Dynamic Appearance Dataset

We release a dataset of time-varying appearance such as rusting, drying, melting, molding, etc.

Links Description Size
RGB_dynamic_textures 22 dynamic textures with time-varying visual statistics; Each is 5s GIF; 2.2G
SVBRDF_dynamic_flash_textures 21 flash-lit videos of time-varying materials; each has 100 JPG frames that are equally-spaced sampled from raw data; 12.8G
RGB_dynamic_textures_raw Raw data for dynamic textures 7.4G
SVBRDF_dynamic_flash_textures_raw Raw data for flash-lit videos, including raw photographs for captured data and Blender scenes for synthetic data 118.3G

To run our codebase, please donwload the first two ready-to-use datasets.

Capture Setup

For those interested in capturing flash-lit time-lapse videos on their own, our setup is lightweight and accessible, requiring only:

  1. A (programmable) camera with a flashlight close to the lens (co-located). Typically, your smartphone will suffice. For iPhone, we recommend using the CameraPixels app;
  2. A tripod to stabilize the camera;
  3. An optical cover to block unwanted ambient lighting;
  4. Your time-varying materials of interest. We provide some protocols to reproduce the materials we captured.

decaying_melon Captured by us from 2023 Oct 7 to Nov 13

For dynamic flash textures, we capture all in real world except seven synthetic data created in Blender using free resources in BlenderKit. Original Blender scenes can be found in the raw data.

We provide some reference instructions to reproduce our captured phenomena. These instructions are mainly descriptive references without precise procedures. They indicate the types of temporally varying physical properties included in our dataset: surface bumps, metallicity, wetness, and temperature.

Material Process Duration Instructions
Paper Drying 8 hours Attach paper to metal plate, spray with water, and let it dry.
Ice Melting 3 hours Spray water onto a black acrylic container, freeze in a fridge, and let it melt at room temperature.
Salt Crystallizing 24 hours Boil water, incrementally add more salt and stir till saturated. Filter using filter paper. Transfer the solution to a wide dark container. Cover from dust.
Copper-sulfate Crystallizing 24 hours Same as above, just with copper sulfate.
Honeycomb Melting 30 minutes Place honeycomb in a pot, fix using cookware, and heat.
Watercolor Painting 30 minutes Scribble five colors on paper, mix them for stationarity, and let it dry.
Clay Solidifying 3 hours Mix clay soil with water, spread on an acrylic sheet, and Let it dry.
Copper Patinating 8 hours Soak a copper plate in vinegar and salt for 2 minutes. Put the plate over tissue, and cover it with another tissue to dry out excess drops. Put it into a container. Pour the solution of vinegar and salt around the plate. For oxygen, do not soak the plate.
Steak Cooking 30 minutes Wrap a piece of steak with foil, place it on top of a heater, and keep around 100℃. Use a fan to avoid overheating the capture device.
Cheese Melting 30 minutes Same as above but keep around 80℃ for cheese.
Cress Germinating 5 days Soak cress seeds with water for hours. Pour them evenly into a container lined with a thick layer of tissue. Add sufficient water to keep the tissue moist for the next five days, and replenish when needed. Place the container around room temperature.
