[程式設計] 影像搜尋與處理相關API

Posted on 2011-08-15 by Allen

1. TinEye API TinEye 以圖找圖API簡介 TinEye API官網 說明：TinEye 的API目前看起來並沒有支援手機上使用版本。僅支援Python, Perl, Ruby, javascript, .NET等程式語言。 若要用他的手機版，得去使用他開發的PixID。(目前此版本還沒看到相關API) 2. Google Image API Google Image API說明：目前看起來只有提供輸入文字以搜尋相關圖片的API。 而Google Image Search 則提供了與TinEye一樣的圖片搜尋服務。不過相關API則是還沒支援，僅支援瀏覽器外掛版本。 Google 也提供了一些Java專用的圖形處理API: Image Java API ，專門替1MB以下圖片進行翻轉、刷淡、擷取縮圖等處理。 3. Google Picasa Web Uploader API 4. Imgur的Image Uploading API

Posted on 2011-06-14 by Allen
