xeno-spectral dataset

Welcome to the xeno-spectral dataset! This dataset contains semantically annotated spectral data from multiple species and three different perfusion states (physiological, malperfused and ICG). The HSI cubes were acquired with the Tivita® Tissue camera system from Diaspective Vision. Each data cube has the dimensions (480, 640, 100) = (height, width, channels) with the 100 non-overlapping spectral channels being in the range from 500 nm to 1000 nm at a spectral resolution of around 5 nm. This repository contains the raw data, related metadata as well as the preprocessed files.

Interactive visualizations

We provide interactive visualizations for every image in the dataset. This allows you to browse the dataset, visualize the annotations and search for specific images without downloading them. Further, the following PCA plots visualize every image in the dataset color-coded by species and symbol-coded by perfusion state. Click on a point to open the corresponding interactive visualization for that image.
