These images were from a numeric display taken from a camera so the numeric characters may not stay in a horizion line if the camera snapshot was slented. I tried using ocr() in matlab and have not able to good performacne on the detction

I'm not sure it's needed but you can easily find the blue stuff on the background and use it's angle to rotate the image with imrotate. Pretty trivial.

Next, you can use ocr() in the Computer Vision Toolbox if you have abinary image of the digits, which you probacly can get through some segmentation method such as thresholding.
