XKCD-like comics on Compressive Sensing in MRI

Miki Lustig just sent me the following: 

Hey Igor,

While being in a creative mood recently I made a comics describing the principles of CS in MRI. It's linked from my CS page.

Thought you might be interested. 

Have a nice week!

Outstanding Miki! I'll add it to the Learning Compressive Sensing page. The series of comics starts here. You need to click "next" below each comic to get to the next one.

Join the CompressiveSensing subreddit or the Google+ Community and post there !

CS: Post-Doc at Lawrence Berkeley Labs.

Stefano Marchesini wants to let y'all know about this Post-Doc fellowship opportunity at Lawrence Berkeley labs:

Physicist Postdoc Fellow (X-ray Coherent Imaging and Scattering)
Req Number:

The Advanced Light Source Division (ALS) at Lawrence Berkeley National Laboratory (Berkeley Lab) offers an exciting postdoctoral fellow opportunity to conduct experiments at the ALS and develop experimental and theoretical methods for x-ray coherent imaging and scattering. This position reports to the Coherent Imaging lead scientist within the Experimental Systems Group.

Key responsibilities include:

• Develop experimental and theoretical methods for x-ray coherent imaging, holography and general scattering.
  
• Communicate work results via reports and oral presentations, including participation in meetings, reviews, conferences, and publications in refereed journals.

Qualifications include:

• Ph.D. in Optics, Physics or Engineering within the last 2 years
  
• Experience with complex experimental apparatuses such as synchrotron beamlines and/or optical measurements
  
• Familiarity with signal processing (phase retrieval, compressive sensing) and/or familiarity with experimental techniques of synchrotron radiation research is advantageous.

Note : This is a one-year term appointment with the possibility of renewal after one year based on demonstrated performance and availability of funds.

Thanks Stefano !
I'll add it to the Compressive Sensing Jobs page later.

CS: Freefalling, Hardware at 130,000 feet, Statistics on a cartoon, and a Silicon detector.

Here is a fantastic rendering of what it would look like to fall from Space (for those of you reading this through e-mail or an RSS feed, here is the direct link)

This reminds me that you don't need a rocket to go up. Stratospheric balloons do that very well as can be seen from the view of a webcam that was on-board the HASP last year.

For those of you interested in having some hardware at those altitudes, you may be interested in the new request for proposal by the HASP folks. The deadline is Dec. 19th.

The first cartoon video on CS has reached more than 1000 viewers (950 times being me hitting that replay button). The statistics provided by Youtube provide some insight about when the interest of the reader was the highest. I am not sure how they compute this but the first bump in this video is when CS is connected to underdetermined systems and linear algebra 101.

The video can be viewed here:

Finally, a video on a type of photon detector made out of Silicon that seems to have reached some breakthrough. More pixels, lower cost is our future, how can we integrate this in new types of CS cameras ?

CS: Mind Mapping Local Compressive Sensing Resources

To the untrained eye, it may look like I am generating a new page every week. It may well be the case. In order to give a better bird's eye view of the current pages I have created on the subject, I have mindmapped all these pages using mind42.com (see map below). The same schematic with attendant links is also available in a Freedmind format here.

Saturday Morning Cartoon: Current Compressed Sensing Hardware, Episode 2

The first episode of the Saturday Morning Cartoon has already been viewed 193 times. This week's Saturday Morning Cartoon had to be cut in three parts. Most of the in-depth material can be found on the Compressive Sensing Hardware page.

Part 1



Part 2



Part 3



The scenario can be found here. The Saturday Morning Cartoon series can be found here.

Saturday Morning Cartoon: Explaining Compressed Sensing, Episode 1

[Update: For non-english speakers, it might be hard to follow some of the rapid exchange. The scenario can be found here]

I am continuing this small experiment of featuring two cartoonish characters talking about compressed sensing. The result ?....I am not quitting my day job :-) 

The scenario is based on different questions I generally get asked when grilled on the subject. If you have a friend, a colleague or a student who wants to know more about the subject but do not have time to read a paper, this might be a way to go about initiating their interest.

I am looking for ideas for the next one. If you have questions that have been asked from you several times and for which you have gotten better at answering, send me your scenario, I'll try to render it and will put it in the Saturday Morning Cartoon Series at:

In the meantime, here is this week's product.

Is it any good ?
