EmpireJS: Hacking Art with Node js and Image Analysis

  1. Analyzing Japanese Art with Node.js and Computer Vision John Resig
  2. Lot 55: 20 Japanese Woodblock Prints Each depicting a female/Geisha figure with calligraphy throughout each print. Prints measure 13.75" H x 9.375" W. Toning to each print, some losses around edges. Estimated Price: $400 - $600
  3. Step 1: Acquire and read tons of expensive books.
  4. Step 2: Learn to read Japanese. * Japanese from the 17th to 19th century. * You’re not going to learn this from Rosetta Stone.
  5. Step 3: Learn to read Japanese calligraphy.
  6. Solution: A fast-loading, responsive, i18ned, web site: Ukiyo-e.org
  7. https://github.com/jeresig/i18n-node-2 var greeting = i18n.__('Hello %s, how are you today?', 'Marcus'); i18n.__n('%s cat', '%s cats', 3); Node i18n 2 (npm install i18n-2) setLocaleFromSubdomain([request])
  8. https://github.com/jeresig/i18n-node-2 {! "Hello": "Hello",! "Hello %s, how are you today?": "Hello %s, how are you today?",! "weekend": "weekend",! "Hello %s, how are you today? How was your %s.": "Hello %s, how are you today? How was your %s.",! "Hi": "Hi",! "Howdy": "Howdy",! "%s cat": {! "one": "%s cat",! "other": "%s cats"! },! "There is one monkey in the %%s": {! "one": "There is one monkey in the %%s",! "other": "There are %d monkeys in the %%s"! },! "tree": "tree"! }! Node i18n 2 (npm install i18n-2)
  9. Digital Ocean Amazon S3 Amazon Cloudfront Digital Ocean Images Data
 (HTML, XML, JSON) Images JS, CSS Images JS, CSS nginx (w/ cache) node.js express node.js express naught mongodb Elastic
 Search Scraper
  10. https://github.com/jeresig/jquery-imgscrubber
  11. Collecting Tons of Woodblock Print Data
  12. Search Page Page Page HTML Image HTML Image HTML Image Search Page Page Page HTML Image HTML Image HTML Image Queue-based Crawling using PhantomJS Processing Queue
  13. Some Website WebKit PhantomJS CasperJS SpookyJS Save Data XML Files Mongo Log libxml (+ xpath) MongoDB Extract Data Process Data Artists Images Correct Artist and Date Add to Site!
  14. module.exports = function() {! return {! scrape: [! {! start: "http://ukiyo-e.org/search",! visit: "//a[@class='img']",! next: "//a[contains(@rel,'next')]"! },! {! extract: {! "title": "//p[contains(@class, 'title')]//span",! "dateCreated": "//p[contains(@class, 'date')]//span",! "artists[]": "//p[contains(@class, 'artist')]//a",! "images[]": "//div[contains(@class,'imageholder')]//a/@href"! }! }! ]! };! };!

  20. Idyll: Offline Image Cropping • https://github.com/jeresig/idyll • Crop images offline and on a mobile device. • Saves the selections back to a server. • Data is synced and saved using HTML 5 appcache. • https://github.com/jeresig/node- appcache-glob

  24. Correcting Print Data
  25. Japanese Names • Utagawa Hiroshige • Ando Hiroshige • Andō Hiroshige • Hiroshige • 歌川広重 • 広重
  26. 安土 安堂 安島 安東 安籐 安藤 安道 安達 阿藤 Andō
  27. 安藤 andō antō anzō yasuzuka A many-to-many mapping!
  28. Sharaku Toshusai 東洲斎写楽
  29. Sharaku Toshusai 東洲斎写楽 Is this the family name? Where are the stress marks? How do you “split” this name? Which name parts
 correlate?
  30. Tools (all are Node modules!) • https://github.com/lovell/ hepburn • https://github.com/jeresig/ node-enamdict • https://github.com/jeresig/ node-ndlna • https://github.com/jeresig/ node-romaji-name ndlnahepburn enamdict romaji-name
  31. Hepburn • https://github.com/lovell/ hepburn • Takes in the English form of a Japanese word. • Returns it written in Hiragana or Katakana (phonetic Japanese alphabets). ndlnahepburn enamdict romaji-name うたがわひろしげUtagawa Hiroshige
  32. Enamdict • https://github.com/jeresig/ node-enamdict • Downloads and queries the ENAMDICT database • (A mapping of Japanese proper names to Hiragana and English.) • Used to correct typos and figure out surname/given name. ndlnahepburn enamdict romaji-name
  33. NDLNA • https://github.com/jeresig/ node-ndlna • Queries the NDLNA database • Finds the correct Kanji for an English name. • Or the correct English for a Kanji name. ndlnahepburn enamdict romaji-name
  34. ndlnahepburn enamdict romaji-name
  35. { "original" : "Sharaku Toshusai (東洲斎写楽 )", "locale" : "ja", "kanji" : "東洲斎写楽", "given" : "Sharaku", "given_kana" : "しゃらく", "surname" : "Tōshūsai", "surname_kana" : "とおしゅうさい", "surname_kanji" : "東洲斎", "given_kanji" : "写楽", "name" : "Tōshūsai Sharaku", "ascii" : "Tooshuusai Sharaku", "plain" : "Toshusai Sharaku", "kana" : "とおしゅうさいしゃらく" }
  36. Dates • https://github.com/jeresig/node-yearrange var yr = require("yearrange");! " yr.parse("1877")! // {"start": 1877, "end": 1877}! " yr.parse("1847-48")! // {"start": 1847, "end": 1848}! " yr.parse("ca. 1810-20s")! // {"start": 1810, "end": 1829, "circa": true}! " yr.parse("18th–19th century")! // {"start": 1700, "end": 1899}! " yr.parse("Meiji era")! // {"start": 1868, "end": 1912}
  37. Artist Rectification
  38. Miyagawa Shuntei Printed in 1897 Sold for: $550 Prints sell for $100-$400 individually True Estimate: $2100 - $8400 * * You just have to find someone willing to buy them!
