Abstract. Photographs of the back surface of the Turin Shroud were analysed to verify the existence of a double body image of a man. The body image is very faint and the background not uniform; i.e., the signal-to-noise ratio is lower than one. Therefore, image processing, developed ad hoc, was necessary to highlight body features. This was based on convolution with Gaussian filters, summation of images, and filtering in spatial frequency by direct and inverse bidimensional Fourier transformations. Body features were identified by template matching. The face and probably also the hands are visible on the back of the Turin Shroud, but not features related to the dorsal image. Keywords: image processing, very low signal-to-noise ratio, fast Fourier transform, convolution, Turin Shroud

The double superficiality of the frontal image of the Turin Shroud
So, basically, these guys are stating that after running photographs of the back of the Turin cloth through lots of image processing filters and doing a bit of tweaking, they were able to discern faint blurs that bled through from the other side.
That convinces me! It must be Jesus!
