Finally, you will composite images, and add text on an image. You will then crop, grayscale, rotate, and blur an image. In this tutorial, you’ll use sharp to read an image and extract its metadata, resize, change an image format, and compress an image. sharp is a popular Node.js image processing library that supports various image file formats, such as JPEG, PNG, GIF, WebP, AVIF, SVG and TIFF. This article will focus on the sharp module. Node.js has an ecosystem of libraries you can use to process images, such as sharp, jimp, and gm module. With image processing, your application can resize and compress all the user-uploaded images, which can significantly improve your application performance and save your server disk space. This can negatively impact the application load speed, and also waste your server space. For example, if you’re writing a web application that allows users to upload images, users may upload unnecessary large images. It’s common for applications that handle user-uploaded content to process images. The process involves reading an image, applying methods to alter or enhance the image, and then saving the processed image.

The tool takes the whole trend in a new direction by allowing users to include rough sketches to inform the AI’s results.ġ0 things you need to know direct to your inbox every weekday. Last month, Meta revealed it was developing an AI tool called Make-A-Scene. Google Research unveiled its AI model Imagen earlier this year, saying it has an “unprecedented degree of photorealism” and a deep level of language understanding. TikTok is not the only company to jump on the AI text-to-image trend. Here are some test prompts for various political figures being assassinated… /AqKtQIRRkX The output is all so abstract, though, that it's unlikely to cause much harm. TikTok has a new text-to-image AI integrated directly into the app as a greenscreen filter. The Verge’s James Vincent noted that these images are “rather abstract and swirling”, differing from the photorealistic images and detailed illustrations that can be provided by other text-to-image models. TikTok also makes suggestions for those unsure what to type. You can type in anything you want, whether it’s a cultural reference or a version of a popular meme.Ĭlick ‘Create’ and an image will be generated based on the text. Next, a prompt will appear to type a few words. Type ‘AI greenscreen’ into the Effects search bar and select the logo that says ‘AI’. The new filter on TikTok can be accessed by pressing the ‘Effects’ button beside ‘Record’ on the app’s home screen. This open access tool spawned millions of memes and catapulted text-to-image tools to viral status.

While OpenAI only recently expanded early access to the tool, it inspired the creation of a similar image generator called the DALL-E mini, which was developed by machine learning engineer Boris Dayma. The AI system can create realistic images and artworks from simple word descriptions. The image can be used as a background for videos on the platform, which has more than 1bn monthly active users.ĪI greenscreen is being introduced on the tail of other text-to-image tools that have recently popped up, such as DALL-E by OpenAI.ĭALL-E was initially created last year and OpenAI introduced the updated version, DALL-E 2, in April. The new filter, which TikTok is calling ‘AI greenscreen’, allows users to type in a text prompt that it will use to generate an image. TikTok now offers a very basic text-to-image AI generator built into its app.
The new ‘AI greenscreen’ filter on TikTok is the app’s attempt to jump on the text-to-image trend popularised by the likes of OpenAI’s DALL-E.
