Abstract
The Digital Image processing deals with the process in which the given image is processed using the techniques such as Image Acquisition, Preprocessing, and Segmentation and so on. These elements of image processing are dealt in order to be in pace with the new developments in image-processing hardware and software. Firstly, in the processing flow the Image Acquisition plays a prominent role. In this process acquiring of the images is done in order to process it. After absorbing the image, it is preprocessed. I.e. the image is Enhanced, Restored and then Compressed. While Enhancing the image or during image enhancement, several techniques are adopted such as gray- scale mappings for image negatives, contrast stretching, gray-level slicing and so on.
After enhancing the required image, it is restored whose ultimate goal is to improve an image or to reconstruct an image that has been degraded by using some priori knowledge of the degradation phenomenon. Then comes the turn of Compression in which the amount of data required to represent a digital image is compressed. Image compression plays a crucial role in many important and diverse applications, including telex video conferencing, remote sensing, FAX etc, In the next process, which is the Segmentation process, the image is divided into several parts or segments.
