Digital Image Processing Using ENVI
Details
INTRODUCTION
Image processing is a method to perform some operations on an image, in order to get an enhanced image or to extract some useful information from it. It is a type of signal processing in which input is an image and output may be image or characteristics/features associated with that image. Recently, image processing is among rapidly growing technologies. It forms core research area within engineering and computer science disciplines too. The participants will be taken through fundamental definitions such as image, digital image, and digital image processing. Different sources of digital images, image processing to computer vision and image acquisition and different types of image sensors shall be covered.
