Scientists have developed a new camera system and open-source software that allow them to generate captivating video clips showcasing how various animals perceive the world. By emulating the specific colors perceived by different species, the footage offers a unique glimpse into their visual experiences.

The researchers published a total of 12 videos demonstrating how birds, bees, mice, and dogs see their surroundings. The videos showcase scenes within a garden environment, with colors accentuated or dulled depending on the animal's vision being emulated. One of the clips features a zebra swallowtail butterfly foraging on flowers, displaying how a honeybee would see it.

To produce these videos, the scientists set up cameras to capture raw footage and then utilized post-processing software to predict perceived colors in different animal species. This novel method, outlined in a paper published in the journal PLOS Biology, has shown an impressive accuracy rate of 92% compared to conventional spectrophotometry techniques.

Daniel Hanley, senior author of the study and an assistant professor of biology at George Mason University, expressed fascination with understanding how animals perceive the world. He highlighted how animals often make crucial decisions in dynamic environments, emphasizing the importance of capturing and displaying animal-perceived colors in motion.

Different species perceive the world differently due to the photoreceptors in their eyes and the neural architecture of their brains. For example, dogs have similar eye structures to humans with red-green color blindness, while insects like honeybees can detect ultraviolet light.

Previous methods aimed at reproducing animal-perceived colors have only been capable of generating still images. Techniques like spectrophotometry estimate the colors detected by an animal's photoreceptors using object-reflected light, while multispectral photography provides more spatial information but only works on still objects.

To overcome these limitations, the researchers utilized commercially available Sony a6400 cameras configured to record in four color channels: red, green, blue, and ultraviolet. This initial step allowed them to capture the raw footage, which was then processed using the video2vision software. The software applied transformation functions to render the video in animal-perceived colors, with each "perceptual unit" fine-tuned based on knowledge of the respective species' photoreceptors.

Scientists and filmmakers interested in studying animals can now use this camera system and software to capture and process their own footage. By applying animal-vision filters to their recordings, researchers can gain further insights into how particular species interact with their environment and respond to stimuli.

This breakthrough in capturing animal-perceived colors in motion opens up new possibilities for understanding the visual experiences of different species. The videos produced using this innovative system are not only visually stunning but also provide valuable insights into the fascinating world of animal vision.
