Hi , I have images which i need to process further for image rectification.. These images are from newspaper camera shots as given in the figure 70.jpg. To proceed further I needed to detect only the image and not the texts. So i rotated the image -90 degrees and applied contour propagation . BUt i got a result as shown in figure 1.jpg. I could not obtain the proper boundary line which is hampering my work..
I need to detect only image and the four corner coordinates of the image to proceed further. Please provide me information on what steps to take ?
Thanking you
