ok .. tried out following setup:
* Thumbor Image processor
* Minio backend for storing images
* #Redis caching #server
wtf ... it's just fucking awesome. Let's take this image: https://images.mws.bka.li/RIFk8CMuG4CbQwwfLqGd4CGWL0A=/fit-in/x695/teleyal/Greybleb.png
I upload the original #image into the #Minio bucket via @nextcloud , set "fitIn" to the size I want and #Thumbor does the rest, including caching via Redis

Understanding millions of gates
Introduction to IC reverse engineering for non-chip-reverse-engineers.
#Reverse #Engineering of #integrated #circuits is often seen as something only companies can do, as the #equipment to image the #chip is #expensive, and the HR costs to hire enough reverse #engineers to then #understand the chip even more so. This talk gives a #short #introduction on the #motivation #behind #understanding your own or someone else’s chip (as a chip manufacturing company), and why it might be important for the rest of us (not a chip manufacturing company). The #focus is on #understanding what #millions #of #logical #gates #represent, rather than the physical aspect (delayering, imaging, image processing…), because everyone can do this at home. I will introduce some #proposed #countermeasures (like logic encryption) and #explain if, how and why they fail.
The #talk will give a #general #overview of the #research #field and #explain #why #companies #are #interested #in #reverse #engineering #ICs (IP overproduction, Counterfeits, Hardware Trojans), as well as why it’s important for an end user (IC trust, chip failure). Then, I will very shortly introduce the #reverse #engineering #workflow, from #decapsulating, #delayering, #imaging, #stitching, #image #processing and then come to the focus: #netlist #abstraction. The idea is to show some #methods which are #currently #used #in #research to #understand #what #netlists #represent. Some #theory will be #explained (#circuit #design, #formal #verification of #circuits, #graph #theory…), but I want to keep this to a #minimum. Finally, I will show some #current #ideas on #how #to #make #reverse #engineering #difficult, as well as #some #attacks on these ideas. The talk does not give insights into how large companies do reverse engineering (i.e. #throw #money #at #the #problem), but rather #show #the #research #side #of #things, with some of the methods published in the last couple of years, which is #something #everyone can do at home.

#AI #DeepLearning #vision #Python #Google #image #EXIFThe dumb reason your fancy Computer Vision app isn’t working: Exif Orientation
Exif metadata is not a native part of the Jpeg file format. It was an afterthought taken from the TIFF file format and tacked onto the Jpeg file format much later. This maintained backwards compatibility with old image viewers, but it meant that some programs never bothered to parse Exif data.
Most Python libraries for working with image data like numpy, scipy, TensorFlow, Keras, etc, think of themselves as scientific tools for serious people who work with generic arrays of data. They don’t concern themselves with consumer-level problems like automatic image rotation — even though basically every image in the world captured with a modern camera needs it.
This means that when you load an image with almost any Python library, you get the original, unrotated image data. And guess what happens when you try to feed a sideways or upside-down image into a face detection or object detection model? The detector fails because you gave it bad data.
You might think this problem is limited to Python scripts written by beginners and students, but that’s not the case! Even Google’s flagship Vision API demo doesn’t handle Exif orientation correctlyThe dumb reason your fancy Computer Vision app isn’t working: Exif Orientation

Article content:1060 is the number of hours needed to capture this highly-resolved image (204 Megapixels) of the Large Magellanic Cloud. It might be the worldʼs longest exposure image within the amateur astronomers community.
In astrophotography, the amount of time you spend imaging a celestial object is inherently fundamental. The longer your cameraʼs shutter is open, the more light you get, so that the darkest regions of the sky start to get clearer. Usually, amateur astronomers are familiar with very long integration times, such as few minutes or even few tens of hours. However, reaching a total amount of several hundred hours increases the complexity of image processing and therefore remains quiet rare... though, five keen amateur astrophotographers challenged themselves and decided to capture a picture of 1060 hours of total exposure time, which can be considered as a world record (professional astronomy excluded).
This image is not only a technical accomplishment, but brings also a scientific interest to one of the most amazing deep sky object of the Southern sky : The Large Magellanic Cloud (LMC).
The image is a mosaic made of 16 smaller fields of view, which, once stitched together form a high-resolution image of 204 Million of pixels! As of matter of fact, this is not the work of a single person but by a team of five french amateur astronomers called "Ciel Austral": Jean Claude CANONNE, Philippe BERNHARD, Didier CHAPLAIN, Nicolas OUTTERS et Laurent BOURGON.
"Ciel Austral" owns a remotely-controlled observatory located in the most prestigious skies of the planet, in Chile, and more precisely at the El Sauce Observatory (Coquimbo Region). A 160-mm APO-refractor telescope and a Moravian CCD were used to obtain this wonderful field. The datasets were taken over several months, ranging from 2018 and 2019. The heavy files handled represent 620 GB and needed few hundreds of hours to get out of the image processing step! Once stacked together, they make up the stunning figure of 1060 hours of exposure. If you are more curious, we invite you having a look at [1]their official website here.
You certainly noticed the color-rendering of this image is quite unusual. Indeed, astrophotographers used a couple of special filters which transmit narrow parts -lines- of the visible spectrum : the Hydrogen Alpha line at 656 nm, the Sulfur line at 672 nm and the Oxygen III spectral line at 500 nm. These kind of filters enable to emphasize chemical components located in high-density gas regions like nebulae, what standard RGB imaging can not perform.
Settled in Chile since 2017, the Ciel Austral Observatory gives to this 5-member team a way to expanding their knowledge and skills in astronomical imagery in order to fulfill its most ambitious projects. So, one should stay tuned for more of their upcoming fantastic images.

[IMG][3]Picture of the LMC in RGBHaO color rendering, taken by Ciel Austral team.
This image shows us a unique view of the most famous night-sky object for Southern-Hemisphere astronomy. The LMC is actually a satellite neighbor of our Milky Way galaxy pretty close to us, at 50 kilo-parsecs distance (163k light-years). Scientists estimate it will do a full orbit around us in only 1.5 Billion years...
The Large Magellanic Cloud belongs to the Local Group - a list of about 50 galaxies close to each other, including our own.If you have the opportunity to spend a night under the Southern Skies, this naked-eye-visible object will surprise you by its wide angular size and its strong brightness: LMC covers a slice of the sky which can contain 20 moon diameters, shining at a 0.9 magnitude!

Went on another much longer #walk along the #Otago #Peninsula...
Turns out that the pedestrian walkway along the #sea ends abruptly about 1.5km in, so I had to follow the #suburbs #uphill.
I stumbled my way to rotary #park and the rotary club lookout point and had a nice rest.
Then I followed Highcliff Rd back to #dunedin
