Same as last post www.flickr.com/photos/kylemcdonald/4309938058 but using an alternative method for FFT frequency estimation, described here www.dspguru.com/dsp/howtos/how-to-interpolate-fft-peak
Unfortunately it's still really wavy (see bottom right). I didn't expect that recovering a single frequency would be so difficult. Maybe another technique, like autocorrelation, should be used instead in cases where non-transparent materials are being scanned?
paddedAmplitude = [zeros(1, w); amplitude; zeros(1, w)];
[maxVal, maxInd] = max(paddedAmplitude);
ph = size(paddedAmplitude, 1);
pw = size(paddedAmplitude, 2);
y1 = paddedAmplitude(maxInd - 1 + ph * ((1:pw) - 1));
y2 = maxVal;
y3 = paddedAmplitude(maxInd + 1 + ph * ((1:pw) - 1));
binOffset = (y3 - y1) ./ (2 * (2 * y2 - y1 - y3));
subplot(2, 2, 4);
plot(maxInd + binOffset - 1);

Swedish Ambassador to Bangladesh H E Charlotta Schlyter, Ms Carin Zetterlund, First Secretary/Deputy Head of Development Section and Ms Lena Nordström, Head of Staff MoFA visited icddr,b’s Matlab field site - one of the developing world’s richest, most comprehensive and longest-running data resources.
The guests visited icddr,b health and demographic data collection facilities, ongoing studies in the villages, the Matlab hospital, especially providing services for women and children and a mother care unit.
The guests also took a boat ride to Matlab, using the same route once taken by hundreds of thousands of cholera patients from remote areas to reach icddr,b’s floating hospital on a barge, which now remains parked at Matlab, bearing witness to the history of humanitarian efforts.

El jueves 17 de octubre, de 10 a 13.30 horas, en la Escuela de IngenierÃa de Telecomunicación y Electrónica de la ULPGC, se va a celebrar un Seminario de Matlab, a cargo de Loren Shure, coautora de varios productos de MathWorks donde ha trabajado en los últimos 30 años.

Derived from part of the Patrick Lichfield B&W portrait taken in 1980 and (at the time of posting) on display in the National Portrait Gallery in London. This is realised by 96 x 96 bricks, equating to 768mm x 768 mm using standard sized 1x1 studs.
The image was generated using software I have developed to convert photos into lego mosaics. The software began life in Matlab but is now a macos/Windows app developed in C++ using the Qt framework.
The ambassador visited the hospital located inside the Matlab Health Research Centre where he spent some time touring the diarrhoea, and maternal and child health wards.

Norwegian Ambassador HE Ms Sidsel Bleken and Norwegian Institute of Public Health officials visited Matlab Health Research Centre to learn more about Hepatitis E Vaccine HEV study led by icddr,b senior scientist Dr K Zaman, and different maternal and child health services and Matlab hospital. The visitors also went to the field to see how community health research workers are engaged in routine HDSS data collection in the villages. Photos: Rabiul Hasan
Black bars drawn recursively on a grid.
Although I often create images like this in Processing, I made this one in Matlab.

Scherk's surface is defined by exp(z)cos(x)-cos(y)=0. If z is treated as a complex number rather than a real and multiplied by exp(it) the solution to Re(exp(z)cos(x)-cos(y))=0 performs this curious dance act. The color denotes the imaginary part.
This set works nicely as a slideshow.

but reprocessed by some homemade effects that I tried to implement with Matlab and that works surprinsingly good. If you're interested in these effects (it basically increases the contrast), please contact me...

I call my newest invention "The Smile-O-Tron 5k".
And here is what you do: Train you system (eigenfaces) on smiling people, then take an image with serious faces, find them, project them into face space and back, and tadaa: They are smiling! Happy days!
Below you can see the reconstruction error near the actual faces.
