You can also select multiple annotations by clicking, holding, and dragging the mouse to draw a rectangle around the desired annotations. To cancel an annotation, hit “Cancel” on the canvas or press “Escape.”Īfter choosing the Pointer selection tool on the top of the right toolbar, simply click on any annotation to select it. After each annotation, either hit “Confirm” on the canvas or press “Enter” on your keyboard to confirm the annotation. To create a new annotation, simply select the desired annotation tool on the toolbar on the right and start annotating regions of interest. The size of these superpixels can be varied using its corresponding brush size slider. This tool fills regions based on similarity to the color of the selected pixel.įinally, the quick selection tool allows users to quickly annotate objects by selecting superpixels (a group of pixels that share common features) pre-computed from the image. To annotate regions that are distinguishable by their color against the background, use the color annotation tool. Use the magnetic tool for cases where the object to be annotated has visible edges the tool will automatically snap to these edges! The pen annotation tool, with a customizable brush size, allows for freehand drawing.įor more intricate shapes, use the lasso tool to draw around the boundaries of an object and release it when ready to close the annotation. The rectangular, elliptical and polygonal annotation tools draw simple geometric shapes around the objects of interest. Check out a demo of a few of these functions here.
Piximi Annotator includes a variety of annotation tools to enable sensitive, specific annotations on a vast variety of image inputs. While developing Piximi Annotator, one of our objectives was to provide an intuitive interface which provides useful controls without overwhelming new users. tiff file formats images can have either 1 or 3 channels and currently are supported in 2D only (with 3D support coming soon). No account or installation whatsoever is required, just drag an image (or multiple images) to your browser window and start annotating right away! Note that all images used in Piximi remain local on your computer they are not uploaded to any server nor shared with us in any way.
Wait…aren’t there already lots of annotation tools out there?Ībsolutely! And many are great, but we needed a browser-based annotation tool that is easy to use and keeps all data local, which motivated us to create Piximi Annotator.īecause Piximi Annotator is a web application, it is easy to access: simply open your favorite browser and click on this link. Annotations are useful when training machine learning models to recognize specific structures and objects in images.

We’re delighted to release Piximi Annotator, a new image annotation tool that we built to be easily accessible, easy to use, yet with a full complement of annotation tools to allow for specific, refined annotations.
