Put your ear on the View Finder

Alexey Klimov (Алексей Климов) , photography expert and researcher, is using Feng-GUI to identify aesthetics in Synaesthesia photos, taken “from his ear” !

Feng-GUI have kindly given me possibility to analyze my exhibition photos.
I have use Feng-GUI to automatically search for pictures who most pleased the viewers. Almost all from them have shown a similar arrangement of zones of attention (hetamap). Thus, that the photographer style can be calculated without the aid of man-critics.


Synaesthesia - for some people letters are colored, numbers have a personality and when they hear music they see colourful images.
Synaesthesia explained at BBC http://news.bbc.co.uk/2/hi/7545888.stm









"I have started to photograph when I was eight-year old. It was the time of a black-and-white film and a house “red room” photo laboratory.
Since then I make at least one shot daily. I have read many books of known photo masters. I studied at art school.
But I have chosen other trade. The photo became my hobbies. Surprisingly, but my academic classical photos bored the viewers.

All has changed, when my wife has presented to me a mobile phone with the built in camera.
I began to photograph "from an ear" during telephone conversations. I aimed on hearing. Sight and all academic knowledge had a rest during such photographing. The man gets used to all. In three years I consider it natural to put the view-finder not my an eye, but to my ear. From hundred shots one turns out adequately. Such perfect shots it was typed on the whole photo-exhibition.”

Today I have developed ability "to photograph from an ear" to level of regular " view-finder photographing". Viewers began to speak about photographer's style. Experts began to speak about mixture of feelings (Synesthesia). The doctor of neurosurgery marks effect of dreams: when our eyes are closed we have dreams, just like babies. After all, when we dream, hearing is not blocked as sight.

Unexpectedly, I have found out Feng-GUI which helps me to automatically analyze my photos. Using Feng-GUI I have found a way to select the photos which most please the viewers. Now my Feng-GUI tested photos are printed in several Russian magazines. Photos which I take "from the ear" began to be attractive.



We like to see ourselves in group photo. If we don't find out ourselves in a photo then we value it as a documentary or art one.
When we see people in photo, the first thing that comes to our mind is 'Do I know them?' and the second is 'Who are they?'
The city life has accustomed us to see thousand strangers every day.
Our brain doesn’t store flashing persons in long–term memory to protect itself against overload.
And this habit is transferred also to taking photo.
Moreover, we distinguish people in our dreams on familiar or strangers, though we can’t remember their features and details after waking up.
For one thing, could you describe their ears, nose, eyes and lips if it was required to make an identikit for criminal investigation? :)



And still most of us, while having got a city intelligent habit 'don’t examine', 'don’t stare at stranger' and so on, remained wild animals in a our souls, and we expect everything of each stranger.
That’s why we learned to monitor life space about us by off–center vision, and using hearing and tactile perception in transport.
So how we can portray this point of view in photo?
Right in this manner, off–center vision–like.
You have to construct a shot so that the spectator didn’t look at an unfamiliar portrait, and was mown, intuitively listened, or even sniffed it.
So he didn’t stare at the person, like he’s looking at a monkey behind glass.
And the mathematics, 'queen of all sciences', allows to make it.

The first impression of a man is the strongest.
It is a wonder why nature and society together have developed this special first glance for creating a first impression of a stranger.
We do not stare straight at a person at the first encounter (unless we work in an HR department).
However, quick glances at the face, peripheral, panoramic view of a stranger's position in the interior, the elevated attention to information from all our senses — this is what provides the very first impression.
How to convey the first impression with a photo?
Especially, if the model is in fact well familiar to you?
The viewer does not have the intuitive barriers against staring at the monitor or the pages of a photo album.
The viewer can shamelessly eye a stranger's photo, feeling secure.

How to convey to the viewer the anxiety that he would experience if he met in person the man in the photo?

Real Virtual Skater


Another release is behind us, so this is time for some geeky stuff.
We took a real skateboard and converted it into a game controller .
Taking a real skateboard + a Wii remote and using it to control and "ride" the game "Tony Hawk Pro Skater" (THPS)

Slip me some skin, Bro!

Feng-GUI free attention heatmap service now includes skin detection.
Skin and Face detection have an important role in human visual attention.
It was already demonstrated in eye tracking sessions that face and skin are the first and the second spots that people tends to look at.

Checking “skin detection” will employ a combination of skin models and statistics to identify skin hue color in your image.

Do not use it unless you know that there is skin in the image.

Feng-GUI attention heatmap accuracy

We’ve been asked several times about the accuracy of Feng-GUI attention heatmap and why is it not reaching 100%.
Feng-GUI attention heatmap algorithm, which we call the ViewFinder , is a composition of algorithms aggregating over 30 years of research. Research from the fields of neuro-science studies, visual attention, statistics of eye-tracking sessions, perception and cognition of humans.
We improve the ViewFinder algorithm in order to achieve the highest accuracy, but is it possible to get to 100% ?

Let us answer by asking a question:
How accurate is the "Magic Wand" in Photoshop? (also referred as the “Fuzzy select” in Gimp)



The Magic Wand tool is designed to select areas of the image by finding edges of image segments.



Part of the answer to accuracy can be found at the "image segmentation and boundary detection" benchmark conducted by Berkley.
It’s a 1000 photos test suite for algorithms that try to find the boundaries of elements inside pictures.
In the test suite results you can see how real people and computer algorithms, marked the boundaries of segments inside photos and how accurate they are.
The current score is:
Real people: 79%
Machines algorithms: 70%

results:
http://www.eecs.berkeley.edu/Research/Projects/CS/vision/grouping/segbench/bench/html/algorithms.html

You can see that edge detection algorithms are not 100% accurate and will never be considering the hardware used be personal computers.
To solve this limitation, GIMP supports six different selection tools. In order of appearance in the tool box they are: rectangle, ellipse, free, fuzzy, bezier, and intelligent.
Each tool has its advantages and disadvantages--no one tool is clearly superior to the others. In general, a combination of tools proves to be the optimal strategy for complex selection tasks.

We conducted a comparison benchmark between Feng-GUI results and eye-tracking results of 40 people, 90 images, 15 seconds per image.
http://www.feng-gui.com/faq.htm#quality
Comparing the regions of interests (ROI) in the images, results with more than 70% of similarities.
If you compare Feng-GUI results to random groups of 10 people (out of the 40 people), for 5 seconds, the similarities go over 80%.

To enable designers and advertisers integrate Feng-GUI’s attention heatmap into their work process, we keep on improving the ViewFinder algorithm while maintaining two important requirements: Accuracy as well as Speed.

happy new year!
