Take a look at the attached image. it has been processed up till this stage. But its a little difficult and complex algorithm trying to extract the relevant area (number plate region) using the following steps. 1. label connected components 2. Find centroid of each region 2. if centroid of region along x-direction (horizontal direction)are equalto or less than 10 pixels along the x-direction (horizontal direction), MERGE. 3. Boundbox of region larger than threshold T

Any other approach of localizing the number region of the image above would be appreciated.

You can ask regionprops to get the bounding box, though it won't be tilted. You can use propfilt() to filter out blobs not meeting criteria, or do it "manually" like I do in my Image Segmentation Tutorial: http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862&sort=downloads_desc
