Software
The Matlab INFace toolbox v2.1
The INFace (Illumination Normalization techniques for robust Face recognition) toolbox is a collection of Matlab functions intended for researchers working in the field of face recognition. The toolbox was produced as a byproduct of the research work presented here. It includes implementations of several state-of-the-art photometric normalization techniques and a number of histogram manipulation functions, which can be useful for the task of illumination invariant face recognition.

Face hallucination models
Here we make several state-of-the-art face hallucination models (or face super-resolution models) publicly available for the research community. All models have been trained on the CASIA WebFace dataset (>400k face images). The models have been implemented as part of our research on the paper “Face hallucination using cascaded super-resolution and identity priors” that appeared in the IEEE Transactions on Image Processing, 2020. The code includes our C-SRIP models as well as 10 state-of-the-art face hallucination models from recent top-tier vision conferences. See the C-SRIP homepage for a list of available models. Please cite the associated paper when using the models for you own research work. Commercial use is not allowed.

Facial landmarking code
Facial landmark localization in 3D face data designed specifically to address appearance variability caused by significant pose variations. Our code uses a gating mechanism to incorporate multiple cascaded regression models each trained for a limited range of poses into a single powerful landmarking model capable of processing arbitrary posed input data. Two distinct approaches are developed around the proposed gating mechanism and made publicly available to the research community: i) the first uses a gated multiple ridge descent mechanism in conjunction with established (hand-crafted) HOG features for face alignment, ii) the second simultaneously learns multiple-descent directions as well as binary features that are optimal for the alignment tasks and in addition to competitive results also ensures extremely rapid processing. For more information on the landmarking approach see the project’s homepage. Please cite the associated paper when using the models for you own research work. Commercial use is not allowed.

Datasets
Annotated Web Ears (AWE) toolbox and dataset
Annotated Web Ears (AWE) is a dataset of ear images gathered from the web and in the current form contains 1000 ear images of 100 distinct subjects. The dataset was collected for the goal of studying unconstrained ear recognition and is made publicly available to the community. The dataset comes with a Matlab toolbox dedicated to research in ear recognition. The AWE toolbox implements several state-of-the-art ear recognition techniques and allows for rapid experimentation with the AWE dataset.

The Sclera Blood Vessels, Periocular and Iris (SBVPI) dataset
SBVPI (Sclera Blood Vessels, Periocular and Iris) is a publicly available dataset primarily intended for sclera and periocular recognition research. It was developed at the Faculty of Computer and Information Science, University of Ljubljana in 2018. It consists of 2399 high quality eye images (3000 x 1700 pixels) belonging to 55 different identities. For each identity at least 32 images with 4 different look directions (straight, left, right, up) are available. Each image is annotated with an ID, gender, eye (left/right), view direction and sample number labels. Unlike other similar datasets, it includes corresponding per-pixels annotations of sclera, sclera vascular structures, iris, pupil and periocular region.

MOBIUS (Mobile Ocular Biometrics In Unconstrained Settings)
MOBIUS (Mobile Ocular Biometrics In Unconstrained Settings) is a publicly available dataset primarily intended for mobile ocular recognition research. It was developed at the University of Ljubljana in 2019. It consists of 16,717 RGB images collected from 100 subjects. The images are high-resolution and were captured with the cameras of 3 different commercial mobile phones — Sony Xperia Z5 Compact, Apple iPhone 6s, and Xiaomi Pocophone F1.

Segmentation and Recovery of Superquadric Models using Convolutional Neural Networks
In this paper we address the problem of representing 3D visual data with parameterized volumetric shape primitives. Specifically, we present a (two-stage) approach built around convolutional neural networks (CNNs) capable of segmenting complex depth scenes into the simpler geometric structures that can be represented with superquadric models. In the first stage, our approach uses a Mask-RCNN model to identify superquadric-like structures in depth scenes and then fits superquadric models to the segmented structures using a specially designed CNN regressor. Using our approach we are able to describe complex structures with a small number of interpretable parameters. We evaluated the proposed approach on synthetic as well as real-world depth data and show that our solution does not only result in competitive performance in comparison to the state-of-the-art, but is able to decompose scenes into a number of superquadric models at a fraction of the time required by competing approaches. We make all data and models used in the paper available from https://lmi.fe.uni-lj.si/research/resources/sq-seg/.
