Automatically and accurately remove red eye from user uploaded photos

Apr 16, 2015 by Nadav Soferman

Automatic red eye removal Red eye often happens due to the use of flash in low light conditions as the light hits the eye very quickly and into the retina. It then bounces off of the back of the eye and emits a red color due to the blood vessels there. Although more professional modern cameras and flashes generally prevent this from happening, red eye may still occur with simpler, smaller cameras (including smartphones). There are various software solutions for red eye removal available on mobile devices and desktops, some of which require manual processing to get good results.

Apr 08, 2015 by Nadav Soferman

Anti-malware icon Social networking sites allow users to upload images or other types of files that are immediately available to other users via news feeds or notifications. In some cases, attackers can directly spread infected files, but more commonly, they leverage the viral effect and the fact that users are simply unaware that their files are infected through sharing and collaborating with others. As a site owner or application developer, it is your responsibility to protect users and prevent these situations from occurring. Fortunately, Cloudinary makes this easier with its Metascan add-on.

How to automatically and professionally remove photo backgrounds

Mar 26, 2015 by Nadav Soferman

RTB add-on It is common for e-commerce, media, and news sites to remove image backgrounds or make them transparent in order to place the main element of the image on either white or color backgrounds. The final result better integrates an image into a site or specific page’s graphic design. For example, a fashion site that presents clothes or shoes should have the main element of a photo (e.g. shoes) extracted from the original image background, then edited to fit the site’s catalogue design and structure.

Transform your image overlays with on-the-fly manipulation

Mar 19, 2015 by Nadav Soferman

Layer apply Front end developers may want to combine multiple images into a single image. For example, when creating and adding watermarks to stock photos, adding shapes or badges, preparing content for print (e.g. placing a logo on a t-shirt or a mug), adding a caption, and so on.

Multiple images can be combined by overlaying them one on top of the other. However, since it is not a given that both the underlying and overlaying images match each other, let alone your graphic design, you may need to perform further manipulations (e.g. resize, crop, change colors, create a better fit). This is where Cloudinary comes in.

How to dynamically create SEO friendly URLs for your site's images

Mar 11, 2015 by Nadav Soferman

SEO friendly image URLs Image URLs tend to appear as a long list of random characters that are not intended for viewers and are not very useful to search engines. Concise and meaningful image file names are better for search engines to extract information about an image, therefore supporting your site's SEO ranking.

Often times, users' uploaded image files do not have descriptive names. This creates a great challenge for developers and site content managers who need to maintain SEO friendly, short, and meaningful URLs. Cloudinary helped tackle this issue by offering users two new features: Root Path URL and Dynamic SEO suffixes. These features can be useful for website as well as web application owners, and are especially recommended for content-heavy sites, like online magazines and news sites.
