After defining "a" as a simple utility function to convert JSON to associations, I'm quite pleased with the readability improvements allowed in v10 to the code to import category members from Wikipedia.
a[list_] := Replace[list, a : {__Rule} -> <|a|>, {0, \[Infinity]}]
Ok, I updated the random premise seed selector to use 10,000 important Wikipedia articles instead of a dictionary. The results are definitely easier for your mind to latch onto, but still take thought to find a fun way to stitch them together. 3 articles and 2 tropes.
Okay let me tell you my story of why I'm doing the weirdest problems. I'm 15 years old and used Mathematica to do simple planetary simulations for my Science Fair and won 1st place. Now I wanted to take my Mathematica knowledge to the next tier and compete in Intel Talent Search contest. To prep myself up, I bought a book full of exercises, but only has solutions to some difficult problems. I guess this isn't too difficult for the author. Whenever I have trouble, I seek help from my great friends on the InterWebs.
@mildused Not necessary, I can imagine that. Morphological ops are needed indeed. But not enough. First go to Wikipedia and read about the "Hough Transform"
Then, go to Mathematica and read about "ImageLines[]"
Then, think about how to combine a Hough Transform with some Morphological ops
Reading that kind of things "lightly" i.e. trying to learn how to use it but not understanding how it works impedes you from achieving a superior mindset
Graphics are tightly integrated into the Mathematica interface. The Front End is programmable, and Mathematica has functions to interface with the web, so the question naturally comes up:
Could we make it possible to upload images to StackExchange directly from Mathematica, using a palette butt...
@mildused Anyway, that's a real life problem.Not one the author thought for you to learn. It's interesting, but doing it really well will take you a lot of time
with THAT kind of image
If you post the problem at the site,someone will solve it for you. But I don't think it as a standard procedure for learning
I came across an exercise in one of the online tutorials for Mathematica and can't solve this Image Processing Problem.
The files I reference to are attached.
I have the Music Sheet (01Original.TIF) and am trying to produce the images 01Notes.TIF and 01StaffLine.TIF.
I know that once I get eit...
@mildused you've probably figured it out by now, but you can change the sound notifications by clicking on the black speaker icon at the top of the banner to the right of this chat.
@mildused Well, you said it was slow. It's OK if it's slow and you only have to do it once but while you are experimenting you can take a part of the image that is not too large and quickly try different transforms on it.
I've been experimenting a bit on your images using the Radon transform and it's pretty fast because I only use a part of the image to experiment on.
@Pickett I'm only 15 years old. Can you dumb it down for me? You want me to take a piece of the picture. I can do ImageTake[]? and then just keep using that the whole time. I can ImageTake like the first line of the music?
There is a built in tool for cropping images. Just select the image and then "crop tool" from the toolbar that appears underneath the image. This is the image I use to experiment on:
@mildused My code didn't work very well on your image. I would copy the code in the video (it's a fair bit of code, but probably more robust and faster) or try removing peaks from the Fourier transform like someone else suggested.
@PatoCriollo I'm watching it right now. It's great but it didn't work on my example as well. I even decreased the threshold involving duplicate lines to overlay on the staff lines but some lines just don't pick up.
@PatoCriollo I was also a tad bit disappointed by Marilyn S. and Arnold M.
