Cloudflare Images

Cloudflare Images 開放付費使用了:「Cloudflare Images Now Available to Everyone」。

檔案傳到 Cloudflare 上面,然後另外收處理費用:

You pay $5/month for every 100,000 stored images and $1 per 100,000 delivered images. There are no additional resizing, compute or egress costs.

檔案大小的限制是 10MB,所以 $5/month 的 storage 最多可以提供 1TB 的空間,$0.005/GB 算是很漂亮的數字,如果是小圖的話就會比較虧一些?看起來丟大圖會開心一點...

Cloudflare Images offers multiple ways to upload your images. We accept all the common file formats including JPEG, GIF and WEBP. Each image uploaded to Images can be up to 10 MB.

然後支援的檔案格式有常見的 GIFJPEGPNG 以及 WebP

When a client requests an image, Cloudflare Images will pick the optimal format between WebP, PNG, JPEG and GIF.

另外有計畫要支援 AVIF

We’re just getting started with Cloudflare Images. Here are some of the features we plan to support soon:

AVIF support for even smaller file sizes and faster load times.

沒提到 durability,不知道會有多少...

Google 整理並公開出九百萬張圖片以及對應的 tag

Google 放出了九百萬張以 CC 授權釋出的圖片,標上 tag 後變成 Open Images dataset:「Introducing the Open Images Dataset」,像是這樣:

Annotated images form the Open Images dataset. Left: Ghost Arches by Kevin Krejci. Right: Some Silverware by J B. Both images used under CC BY 2.0 license


The image-level annotations have been populated automatically with a vision model similar to Google Cloud Vision API.

不過因為這不是人工確認過的資料,如果要拿來做比較精確的研究,還是得用 Amazon Mechanical Turk 這類服務先校正過以確保正確性。
