I am having an Ultrasonic C-Scan gray scale image of a steel billet. I need to find the area of a feature in it by using intensity difference or texture difference or pattern recognition or any other suitable method. The main problem is that the boundries of feature are not demarkated clearly and intensity variation is very less compared to the surrounding area. Will be thankful if anybody is able to give some clues

Other than how to upload an image about all I can say is that you can use image processing. You might also see my Image Segmentation Tutorial if you're a novice at image processing.

I'd probably start with an edge detector and look at the direction of the gradients.
