidth of the transmission medium is very low, we will see that how to process the image or the video so that the image or the video can be transmitted over low bandwidth communication channels.
