You can read more about all the new features and bug fixes in the Label Studio 1.7.2 release notes. We’ve made improvements to the audio labeling interface that allow you to load and annotate audio files up to 5 hours in duration. This makes labeling overlapping audio segments (such as multiple people talking at same time) visually and functionally easier to annotate. This new feature allows users to visually separate each channel of a multichannel audio recording. We’ve added two major features to our Audio annotation functionality that make Label Studio even more useful for audio labeling use cases.

You can see it in action here:Ī big thanks to the Planet Labs team, who created and submitted this feature! Read more about how to get started with the magic wand tool in the Label Studio docs! Improvements to Audio Annotation For these use cases, this tool can significantly improve your labeling speed and accuracy. It is particularly effective at labeling broad, diffuse, complex-edged objects, such as clouds, cloud shadows, snow, and so on, in Earth observation applications or organic shapes in biomedical applications. The tool allows you to easily zoom for fine-grained detail and scan the zoomed-in image while still remaining highly performant. This new community-contributed feature makes it possible to click in a region of an image for segmentation labeling, drag the mouse to dynamically change flood filling tolerance, then release the mouse button to get a new labeled area. When you put your eyes where the screen was, light from only a small part of the image enters your eye, so you cannot see the entire image.Label Studio 1.7.2 introduces a new Magic Wand tool for image annotation and significant updates to our audio labeling functionality. Your eye can only make images of the light that actually enters the pupil. The light in most projectors is too bright to try this experiment. You might wonder if you could see the image by looking directly into the slide projector from the place where the screen used to be. The resulting deformations are like those that occur when the spherical surface of the earth is mapped onto a flat map. The planar image from the computer or slide is projected onto a curved surface. The deformed images produced when you move the wand in the shape of a cylinder or cone are examples of a map projection. Persistence of vision occurs because the light detectors in your eyes, the rods and the cones, continue to fire electrical signals to your brain even after a very short pulse of light has come and gone. Your eye’s tendency to hang onto an image for a fraction of a second is called persistence of vision. Your eyes retain each piece of the image for about 1/30th of a second-long enough to let you put the pieces together to make a composite picture if the wand is moving fast enough.
When this reflected light enters your eyes, it makes an image on your retina. The moving wand reflects the light just as the screen does, except that the wand reflects the image piece by piece. The image you’re projecting is focused in the air, but you can’t see it unless something reflects the light to your eyes.
