1. Given the following image matrix, forward project from the image matrix over the angles 0,45,90 and 135, and then Backproject using the method described in class ("by hand"). Note that you may not get the original matrix after back-projection. Compare to the results of the resulting matrices by applying radon and iradon functions in MATLAB with and without a filter. Filtering is only used during the backproiectin (iradon)
