With a view of accomplishing the needs for further analysis on image, Image pre-processing methods are applied on an image for its betterment. Image enhancement is a pivotal part in digital image techniques. The main objective behind image enhancement is to apply an algorithm to original image, so that the resultant image is well suited for a specific task. Digital image enhancement is apt in providing diverse methods for better visualization of image for purpose of object detection and recognition by the machine. Enhancement techniques help us to view the image more efficiently by integrating color and intensity in it. This paper provides detail analysis of different basic enhancement techniques like Min-Max Filter, Gaussian filter, Invert filter, Histogram equalization and Contrast stretching for enrichment of image using ERDAS software. After the analysis an enhanced image is achieved using histogram equalization due to the dynamic range of pixels can grow best for better visualization of an image for better analysis.
