Description

The images have been taken at the polar bear enclosure at Nuremberg Zoo, which is home to two mature animals (Vera, female adult and Nanuq, male adult). The three on-site cameras acquire videos with a frame rate of 12.5 fps and a resolution of 3840×2160 pixels. For the aim of this project, a period of five days of data (27 April – 1 May 2020) has been selected. During this period, the polar bears shared both enclosures and thus might both be present in a single image. A total of 4450 frames were randomly selected and stored for further labeling. Three biologists annotated all images to provide labels of high quality by assigning labeled bounding boxes to the animals visible in the picture. We provide the resulting mean annotations. As the 4450 images were randomly selected from the video data, only 2099 instances show one or more animals. 167 images show both animals, 1932 only one. 2266 bounding boxes are provided, 1082 for the male and 1184 for the female bear.

Description

This data set contains raw and processed data of gait analysis experiments of level and inclined walking at two speeds for 12 participants. The slopes were uphill and downhill with 8% incline. The raw data contains the output of the force plates and marker data, as well as raw measurements from an K4B2 system. Mat files are processed data: measured metabolic rate, and measured and calculated metabolic cost, as well as kinetic and kinematic data of an averaged gait cycle: joint angles, velocities and moments, ground reaction forces, muscle activation, contractile element length and stimulation, and the duration of the gait cycle.

Description

In this dataset, a full-body three dimensional musculoskeletal model is extended to be specialized for running with directional changes. Model dynamics were implemented implicitly and trajectory optimization problems were solved with direct collocation to enable efficient computation. Standing, straight running, and curved running were simulated starting from a random initial guess to confirm the capabilities of our model and approach: efficacy, tracking and predictive power. Altogether the simulations required 1 h 17 min and corresponded well to the reference data.

Description

This study investigated the feasibility and accuracy of reconstructing, especially change of direction motions with a 3D full-body musculoskeletal model by tracking marker and ground reaction force (GRF) data in optimal control simulations. We recorded in total 30 trials with optical motion capture. Using this data, we compared inverse methods (inverse kinematics and dynamics) to coordinate tracking simulations and marker tracking simulations.

Description

While convolutions are known to be invariant to (discrete) translations, scaling continues to be a challenge and most image recognition networks are not invariant to them. To explore these effects, we have created the Scaled and Translated Image Recognition (STIR) dataset. This dataset contains objects of size s∈[17,64], each randomly placed in a 64×64 pixel image.

The DaLiAc (Daily Life Activities) database consists of data from 19 subjects (8 female and 11 male, age 26 ± 8 years, height 177 ± 11 cm, weight 75.2 ± 14.2 kg, mean ± standard deviation (SD)) that performed 13 daily life activities. These activities were chosen according to their different Metabolic Equivalent of Task (MET) values. Four SHIMMER (Shimmer Research, Dublin, Ireland) sensors were used for data acquisition. Each sensor node was equipped with a triaxial accelerometer and a triaxial gyroscope. Data were sampled with 200 Hz and were stored on SD card. The sensor nodes were placed on the left ankle, the right hip, the chest, and the right ankle.

Description

The EnEx (Energy Expenditure) database consists of data from ten subjects (3 female and 7 male, age 49 ± 12 years, height 178 ± 10 cm, weight 80.7 ± 14.6 kg, mean ± standard deviation (SD)). In one trial, each subject had to run on a traditional treadmill at three different speed levels ([3.2, 4.8, 6.4] km/h). In a second trial, an oscillating treadmill was used imposing different levels of physical activity. Each speed level lasted six minutes. Two SHIMMER sensor nodes were placed on right hip and right ankle. Each sensor node consisted of three accelerometer axes and three gyroscope axes. The sampling rate of the sensor nodes were set to 204.8 Hz. For the expended energy, the oxygen consumption was measured by a spirometry system. The sampling rate was 0.2 Hz.

Description

This dataset provides spatio-temporal gait parameters recorded from 35 Parkinson’s disease patients during real-world gait and unsupervised 4×10 Meter Walking tests.

The data was collected as part of the FallRiskPD study (DRKS-ID: DRKS00015085) between March 2019 and June 2021 by the University Hospital Erlangen, the Hospital Rummelsberg, and the Ernst von Bergmann Hospital Potsdam. Raw data was recorded with the Mobile GaitLab (Portabiles HealthCare Technologies GmbH, Erlangen, Germany), consisting of two foot-worn inertial measurement units placed to the instep of the shoes. The recordings were acquired over the course of approximately two weeks, while the participants were following their activities of daily living and were additionally asked to perform 4×10 Meter Walking tests three times per day with preferred walking speed. After the gait recordings, fall events were captured over three months in a paper-based diary.

The sensor recordings were processed to stride-level spatio temporal gait parameters using a pipeline of gait sequence detection (Ullrich et al., 2020, JBHI), stride segmentation (Barth et al., 2015, Sensors), and event detection with trajectory reconstruction (Rampp et al., 2015, TBME). The following gait parameters are available: stride time [s], stance time [s], swing time [s], stride length [m], gait speed [m/s], IC foot angle [deg], FC foot angle [deg], maximum foot lift [m].

Three files are provided with the data set:

1. strides_realworld_publication.csv: Contains the parameterized strides of the real-world activities including the patient ID, the date and time information, and the IDs of the corresponding walking bouts in which the respective strides can be grouped together.
2. strides_4x10m_pref_at_home_publication.csv: Contains the parameterized strides of the unsupervised 4×10 Meter Walking tets including the patient ID, the date and time information, and the IDs of the corresponding gait tests that are counted with a suffix in the ID within one day.
3. patient_data_publication.csv: Contains the basic patient information including demographics, UPDRS-III score, Hoehn and Yahr stage, and the occurance of falls in the follow up phase.

Description

As stairs are an essential part of our everyday lives and are frequently encountered in urban environments, stair ambulation sequences should be included in mobility analysis. Therefore, this dataset was recorded in January 2021 to enable the development and evaluation of algorithms for human gait analysis using wearable inertial sensors for real-world applications, including level-walking gait as well as stair ascending and stair descending.

Description

The database consists of data from 15 subjects (eleven healthy subjects and four PD patients) that performed the 4×10 m straight walking tests. Data was acquired using two Shimmer3 (Shimmer Research, Dublin, Ireland) sensors laterally attached to the shoes. Data from 3D accelerometer and gyroscope were transmitted to a mobile device. The reference system was a camera-based markerless motion capture (Simi, Unterschleißheim, Germany). Synchronization was assured at the beginning and end of the measurements and the data was aligned accordingly.

Description

The GaitPhase database consists of gait data from 21 subjects (10 male, 11 female, age: 23.8 yrs ± 3.3 yrs, height: 172.8 cm ± 9.4 cm, weight: 66.6 kg ± 10.9 kg; all values are mean ± standard deviation). In total, 25306 steps were acquired. The performed excercise was walking on a split-belt treadmill at 12 different speeds in the interval [0.6, 1.7] m/s with 0.1 m/s increments for one minute at each speed.
Three-dimensional kinematic data using a Qualisys (Qualisys AB, Gothenburg, Sweden) motion capture system with 8 Oqus cameras sampling at 200 Hz and an instrumented Bertec (Bertec Corporation, Columbus, OH, USA) split-belt treadmill with integrated force plates sampling at 1000 Hz were used for data acquisition. Both systems were synchronized camera frame-wise.
