detecting hyperbolic regions in an image matlab

I have grey scale images as shown (it is scanned profile of an actual construction bridge). I would like to identify or detect hyperbolic variations or regions in it (and preferably separate them in the form of boxes as shown in another image). I have tried canny edge detector, texture segmentation and other methods, but they are not as reliable ..i.e., they don't have high degree of accuracy. The problems associated with this are: a) Sometimes the hyperbolic variations are too close..so I have to stretch the image and adjust contrast. b) Sometimes the region contrast is too light or heavily distorted.. but I still wanna detect them.. Please suggest a suitable method or code to identify it.. I have attached some sample images..
another sample - https://www.dropbox.com/s/mgskgb62cz5mrhv/FILE____022%20P_1.png?dl=0&preview=FILE____022+P_1.png
Thank you very much for your suggestions..
