Re:Geometrize: Turn Images into Geometric Primitives on Sunday December 20, 2020 @07:05PM (#25490814)
There was a challenge at stack overflow to encode an image in a tweet (140 characters at the time):

Some of the solutions took a similar approach that used geometric primitives.

Re:Who's downloading pirated papers? Everyone on Friday April 29, 2016 @10:49AM (#11596063)
Most journals require that the authors sign an agreement in which the publisher retains the copyright of the paper (e.g. [1]).

Although a few publishers allow the authors to provide a pdf of the paper in their personal home-page, they do allow it to be uploaded to an open access platform.

I also think that Anaconda is great. However, I hope that in the future we could install numpy, matplotlib, jupyter, etc. just using pip.
Flickr was -- and maybe still is -- very useful for the computer vision research community.

"Mining of Massive Datasets" by Leskovec, Rajaraman and Ullman is very good.

Although the post gives a link to the Amazon page of the book, PDFs of the chapters are free to download at the official book web site[1].

My first impression was the same as Mithaldu, but then I tried one of the other games and it was more responsive.

I think that the NES emulator is bad advertising for your (very nice) product.

A challenge would be that coffee trees have very deep roots [1].

I have the impression that Pepsi is much more popular in US than in Brazil.
"However, yet another recent theory proposes that grasses competing for water and nutrients - limited resources in the Namib desert - create the circles, explaining why they never overlap."

Maybe this model could be used to analyze this hypothesis.

Nice, but I think it is not real, just marketing for the new Planet of the Apes movies.
Re:Perceptual Image Hashing on Friday August 08, 2014 @05:08PM (#8155054)
Very interesting approach.

I have worked with image feature extraction in the past. Although using DCT coefficients has been used as a way to analyze texture features, the idea idea of generating the hash (step 5) seems to be new.

I am curious however on why you are discarding color information. Usually for reverse image search this kind of information can be quite useful.

Re:Optimal streaming histograms on Wednesday August 06, 2014 @02:22PM (#8143999)
Log-binning can be useful. However it has some disadvantages.

I think that in your case your data (server response time?) looks good because you probably have a log-logistic or log-normal distribution.

Suppose you were working with values that are exponentially distributed which is also a reasonable hypothesis for your data. In that case the log-binned histogram would like a plateau with the exception of the beginning and ending bins. In this scenario a linear-binning approach would probably be better.

Unfortunately, I think that there is no approach for bucketing that is good for all situations. Usually the best approach will depend on your data and also on what you are trying to analyze.

Re:Euclid: The Game on Friday June 20, 2014 @03:18PM (#7922365)
Very nice game.

One problem for me is that by default the comments from other users are shown, sometimes with the solution for the level.
