Another Go-To Place on the Web to Explore the Shroud’s Image

January 11, 2015 1 comment

Mario Latendresse’s Shroud Scope is still my favorite Go-To site for exploring shroud images (The Enrie and Durante 2002 images). But I must also praise the facility offered by the Diocese of Turin of the Haltadefinizione images on the web. It is another Go-To site.

imageAlthough based on the Haltadefinizione scans, it does not have the high definition quality of the iPad app, Shroud 2.0. But that is not what this web-based tool is for. It’s a simple, easy way for the public at large to explore the shroud’s image online. As a Go-To spot for the general public, it may be the best.

A few features:

  • As with Mario’s facility, you can move the image about – left and right, and up and down – by holding down the left mouse button and dragging the image about. Movement is smooth.
  • Also, as with Mario’s tool, you can zoom up and down with a mouse scroll wheel or with clickable buttons. Zoom sizes stated as percentages are simply relative values and have nothing to do with real size measurements.
  • To rotate the image 90 degrees simply click on the rotation buttons.
  • Four languages are supported at this time:  1) Italian, 2) English, 3) French and 4) Russian.  Clickable explanations of different parts of the images are excellent and they support on-the-fly Bing or Google translation into numerous other languages. Here is one example of an explanation:

The tool does not offer rectangle drawing for copying parts of images but that is unnecessary with simple tools that are now part of every standard operating systems (I used Window’s notebook for the above extracts).

Resolution looks good but the file is still very limited in terms of size (it need not be). If you want really high definition you will need to use Shroud 2.0 from which the following image of the epsilon bloodstain was taken in my iPhone. Yes, my iPhone! And then I doubled it just for the fun of it.  It is even bigger and better on an iPad. The app and image stream is available from iTunes. The app is free and the data is $3.99.

Significant Shroud.com Update

June 7, 2014 2 comments

It is a significant update.

imageI think the best way to take it all in is to go directly to Late Breaking Website News! Updated June 7, 2014 and start reading and scrolling. You might want to read the page straight through until you get to the last entry. It has a big red question mark and is about the next update.  Or you can click on the table of contents menu.

What a great update!  Plenty here to fill up a rainy weekend, and then some. I’ll comment and invite your comments on some of the update items in the next few days as I get around to blogging about them.

In an email sent to subscribers of the shroud.com mailing list, Barrie Schwortz writes:

This update includes seven more issues of Shroud Spectrum International, updates on the 2015 Shroud Exposition and upcoming Shroud Conferences, a new Tours to Turin 2015 page with listings of professional travel companies offering Shroud tours, links to many Recently Published papers and articles and some interesting surprises! We hope you enjoy the new information and find it useful. And don’t forget to visit our Private Subscribers Page for exclusive offers not available to the general public. You can also visit our Facebook page, which we try to update weekly.

Note: The link to Private Subscribers Page was changed to the sign up page link. The actual link is a perk for subscribers. So sign up.

Everyman’s VP8

Thank you for the update on ImageJ, the everyman’s VP8. The more I fool with it using everything from Enrie to Haltadefinizione images the more I clearly see that the images on the SOT are, by some measure of understanding, three-dimensional data. I cannot say that I’m convinced, as most shroud researchers seem to be, that the data represents body-cloth spatiality. In fact, I doubt it. It could be three-dimensional for many reasons.

It is not 1978 anymore. It is time to move on. We now have better images on the internet and better tools that are freely available to anyone in the world.  ImageJ does everything the VP8 does only faster, with more precision and with many more analytical options. Significantly, all data and settings can be automatically documented, shared and reproduced, which is something sorely lacking in the work done by Petrus Soons and Ray Downing. 

I have attached an interesting straight on view from a Durante picture using a magenta and yellow LUT to better see the effects of lighting from the left and above. Notice how sharp the eyebrows and lower cheekbones seem to be.

Update on ImageJ for 3D Image Analysis of the Shroud of Turin

June 4, 2014 Comments off

imageImageJ, your own VP-8-like image analyzer, is now easier to install and use except that you are going to have to get used to calling it Fiji. Fiji nonsensically stands for Fiji is Just ImageJ. Fiji is a packaging improvement. It is easier to install – just download a zip file, unzip it, and start it. And useful plugins are built right in.

ImageJ, is written in Java, which means you can run it on just about anything. This very powerful but easy to use graphics program was developed at the National Institutes of Health (NIH) in Bethesda, Maryland and is in the public domain. Downloadable distributions are available for Microsoft Windows, Mac OS X and Linux.

I downloaded the latest version from http://fiji.sc/Fiji, unzipped it, and had it up and running in less than ten minutes. 1) I launched the program using the provided program, 2) clicked on open a file, 3) selected an image of the face from the Shroud that I had saved to my computer, 4) clicked on Analyze > 3D Surface Plot and 5) tweaked some settings (see the image below – smoothing is essential).

It is highly interactive and re-plots 3D views almost instantaneously when you change a setting. You can drag the image right, left, up and down to change the viewing angle. It works with many image formats and, to my amazement, worked well with color and b&w images as large as 3072 by 2304 pixels and as small as 150 by 112.

Others including Colin Berry and Hugh Farey on this blog have used ImageJ effectively.  See: It’s a negative. It’s 3D. Yes? Maybe? Sort Of? and Should we be reassessing the VP-8 results (Continues Previous Post)

All Thumbs

June 3, 2014 1 comment

Works on any computer, not just the iPad

imageJoe Marino by email and Emanuela Marinelli in a posting to the Holy Shroud Guild Facebook page alert us to “Beautiful free Shroud pictures!” for your iPad. Just load The Shroud for iPad in Safari or Chrome and click on the front or back image. Then zoom away with finger and thumb actions. These are the Durant pictures, by-the-way.

BUT you can see these images in a regular browser on a laptop or desktop computer. And you can zoom them.  With the Chrome browser, I can zoom them up to 500%. Because I am running Windows 8.1 with a touch screen on a laptop (an early Fathers’ Day present) I can zoom or unzoom the pictures in exactly the same way with thumb and finger and drag them to and fro. Fantastic!

I just tried to do this thumb and finger zooming in Shroud Scope. Wow!  Fantastic!

I have just done a seven second comparison to the iPad app Shroud 2.0.  I like this better than the app (which has all those annoying watermarks all over the image). But then again, Shroud 2.0 has some good features and much better high definition based on scans of the shroud. It is a matter of what you want at any given time.
