Various Consequences

Wow, the user friendliness and speed of this app is just amazing. A long way in ease and useability from the open source tool chain I...

  The data set he mentions is Johns Hopkins Turbulence Databases . Many hundreds of Terabytes of direct numerical simulations with dif...

This is an interesting summary of an approach for shape segmentation. I think it's pretty cool how often VGG-16 gets used for transfer...

Topology Optimization Data Set for CNN Training Neural networks for topology optimization is an interesting paper I read on arXiv that i...

senseFly mapped the Matterhorn with a bunch of little UAVs. Pretty impressive photogrammetric point cloud: 300 million points!

More photogrammetry. This uses the same software tool chain I described before . Still needs a bit of work on surface reconstruction. I a...

Bundler-PMVS2 Dense Point Cloud Visualization in Meshlab I wanted to experiment with some free photogrammetry software, and the Masonic T...

I thought the intermittent splashing of the cooling water/steam in the close-up portion of this J2-X engine test video looked interesting. ...

Tikhonov regularization is a pretty cool concept when applied to image processing. It lets you 'de-blur' an image, which is an ill-...

The real world is noisy, and the differencing operations of edge detection tend to magnify that noise. We can apply some statistical method...

There are some good examples floating around of creating customized image processing kernels in the python imaging library (PIL). It'...

In image processing the discrete difference operators to calculate gradients and second derivatives are called "masks". They are o...

I can't really decide on the best way to treat the different channels (red, green, blue) in a color image when doing edge detection. I...

That's the Python Imaging Library . I demonstrated a couple of edge detection techniques ( gradient and laplacian ) using the PIL to ...

In Poor Man's ADC Revisit , I demonstrated gradient based edge detection using Python's Imaging Library to read in a jpg. You can a...

I wrote a bit ago about using a webcam as an analog-to-digital converter . The really quick hack I put together used Octave's built-in...

Can you use a commodity webcam as an el-cheapo analog to digital converter (ADC)? The folks at slashdot want to know so they can reduce the...
