Code and Data

If you use these code and data for your research, please be sure to cite our work (relevant publications can be found in each page).

For recent code and data, see our public github repository. Please note that none of our data and code comes with support and, in most cases, as students graduate we do not have the resources to respond to inquiries.

Local Materials Database

This dataset contains images from PASCAL VOC, MS COCO, and ImageNet supplemented with material region and material segmentation annotations for local material recognition.

Multiview Object Under Natural Illumination Database

A database of images of four objects taken under natural illumination environments with calibrated ground-truth geometry and illumination. Each dataset contains the necessary intrinsic and extrinsic data to align the image data with the coordinate frame of the ground-truth meshes.

defog

A software package for defogging an image: factorizing a single foggy image into scene albedo and depth. It implements our Bayesian defogging method that leverages strong scene-specific priors on both the albedo and depth. This implementation uses non-linear optimization in lieu of graph cuts and achieves signifcant speed up.

rani

A software package for estimating surface reflectance and the (natural) environmental illumination from a single input image of objects with known geometry. It also contains a suite of programs to analyze and synthesize object appearance using the Directional Statistics BRDF (DSBRDF) model.

Texture Database

Images of 20 different textures, each of which is imaged approximately 2,000 times under different light source directions, at multiple distances, and with different in-plane and out-of-plane rotations.

Objects Under Natural Illumination Database

HDR images of 6 objects taken under 5 natural illumination environments with calibrated ground-truth geometry and illumination.

Visual Materil Traits: Trait Annotations

We have augmented the Flickr Materials Database (FMD) of Sharan et al. with binary mask annotations for 13 visual material traits. We consistently annotated FMD images with material trait masks that highlight only local regions indiciative of each trait.

tpg

Two-Point Gait is an easy-to-compute body shape-insensitive image-based representation of human gait. The representation works by modeling the two-point statistics of optical flow fields to primarily encode the relative motion pattern of limbs in a gait cycle. Two-Point Gait provides a faithful representation of the pure gait of a person rather than entangling body shape and gait together.

3DGSS

3D Geometric Scale Space for extracting scale-dependent/invariant features, computing descriptors, and matching them for multiview, multi-scale range image registration.

VisualEyes: Exploring the World in Eyes

You can download VisualEyes, a software that allows you to compute a spherical panorama of the world surrounding a person and an image of exactly what the person is seeing from an eye in an image. It has been more than ten years since I worked on this, so I won’t be able to provide any support.

PSReg

Parallel Simultaneous Registration for robustly aligning multiple range images.
